Part of that is making computers easier to fix when something doesn’t work correctly. And even computer troubleshooting isn’t always as difficult as you might think. To demonstrate, this article will give you some simple tips and techniques for how to fix a computer. Here’s a quick rundown of our agenda:

What is troubleshooting?

10 common computer problems and how to troubleshoot them, 7 general tips for troubleshooting computer problems.

Stick with us, and soon you’ll be a basic computer troubleshooting whiz!

“Troubleshooting” usually describes the act of fixing problems that cause machines (especially computers) to stop working, work sub-optimally, or otherwise do something irregular. Specifically, though, it actually refers to a particular problem-solving system that works through several steps.

A basic representation of the troubleshooting process looks something like this:

• Identify the specific problem – Determine exactly what it is your computer is not doing that you want it to do, or doing that you don’t want it to do.
• Consider relations to similar scenarios – Think about problems that you may have had with your computer before that were like your current one. Recall how those problems were solved, and consider what was the same or different in those instances.
• Hypothesize and treat common causes – Brainstorm some simple things that could make your computer not act in the particular way you want it to. Check and fix these things, and then see if that stops the problem and keeps it from coming back soon afterward. If it does, you’re done! If not, proceed to step 4.
• Test relevant components – If none of the common solutions work, methodically check parts (all of them, if you have to) of each system on your computer that could be responsible for the problem.
• Implement a solution on the problem component – If you think you’ve narrowed down what part of your computer is causing your issue, come up with a strategy for how to fix it, and then test it out.
• Verify that the issue is resolved – After working on the allegedly faulty computer component, if the problem is gone and doesn’t quickly start reoccurring (and, therefore, your computer is working normally again), you’re done! If not, go back to step 4.

Now that you know what the troubleshooting process is and how it works, let’s see it in action! Here are some common computer maladies and how to work through them.

1. My computer runs slowly.

General description:

Your computer takes a long time to boot up, programs take a long time to open, and both system and application functions take longer than usual to respond to your inputs.

Common causes:

• You have too many windows open at once, or too many programs running at once.
• Your computer’s registry is fragmented or corrupted.
• Your computer has installed a virus or other malware program.
• Your computer doesn’t have enough RAM to run all the programs you want it to.

Troubleshooting suggestions:

• Close any windows and quit any programs that you aren’t immediately using.
• Go to your Control Panel and uninstall old programs that you don’t use anymore.
• Open your Task Manager and stop programs or processes that don’t need to be running.
• Install and run an antivirus program to repair infected files.
• Take your computer to a repair shop to get its RAM upgraded.

2. I’m stuck on the “Blue Screen of Death.”

This is more officially known as a “STOP error,” and it shows up when your computer’s operating system determines that it can’t run your computer safely at the moment. It has various causes, some of which are more serious than others. Be sure to read the specific error message for hints on what went wrong.

• A piece of hardware on your computer is malfunctioning or is not compatible.
• The software controlling a piece of hardware (i.e. “driver” or “firmware”) is out of date.
• Your main hard disk doesn’t have enough free memory space available on it.
• Your BIOS or other hardware settings are misconfigured.
• Use System Restore to revert your computer to a state where it was working.
• Install updates for your operating system, device drivers, BIOS, and other programs.
• Change the settings for your BIOS and hardware back to their defaults.
• Make sure all hardware components of your computer are properly installed.
• Test your computer’s hardware for failures (likely RAM or hard disk ), and replace if necessary.

3. My computer won’t turn on.

You press the power button and your computer won’t turn on, or it powers up and then promptly shuts down. The good news (if you can call it that) is that this is almost always a hardware problem, so you can usually immediately rule out any software-related culprits.

• One or more power switches to your computer system aren’t turned on.
• Your computer’s power supply or power cord is missing, unplugged, or faulty.
• One or more of your computer’s hardware components are improperly connected or faulty.
• Your computer’s CMOS battery is out of power.
• The power button itself isn’t working.
• Make sure each switch leading to your computer’s power supply is on.
• Make sure all power cables on your computer are connected and set to the correct voltage.
• Remove all intermediary power sources and plug your computer directly into an outlet.
• Disconnect all peripheral devices (mouse, keyboard, etc.) before trying to start your computer.
• Open your computer case and make sure all hardware components are properly connected.
• Replace your CMOS battery .
• Replace your hard drive or motherboard.

4. My computer continually or randomly restarts or shuts down, especially while it’s booting.

Your computer randomly restarts or shuts down on you while you’re using it. Or, shortly after booting up, your computer crashes and shuts down or forces you to restart it. Like the “Blue Screen of Death” (which is sometimes associated with this problem), this can be caused by a few different things, and some of them require more work to fix than others.

• Your operating system is missing a key update.
• One or more of your computer’s device driver programs are out of date.
• Your computer’s motherboard, RAM, and/or hard disk are damaged.

How to troubleshoot it:

• Make sure you have installed all recommended update packages for your operating system.
• Make sure the device drivers for your computer’s hardware components are all up-to-date.
• Install, update, and run an antivirus program to repair infected files.
• Take out a RAM module and start your computer. If it doesn’t work, put it back and try another.
• Replace your hard drive and/or RAM modules, with an experienced repair person if necessary.

5. Parts of my computer are beeping or making strange noises.

You should hear minimal noise coming from your computer if it’s running optimally. But if the hard drive starts beeping, or other hardware parts start making more noise than usual, it could be a sign of a problem with your computer.

• A CD/DVD-ROM or external disk drive may be trying to access files (most of which is normal).
• One or more of your computer’s cooling fans are broken or working sub-optimally.
• A RAM module or other piece of hardware is malfunctioning or is incorrectly installed.
• The hard drive is close to failing.
• The motherboard has detected some other manner of problem .

• Clean your computer fans with something, like a compressed air can, or repair or replace them.
• Check the BIOS settings to make sure they’re running the fans correctly.
• Remove all RAM modules and then properly re-insert them.
• Remove any newly-installed hardware components and re-insert, repair, or replace them.
• Back up the files on your hard drive and then get it replaced.

6. My computer is overheating.

Parts of your computer feel abnormally hot when you touch them or put your extremities near them. This is usually a problem with your computer’s fans or other cooling systems, but that may have indirect causes as well, such as putting a bigger data load on your computer than it can handle.

• The airflow through your computer’s case is restricted or blocked.
• Your BIOS settings are running your computer faster than it can handle (“overclocking”).
• Adjust the BIOS settings to run the fans correctly and not run your CPU faster than it can handle.
• Make sure the vents to and from your computer’s fans aren’t blocked.
• Install and use a program that can control the speed of your computer’s fans.

7. My computer’s peripheral devices, like the mouse and keyboard, aren’t working.

Extra hardware devices that you attach to your computer – like a keyboard, mouse, or external disk drive ­– aren’t working or are acting differently than they normally do. This is mainly a connection or driver issue, but it may be something else.

• One or more of your computer’s connection ports aren’t working properly.
• Settings on your computer regarding the device have been improperly configured.
• The component itself isn’t working due to being damaged or dirty.
• Unplug the faulty device from your computer, then plug it back in (to another port, if you can).
• Go to your Control Panel and change your settings (start with “Ease of Access”).
• Clean the faulty device (taking it apart if you need to), or get it repaired or replaced.

8. My computer suddenly freezes while I’m using it.

You’re using your computer normally, when all of a sudden, the screen stops moving and your input devices don’t respond. It happens to most of us every once in a while, but if it happens repeatedly, you may have a bigger problem on your hands.

• A software program on your computer has experienced an error.
• One or more of your computer’s processes is taking up too much memory and CPU power.
• Open your Task Manager and stop programs that aren’t responding.
• Open your Task Manager and stop processes that are taking up a lot of memory or CPU power.

9. I think my computer has installed a virus or other form of malware.

As we’ve discussed, a virus or malware program can be responsible for all sorts of nasty things that happen to your computer: it slows down, unwantedly runs or changes programs, sporadically restarts or shuts down, repeatedly crashes, and more. Fortunately, its possible causes are relatively limited, and there’s quite a bit that you can do about one.

• You opened or downloaded a file that contained a malware program.
• You connected a device to your computer whose files were infected with malware.
• You visited a website that was infected with malware.
• Disconnect all removable disk drives from your computer.
• Download, install, and update the Microsoft Malicious Software Removal Tool .
• Download, install, and update a leading antivirus program .
• Disconnect your computer from the Internet.
• Reboot your computer in Safe Mode .
• Run the Malicious Software Removal Tool and the antivirus program you installed.
• Re-connect to the Internet.
• Make sure your computer’s built-in Microsoft Security Features are operating and up-to-date.
• Know how to spot and avoid unsafe files and sites on the Internet .
• Install browser extensions to detect and block malware before it reaches your computer.

10. My computer can’t maintain a connection to the Internet.

You can’t use a web browser or other Internet-related service because you can’t connect to the Internet. Or, while you’re using the Internet, you get an error message because your computer has disconnected.

• Your Internet router may not be plugged in or working properly.
• There may be too much distance or interference between your computer and your router.
• The driver for your computer’s network card may be out of date.
• Your computer’s network card may not be receiving the power it needs.
• Make sure your Internet router is plugged in and working. If not, repair or replace it.
• Move your computer closer to your router, and/or move obstacles out of the way.
• Update the driver program for your computer’s network card.
• Go to “Wireless Adapter Settings” in “Power Options” and set to “Maximum Performance.”
• Call your Internet Service Provider and inquire about the problem.

If you’re not quite sure what the problem is, or none of those solutions worked for you, our tips below might help you get your computer up and running again.

1. Turn it off, and then turn it on again.

Shutting down and restarting your computer resets programs and processes that may have been experiencing errors or glitches. This will usually solve minor problems quickly and easily.

2. If you don’t know something, ask!

Write down information that you don’t quite understand as it appears while you troubleshoot, like error messages. Then, discuss it with a computer-savvy friend or family member, or look it up online. Chances are good that someone else knows what it means and what to do about it.

3. Start with simple fixes, and then rule out possibilities from there.

Save yourself time, money, and hassle by starting with the easy solutions first, then trying more complicated fixes if those don’t work.

4. Check your device connections.

Something on your computer may not be working simply because it isn’t plugged in properly, or at all. Make sure all parts are secured snugly to each other and that all sockets are working normally.

5. Boot your computer in Safe Mode.

Starting your computer in Safe Mode disables some advanced functions of your computer. If Safe Mode works fine but a normal boot-up doesn’t, you’ll know that your computer has a problem with something like its device drivers, a rogue start-up program, or a faulty peripheral device.

6. Keep your programs up-to-date.

Updating your software can not only potentially fix current computer problems, but it may prevent future ones by fixing glitches and other security vulnerabilities that can be exploited.

7. If all else fails, re-install the operating system.

This will reset everything, including (theoretically) any programs, malware, or faulty settings that were giving your computer trouble. Make sure to back up your data before you do this, though, because you’ll need to load it back onto the system afterwards.

Communicating the Solution

Once the problem solving cycle is complete, it is important to effectively communicate the solution. This involves explaining the analysis, data, and steps taken to arrive at the solution.

Analyzing the Problem

During the problem solving cycle, a thorough analysis of the problem is conducted. This includes understanding the problem statement, gathering relevant data, and identifying any constraints or limitations. It is important to clearly communicate this analysis to ensure that others understand the problem at hand.

Presenting the Solution

The next step in communicating the solution is presenting the actual solution. This should include a detailed explanation of the steps taken to solve the problem, as well as any algorithms or data structures used. It is important to provide clear and concise descriptions of the solution, so that others can understand and reproduce the results.

Overall, effective communication of the solution in computer science is essential to ensure that others can understand and replicate the problem solving process.

Reflecting and learning are crucial steps in the problem solving cycle in computer science. Once a problem has been solved, it is essential to reflect on the entire process and learn from the experience. This allows for continuous improvement and growth in the field of computer science.

During the reflecting phase, one must analyze and evaluate the problem solving process. This involves reviewing the initial problem statement, understanding the constraints and requirements, and assessing the effectiveness of the chosen algorithm and solution. It is important to consider the efficiency and accuracy of the solution, as well as any potential limitations or areas for optimization.

By reflecting on the problem solving cycle, computer scientists can gain valuable insights into their own strengths and weaknesses. They can identify areas where they excelled and areas where improvement is needed. This self-analysis helps in honing problem solving skills and becoming a better problem solver.

Learning from Mistakes

Mistakes are an integral part of the problem solving cycle, and they provide valuable learning opportunities. When a problem is not successfully solved, it is essential to analyze the reasons behind the failure and learn from them. This involves identifying errors in the algorithm or solution, understanding the underlying concepts or principles that were misunderstood, and finding alternative approaches or strategies.

Failure should not be seen as a setback, but rather as an opportunity for growth. By learning from mistakes, computer scientists can improve their problem solving abilities and expand their knowledge and understanding of computer science. It is through these failures and the subsequent learning process that new ideas and innovations are often born.

Continuous Improvement

Reflecting and learning should not be limited to individual problem solving experiences, but should be an ongoing practice. As computer science is a rapidly evolving field, it is crucial to stay updated with new technologies, algorithms, and problem solving techniques. Continuous learning and improvement contribute to staying competitive and relevant in the field.

Computer scientists can engage in continuous improvement by seeking feedback from peers, participating in research and development activities, attending conferences and workshops, and actively seeking new challenges and problem solving opportunities. This dedication to learning and improvement ensures that one’s problem solving skills remain sharp and effective.

In conclusion, reflecting and learning are integral parts of the problem solving cycle in computer science. They enable computer scientists to refine their problem solving abilities, learn from mistakes, and continuously improve their skills and knowledge. By embracing these steps, computer scientists can stay at the forefront of the ever-changing world of computer science and contribute to its advancements.

Applying Problem Solving in Real Life

In computer science, problem solving is not limited to the realm of programming and algorithms. It is a skill that can be applied to various aspects of our daily lives, helping us to solve problems efficiently and effectively. By using the problem-solving cycle and applying the principles of analysis, data, solution, algorithm, and cycle, we can tackle real-life challenges with confidence and success.

The first step in problem-solving is to analyze the problem at hand. This involves breaking it down into smaller, more manageable parts and identifying the key issues or goals. By understanding the problem thoroughly, we can gain insights into its root causes and potential solutions.

For example, let’s say you’re facing a recurring issue in your daily commute – traffic congestion. By analyzing the problem, you may discover that the main causes are a lack of alternative routes and a lack of communication between drivers. This analysis helps you identify potential solutions such as using navigation apps to find alternate routes or promoting carpooling to reduce the number of vehicles on the road.

Gathering and Analyzing Data

Once we have identified the problem, it is important to gather relevant data to support our analysis. This may involve conducting surveys, collecting statistics, or reviewing existing research. By gathering data, we can make informed decisions and prioritize potential solutions based on their impact and feasibility.

Continuing with the traffic congestion example, you may gather data on the average commute time, the number of vehicles on the road, and the impact of carpooling on congestion levels. This data can help you analyze the problem more accurately and determine the most effective solutions.

Generating and Evaluating Solutions

After analyzing the problem and gathering data, the next step is to generate potential solutions. This can be done through brainstorming, researching best practices, or seeking input from experts. It is important to consider multiple options and think outside the box to find innovative and effective solutions.

For our traffic congestion problem, potential solutions can include implementing a smart traffic management system that optimizes traffic flow or investing in public transportation to incentivize people to leave their cars at home. By evaluating each solution’s potential impact, cost, and feasibility, you can make an informed decision on the best course of action.

Implementing and Iterating

Once a solution has been chosen, it is time to implement it in real life. This may involve developing a plan, allocating resources, and executing the solution. It is important to monitor the progress and collect feedback to learn from the implementation and make necessary adjustments.

For example, if the chosen solution to address traffic congestion is implementing a smart traffic management system, you would work with engineers and transportation authorities to develop and deploy the system. Regular evaluation and iteration of the system’s performance would ensure that it is effective and making a positive impact on reducing congestion.

By applying the problem-solving cycle derived from computer science to real-life situations, we can approach challenges with a systematic and analytical mindset. This can help us make better decisions, improve our problem-solving skills, and ultimately achieve more efficient and effective solutions.

To effectively analyze data, computer scientists can employ various techniques such as data visualization, statistical analysis, and machine learning algorithms. These tools enable them to extract meaningful information from large datasets and make informed decisions during the problem-solving process.

Developing Effective Solutions

Developing effective solutions requires creativity, critical thinking, and logical reasoning. Computer scientists must evaluate multiple approaches, consider various factors, and assess the feasibility of different solutions. They should also consider potential limitations and trade-offs to ensure that the chosen solution addresses the problem effectively.

Furthermore, collaboration and communication skills are vital when building problem-solving skills. Computer scientists often work in teams and need to effectively communicate their ideas, propose solutions, and address any challenges that arise during the problem-solving process. Strong interpersonal skills facilitate collaboration and enhance problem-solving outcomes.

CT involves a number of skills, including:

• Formulating problems in a way that enables us to use a computer and other tools to help solve them
• Logically organizing and analyzing data
• Representing data through abstractions such as models and simulations
• Automating solutions through algorithmic thinking (a series of ordered steps)
• Identifying, analyzing, and implementing possible solutions with the goal of achieving the most efficient and effective combination of steps and resources
• Generalizing and transferring this problem solving process to a wide variety of problems

These skills are supported and enhanced by a number of dispositions or attitudes that include:

• Confidence in dealing with complexity
• Persistence in working with difficult problems
• Tolerance for ambiguity
• The ability to deal with open ended problems
• The ability to communicate and work with others to achieve a common goal or solution

CT concepts are the mental processes (e.g. abstraction, algorithm design, decomposition, pattern recognition, etc) and tangible outcomes (e.g. automation, data representation, pattern generalization, etc) associated with solving problems in computing. These include and are defined as follows:

• Abstraction: Identifying and extracting relevant information to define main idea(s)
• Algorithm Design: Creating an ordered series of instructions for solving similar problems or for doing a task
• Automation: Having computers or machines do repetitive tasks
• Data Analysis: Making sense of data by finding patterns or developing insights
• Data Collection: Gathering information
• Data Representation: Depicting and organizing data in appropriate graphs, charts, words, or images
• Decomposition: Breaking down data, processes, or problems into smaller, manageable parts
• Parallelization: Simultaneous processing of smaller tasks from a larger task to more efficiently reach a common goal
• Pattern Generalization: Creating models, rules, principles, or theories of observed patterns to test predicted outcomes
• Pattern Recognition: Observing patterns, trends, and regularities in data
• Simulation: Developing a model to imitate real-world processes

Why is Python the programming language used in the CT materials?

Python is one of the easier languages to start with that is free and easy to download. It offers users two modes: the interpreter mode and the editor mode. See Introduction to Python for general information on how to introduce and use Python in your curriculum, or visit http://www.python.org/ for general Python information.

Some of the Python programs seem too advanced for my students. How can I adapt the materials to work for my particular students?

In developing our exemplar lessons and examples, we wanted to illustrate the various techniques used in computational thinking, from decomposition to algorithm design and implementation. However, we agree that not all the programming exercises are suitable for all students. Thus we really encourage you to adapt our materials to suit the needs of your classroom, which may be dependent on the computing resources you have available as well as the grade and skill level of your students. Below are some ways in which you may choose to adapt our materials:

• Have students complete all of the exercises that lead up to the programs, and have them explain how they would design such an algorithm in their own words instead of writing actual Python programs
• Expose students to the programs by projecting them, analyzing them step-by-step as a class, and then running them using values and variables provided by your students
• Remove logical code sections from the completed programs and have students work together to fill in the missing parts
• Have students work together to enhance a completed program to solve more sophisticated problems that involve different scenarios

How do I install Python on my computer?

Visit http://www.python.org/ for information on how to download and install Python to your computer. Alternatively, if you are unable or do not want to download Python to your computer, you can search online for ‘online Python editor’ to explore the different web-based Python editors.

Problem-solving is generally considered as one of the most important and challenging cognitive activities in everyday as well as in any professional contexts. Specifically, it is one of the central activities performed by computer scientists as well as by computer science learners. However, it is not a uniform or linear process that can be taught as an algorithm to be followed, and the understanding of this individual process is not always clear. Computer science learners often face difficulties in performing two of the main stages of a problem-solving process: problem analysis and solution construction. Therefore, it is important that computer science educators be aware of these difficulties and acquire appropriate pedagogical tools to guide and scaffold learners in learning these skills. This chapter is dedicated to such pedagogical tools. It presents several problem-solving strategies to address in the MTCS course together with appropriate activities that mediate them to the prospective computer science teachers by enabling them to experience the different strategies.

An algorithmic problem is defined by what is given – the initial conditions of the problem and its goals – the desired state, what should be accomplished. An algorithm problem can be solved with a series of actions formulated formally either by pseudo-code or a programming language. See Sect. 12.4.1 .

In advanced computer science classes, it is relevant to mention that in computer science, in addition to the development of problem-solving strategies, special emphasis is placed also on non-solvable problems (see Sect. 12.4.3 ).

Computer Basics: Basic Troubleshooting Techniques

Lesson 19: basic troubleshooting techniques.

/en/computerbasics/creating-a-safe-workspace/content/

Troubleshooting

Do you know what to do if your screen goes blank? What if you can't seem to close an application, or can't hear any sound from your speakers? Whenever you have a problem with your computer, don't panic! There are many basic troubleshooting techniques you can use to fix issues like this. In this lesson, we'll show you some simple things to try when troubleshooting, as well as how to solve common problems you may encounter.

General tips to keep in mind

There are many different things that could cause a problem with your computer. No matter what's causing the issue, troubleshooting will always be a process of trial and error —in some cases, you may need to use several different approaches before you can find a solution; other problems may be easy to fix. We recommend starting by using the following tips.

• Write down your steps : Once you start troubleshooting, you may want to write down each step you take. This way, you'll be able to remember exactly what you've done and can avoid repeating the same mistakes. If you end up asking other people for help, it will be much easier if they know exactly what you've tried already.
• Take notes about error messages : If your computer gives you an error message , be sure to write down as much information as possible. You may be able to use this information later to find out if other people are having the same error.

• Restart the computer : When all else fails, restarting the computer is a good thing to try. This can solve a lot of basic issues you may experience with your computer.

Using the process of elimination

If you're having an issue with your computer, you may be able to find out what's wrong using the process of elimination . This means you'll make a list of things that could be causing the problem and then test them out one by one to eliminate them. Once you've identified the source of your computer issue, it will be easier to find a solution.

Let's say you're trying to print out invitations for a birthday party, but the printer won't print. You have some ideas about what could be causing this, so you go through them one by one to see if you can eliminate any possible causes.

First, you check the printer to see that it's turned on and plugged in to the surge protector . It is, so that's not the issue. Next, you check to make sure the printer's ink cartridge still has ink and that there is paper loaded in the paper tray . Things look good in both cases, so you know the issue has nothing to do with ink or paper.

Now you want to make sure the printer and computer are communicating correctly . If you recently downloaded an update to your operating system , it might interfere with the printer. But you know there haven't been any recent updates and the printer was working yesterday, so you'll have to look elsewhere.

You check the printer's USB cord and find that it's not plugged in. You must have unplugged it accidentally when you plugged something else into the computer earlier. Once you plug in the USB cord, the printer starts working again. It looks like this printer issue is solved!

This is just one example of an issue you might encounter while using a computer. In the rest of this lesson, we'll talk about other common computer problems and some ways to solve them.

Simple solutions to common problems

Most of the time, problems can be fixed using simple troubleshooting techniques, like closing and reopening the program. It's important to try these simple solutions before resorting to more extreme measures. If the problem still isn't fixed, you can try other troubleshooting techniques.

Problem: Power button will not start computer

• Solution 1 : If your computer does not start , begin by checking the power cord to confirm that it is plugged securely into the back of the computer case and the power outlet.
• Solution 2 : If it is plugged into an outlet, make sure it is a working outlet . To check your outlet, you can plug in another electrical device , such as a lamp .

• Solution 4 : If you are using a laptop , the battery may not be charged. Plug the AC adapter into the wall, then try to turn on the laptop. If it still doesn't start up, you may need to wait a few minutes and try again.

Problem: An application is running slowly

• Solution 1 : Close and reopen the application.

Problem: An application is frozen

Sometimes an application may become stuck, or frozen . When this happens, you won't be able to close the window or click any buttons within the application.

• Solution 2 : Restart the computer. If you are unable to force quit an application, restarting your computer will close all open apps.

Problem: All programs on the computer run slowly

• Solution 2 : Your computer may be running out of hard drive space. Try deleting any files or programs you don't need.
• Solution 3 : If you're using a PC , you can run Disk Defragmenter . To learn more about Disk Defragmenter , check out our lesson on Protecting Your Computer .

Problem: The computer is frozen

Sometimes your computer may become completely unresponsive, or frozen . When this happens, you won't be able to click anywhere on the screen, open or close applications, or access shut-down options.

• Solution 3 : Press and hold the Power button. The Power button is usually located on the front or side of the computer, typically indicated by the power symbol . Press and hold the Power button for 5 to 10 seconds to force the computer to shut down.
• Solution 4 : If the computer still won't shut down, you can unplug the power cable from the electrical outlet. If you're using a laptop, you may be able to remove the battery to force the computer to turn off. Note : This solution should be your last resort after trying the other suggestions above.

Problem: The mouse or keyboard has stopped working

• Solution 2 : If you're using a wireless mouse or keyboard, make sure it's turned on and that its batteries are charged.

Problem: The sound isn't working

• Solution 1 : Check the volume level. Click the audio button in the top-right or bottom-right corner of the screen to make sure the sound is turned on and that the volume is up.
• Solution 2 : Check the audio player controls. Many audio and video players will have their own separate audio controls. Make sure the sound is turned on and that the volume is turned up in the player.
• Solution 3 : Check the cables. Make sure external speakers are plugged in, turned on, and connected to the correct audio port or a USB port. If your computer has color-coded ports, the audio output port will usually be green .

Problem: The screen is blank

• Solution 1 : The computer may be in Sleep mode. Click the mouse or press any key on the keyboard to wake it.
• Solution 2 : Make sure the monitor is plugged in and turned on .
• Solution 3 : Make sure the computer is plugged in and turned on .
• Solution 4 : If you're using a desktop, make sure the monitor cable is properly connected to the computer tower and the monitor.

Solving more difficult problems

If you still haven't found a solution to your problem, you may need to ask someone else for help. As an easy starting point, we'd recommend searching the Web . It's possible that other users have had similar problems, and solutions to these problems are often posted online. Also, if you have a friend or family member who knows a lot about computers, they may be able to help you.

Keep in mind that most computer problems have simple solutions, although it may take some time to find them. For difficult problems, a more drastic solution may be required, like reformatting your hard drive or reinstalling your operating system. If you think you might need a solution like this, we recommend consulting a professional first. If you're not a computer expert, it's possible that attempting these solutions could make the situation worse.

Sysadmin careers: The 5 steps of problem solving

%t min read | by David Both (Sudoer alumni)

Photo by  Robin Schreiner  from  Pexels

In the previous article, 4 problem-solving strategies for sysadmins , we looked at methods of reasoning about problems that relate to computer hardware and software. We saw that problem-solving approaches like MAPs and other symptom-fix methods have significant limitations. It is also clear that proprietary, closed software systems do not lend themselves to reasoned approaches, while open systems like Linux and open source software, in general, are intimately knowable and thus tractable to reason and logic.

One of the best things that my mentors helped me with was the formulation of a defined reasoning process that I could always use for solving problems of nearly any type. That process, the algorithm, is very closely related to the scientific method and is what we will cover in this article.

During the research for my book,  The Linux Philosophy for SysAdmins , I discovered a short article titled,  How the Scientific Method Works , that describes the scientific method using a diagram very much like the one I have created for my "five steps of problem-solving."

Solving problems of any kind is art, science, and—some would say—perhaps a bit of magic, too. Solving technical problems, such as those that occur with computers, requires a good deal of specialized knowledge as well. Any approach to solving problems of any nature —including problems with Linux—must include more than just a list of symptoms and the steps necessary to fix or circumvent the problems that caused the symptoms. This so-called "symptom-fix" approach looks good on paper to many managers, but it really sucks in practice. The best way to approach problem-solving is with a large base of knowledge of the subject and a strong methodology.

The five steps of problem-solving

There are five basic steps that are involved in the problem-solving process, as shown in Figure 1. This algorithm is very similar to that of the scientific method but is specifically intended for solving technical problems.

You probably already follow these steps when you troubleshoot a problem but do not even realize it. These steps are universal and apply to solving most any type of problem, not just problems with computers or Linux. I used these steps for years with various types of problems without realizing it. Having them codified for me made me much more effective at solving problems because, when I became stuck, I could review the steps I had taken, verify where I was in the process, and restart at any appropriate step.

You may have heard a couple of other terms applied to problem-solving in the past. The first three steps of this process are also known as problem determination, that is, finding the root cause of the problem. The last two steps are problem resolution, which is actually fixing the problem.

The next sections cover each of these five steps in more detail.

Knowledge of the subject in which you are attempting to solve a problem is the first step. All of the articles I have seen about the scientific method seem to assume this as a prerequisite. However, the acquisition of knowledge is an ongoing process, driven by curiosity and augmented by the knowledge gained from using the scientific method to explore and learn more through experimentation. You must be knowledgeable about Linux at the very least, and furthermore, you must be knowledgeable about the other factors that can interact with and affect Linux. Hardware, the network, and even environmental factors like temperature, humidity, and the electrical environment in which the Linux system operates can affect it.

Knowledge can be gained by reading books and web sites about Linux and those other topics. You can attend classes, seminars, and conferences. You can also set up a number of physical or virtual Linux computers in a networked environment. And, of course, there is much to learn through interaction with other knowledgeable people. You learn when you resolve a problem or discover a new cause for a particular type of problem, even when an attempt to fix a problem results in a temporary failure.

Classes are also valuable in providing us with new information. My personal preference is to play—uh, experiment—with Linux or a particular piece such as networking, name services, DHCP, Chrony, and more. Then I take a class or two to help me internalize the knowledge I have gained.

Remember, "without knowledge, resistance is futile," to paraphrase the Borg. Knowledge is power.

Observation

The second step in solving the problem is to observe its symptoms. It is important to take note of all of the problem symptoms, but also to observe what is working properly. This is not the time to try to fix the problem; merely observe. Another important part of observation is to ask yourself questions about what you see and what you do not see. Aside from the questions you need to ask that are specific to the problem, there are some general questions to ask:

• Is this problem caused by hardware, Linux, application software, or perhaps by lack of user knowledge or training?
• Is this problem similar to others I have seen?
• Is there an error message?
• Are there any log entries pertaining to the problem?
• What was taking place on the computer just before the error occurred?
• What did I expect to happen if the error had not occurred?
• Has anything about the system hardware or software changed recently?

Other questions will reveal themselves as you work to answer these. The important thing to remember here is not these specific questions, but rather to gather as much information as possible. This increases the knowledge you have about this specific problem instance and aids in finding the solution.

As you gather data, never assume that the information obtained from someone else is correct. Observe everything yourself. This can be a major problem if you are working with someone who is at a remote location. Careful questioning is essential, and tools that allow remote access to the system in question are extremely helpful when attempting to confirm the information that you are given.

Tip: When questioning a person at a remote site, never ask leading questions; they will try to be helpful by answering with what they think you want to hear.

At other times the answers you receive will depend upon how much or how little knowledge the person has of Linux and computers in general. When a person knows—or thinks they know—about computers, the answers you receive may contain assumptions that can be difficult to disprove. Rather than ask. "Did you check…," it is better to have the other person actually perform the task required to check the item. And rather than telling the person what they should see, simply have the user explain or describe to you what they do see. Again, remote access to the machine can allow you to confirm the information you are given.

The best problem solvers are those who never take anything for granted. They never assume that the information they have is 100% accurate or complete. When the information you have seems to contradict itself or the symptoms, start over from the beginning as if you have no information at all.

In almost all of the jobs I have had in the computer business, we have always tried to help each other out, and this was true when I was at IBM. I have always been very good at fixing things, and there were times when I would show up to support another CE who was having a particularly difficult time finding the source of a problem. The first thing I would do is assess the situation. I would ask the primary CE what they had done so far to locate the problem. After that, I would start over from the beginning. I always wanted to see the results myself. Many times that paid off because I would observe something that others had missed. In one very strange incident, I fixed a large computer by sitting on it.

This took place while I was an IBM CE in Lima, Ohio, in about 1976. Two of us were installing an IBM System/3, which was smaller than an IBM mainframe, like a 360 or 370, but still large enough to need a room of its own, high voltage power, and significant air cooling.

We had assembled the main CPU and had started to attach the IBM 1403 line printer controller when we ran into the problem. The printer controller was contained in a slightly lower than desktop-height unit to the left of the CPU. That nice large work surface is just the right height to sit on.

We had just bolted the printer controller to the frame of the CPU and were doing one of the very many checks built into the installation instructions. We connected the leads of an Ohm meter between the frame of the CPU and a specific terminal on the power supply of the printer controller. The result was supposed to be an open circuit, that is, infinite resistance, which would indicate that the hot leads of the power supply were not shorted to the frame. In this case, there was a short—zero resistance—which was bad.

There would not have been a spectacular display of noise and fireworks like you see on TV, but it would have been a problem as it would prevent the computer from powering up. Best to catch this while it was still being assembled rather than later. After an hour of trying to find the problem, we were unable to do so. We called the support center for the System/3 in Boca Raton, Florida, and were guided through several further problem determination steps that were unsuccessful.

A bit frustrated, I sat on the printer control unit. Out of the corner of my eye, I saw the needle on the Ohm meter swing to indicate an open circuit. I mentioned this to the other CE and to Vern in Boca Raton, who would later be one of my own mentors when I went down there for a few years as a Course Development Representative (CSR).

We removed the top, where I had perched, from the controller, and with a bit of luck, found that one of the bolts holding the top to the frame of the printer controller had come loose and fallen into the power supply and caused the short. When I sat on the top of the controller, the frame moved just enough to cause the bolt to no longer make the contact required to produce the short. Removing that loose bolt from the power supply fixed the problem.

Vern, who was responsible for the System/3 support at that time, made some changes to the instructions to cover this problem in case it happened again. He also worked with the manufacturing people to ensure that it did not happen again, putting in place a check to ensure that the bolt was properly tightened during the build process.

The thing to remember is to really observe what is going on in all parts of the system. Pay attention to everything, and don't ignore the slightest clue. Sometimes watching  top ,  htop ,  glances , or one of the other utilities used to monitor the internal functioning of the kernel or the network can provide a momentary glimpse of something—a clue—that gets us started in the right direction.

And sometimes it takes just a bit of luck, like sitting on the printer control unit.

Use reasoning skills to take the information from your observations of the symptoms, your knowledge to determine a probable cause for the problem. We discussed the different types of reasoning in some detail in my previous article  Sysadmin careers:  4 problem-solving strategies . The process of reasoning through your observations of the problem, your knowledge, and your past experience is where art and science combine to produce inspiration, intuition, or some other mystical mental insight into the root cause of the problem.

In some cases, this is a fairly easy process. You can see an error code and look up its meaning from the sources available to you. Or perhaps you observe a symptom that is familiar, and you know what steps might resolve it. You can then apply the vast knowledge you have gained by reading about Linux and the documentation provided with Linux to reason your way to the cause of the problem.

In other cases, it can be a very difficult and lengthy part of the problem determination process. These are the types of cases that can be the most difficult—symptoms you have never seen or a problem that is not resolved by any of the methods you have used. It is these difficult ones that require more work and especially more reasoning applied to them.

It helps to remember that the symptom is not the problem. The problem causes the symptom. You want to discover the true problem, not just the symptom.

Now is the time to perform the appropriate repair action. This is usually the simple part. The hard part is what came before—figuring out what to do. After you know the cause of the problem, it is easy to determine the correct repair action to take. The specific action you take will depend upon the cause(s) of the problem.

Remember, we are fixing the root cause, not just trying to get rid of or cover up the symptom.

Make only one change at a time. If there are several actions that can be taken that might correct the cause of a problem, only make the one change or take the one action that is most likely to resolve the root cause. The selection of the corrective action with the highest probability of fixing the problem is what you are trying to do here. Whether it is your own experience telling you which action to take, or the experiences of others, move down the list from highest to lowest probability, one action at a time. Test the results after each action.

After taking some overt repair action, the repair should be tested. This usually means performing the task that failed in the first place, but it could also be a single, simple command that illustrates the problem.

We make a single change, taking one potential corrective action, and then testing the results of that action. This is the only way we can be certain which corrective action fixed the problem. If we were to take several corrective actions and then test one time, there is no way to know which action was responsible for fixing the problem. This is especially important if we want to walk back those ineffective changes we made after finding the solution.

If the repair action has not been successful, you should begin the procedure over again. If there are additional corrective actions you can take, return to that step and continue doing so until you have run out of possibilities or have learned with to a certainty that you are on the wrong track.

Be sure to check the original observed symptoms when testing. It is possible that they have changed due to the action you have taken, and you need to be aware of this in order to make informed decisions during the next iteration of the process. Even if the problem has not been resolved, the altered symptom could be very valuable in determining how to proceed.

As you work through a problem, it will be necessary to iterate through at least some of the steps. If, for example, performing a given corrective action does not resolve the problem, you may need to try another action that has also been known to resolve the problem in the past. Figure 1 shows that you may need to iterate to any previous step in order to continue. It may be necessary to go back to the observation step and gather more information about the problem. I have also found that sometimes it was a good idea to go back to the knowledge step and gather more basic knowledge. This includes reading or rereading manuals and man pages, using search engines, whatever is necessary to gain the knowledge required to continue past the point where I was blocked.

Be flexible, and don't hesitate to step back and start over if nothing else produces some forward progress.

Concluding thoughts

In this article, we have looked at one way to approach fixing problems that applies to many non-technical things as well as to computer hardware and software. What we have discussed here is one algorithm for problem-solving that can be used with the reasoning methodologies we explored in the first article. The flexibility of this particular combination is extremely powerful.

I am not telling you that you "should" use this method. However, if you go all Zen and analyze your own method for solving problems, you will very likely find that it is already very close to the algorithm I describe here. I suggest that you do take the time to analyze your own methods. I think you will find it a productive use of time that will be quite enlightening.

What is computer programming, exactly? A techie's guide

The 21st-century world runs on computers. And computers run on programs. Understanding computer programming unlocks the power of computing systems -- and programming opens career doors.

Computer programs communicate information to computing devices. Computers then carry out tasks based on the program instructions. Simple programs tell computers to run calculations, while complex programs can run video games, analyze big data, or drive a car.

Our guide defines computer programs, explores uses of programming, and looks at the knowledge and skills required for careers in programming. 

What is computer programming?

What is computer programming? Programming, also known as coding, refers to the process of writing instructions for computing devices and systems. A computer program translates those instructions into a language that computers can understand.  

Computer programmers use many different languages to command computers. Popular programming languages include Python, JavaScript, Java, and the C-languages. 

The tech industry relies on computer programming to create innovative new uses for computers. Groundbreaking fields like machine learning and artificial intelligence depend on computer programming.

Computer users interact with programs frequently. Web browsers, for example, are specialized computer programs. These user-facing programs fall into the category of front-end development . In contrast, back-end development creates programs for tasks the user does not see, including server communication. 

How is computer programming used?

Computer programmers created every application that computers run -- from photo editing software to word processors and web browsers. Programming languages unlock the power of computing systems. And without computer programming, our computing devices would not function. 

In addition to the uses of programming visible to users, programming languages also manage the hidden side of computing. Programs pull information from databases, implement security procedures to protect private data, and operate memory backup systems.

What computer programmers do

Computer programmers write code in languages like JavaScript, Python , and C++. Depending on their focus area -- web development, mobile application development, software engineering, and so on -- they use different languages. 

Computer programmers need more than fluency in one or more programming languages. They also need to know how to debug and modify code. Programmers often work in teams. 

The process of creating a program is complex and involves steps such as:

Conceptualizing the goal of the application

Building a layout of the different parts of the program

Writing code

Debugging the code and resolving any errors

Testing the application 

Releasing the program to beta users

Computer programming jobs

Many tech jobs require programming skills. For example, computer programmers , web developers , software developers , and software engineers all use coding skills regularly. 

According to the Bureau of Labor Statistics , the median annual wage for computer and information technology occupations was $91,250 in May 2020, more than twice the $41,950 median annual wage for all occupations. The best computer science jobs also show growth above the national average.

Other computer programming jobs include:

Database administrator

Computer systems analyst

Information security analyst

Data scientist

Network architect

Becoming a computer programmer

Computer programmers gain coding skills through college programs, coding bootcamps , and self-study. A degree in computer science or programming builds strong coding skills. If you're wondering how to become a software engineer , researching training options is a good place to start.

Students can also enroll in online courses, certificate programs, or bootcamps focused on particular programming languages.

Prospective programmers should consider their strengths and career goals when choosing languages to learn. The easiest programming languages have simple syntax and can provide an entry point for tackling more complex languages. Note that different career paths require different programming languages.

What is computer programming used for?

Programming languages tell computing systems to perform tasks. Programmers code software, hardware, and other applications that allow people to use computers. 

Is computer programming hard?

Learning a programming language requires attention to detail and strong problem-solving skills. Focusing on an easier programming language helps new learners master core programming skills.

What language is used for computer programming?

Computer programmers use many different languages, including JavaScript, Python, C++, and Java. Tech professionals use different languages depending on their goals and focus areas.

Frequently Asked Questions

Problem-solving is a mental process that involves discovering, analyzing, and solving problems. The ultimate goal of problem-solving is to overcome obstacles and find a solution that best resolves the issue.

The best strategy for solving a problem depends largely on the unique situation. In some cases, people are better off learning everything they can about the issue and then using factual knowledge to come up with a solution. In other instances, creativity and insight are the best options.

It is not necessary to follow problem-solving steps sequentially, It is common to skip steps or even go back through steps multiple times until the desired solution is reached.

In order to correctly solve a problem, it is often important to follow a series of steps. Researchers sometimes refer to this as the problem-solving cycle. While this cycle is portrayed sequentially, people rarely follow a rigid series of steps to find a solution.

The following steps include developing strategies and organizing knowledge.

1. Identifying the Problem

While it may seem like an obvious step, identifying the problem is not always as simple as it sounds. In some cases, people might mistakenly identify the wrong source of a problem, which will make attempts to solve it inefficient or even useless.

Some strategies that you might use to figure out the source of a problem include :

• Asking questions about the problem
• Breaking the problem down into smaller pieces
• Looking at the problem from different perspectives
• Conducting research to figure out what relationships exist between different variables

2. Defining the Problem

After the problem has been identified, it is important to fully define the problem so that it can be solved. You can define a problem by operationally defining each aspect of the problem and setting goals for what aspects of the problem you will address

At this point, you should focus on figuring out which aspects of the problems are facts and which are opinions. State the problem clearly and identify the scope of the solution.

3. Forming a Strategy

After the problem has been identified, it is time to start brainstorming potential solutions. This step usually involves generating as many ideas as possible without judging their quality. Once several possibilities have been generated, they can be evaluated and narrowed down.

The next step is to develop a strategy to solve the problem. The approach used will vary depending upon the situation and the individual's unique preferences. Common problem-solving strategies include heuristics and algorithms.

• Heuristics are mental shortcuts that are often based on solutions that have worked in the past. They can work well if the problem is similar to something you have encountered before and are often the best choice if you need a fast solution.
• Algorithms are step-by-step strategies that are guaranteed to produce a correct result. While this approach is great for accuracy, it can also consume time and resources.

Heuristics are often best used when time is of the essence, while algorithms are a better choice when a decision needs to be as accurate as possible.

4. Organizing Information

Before coming up with a solution, you need to first organize the available information. What do you know about the problem? What do you not know? The more information that is available the better prepared you will be to come up with an accurate solution.

When approaching a problem, it is important to make sure that you have all the data you need. Making a decision without adequate information can lead to biased or inaccurate results.

5. Allocating Resources

Of course, we don't always have unlimited money, time, and other resources to solve a problem. Before you begin to solve a problem, you need to determine how high priority it is.

If it is an important problem, it is probably worth allocating more resources to solving it. If, however, it is a fairly unimportant problem, then you do not want to spend too much of your available resources on coming up with a solution.

At this stage, it is important to consider all of the factors that might affect the problem at hand. This includes looking at the available resources, deadlines that need to be met, and any possible risks involved in each solution. After careful evaluation, a decision can be made about which solution to pursue.

6. Monitoring Progress

After selecting a problem-solving strategy, it is time to put the plan into action and see if it works. This step might involve trying out different solutions to see which one is the most effective.

It is also important to monitor the situation after implementing a solution to ensure that the problem has been solved and that no new problems have arisen as a result of the proposed solution.

Effective problem-solvers tend to monitor their progress as they work towards a solution. If they are not making good progress toward reaching their goal, they will reevaluate their approach or look for new strategies .

7. Evaluating the Results

After a solution has been reached, it is important to evaluate the results to determine if it is the best possible solution to the problem. This evaluation might be immediate, such as checking the results of a math problem to ensure the answer is correct, or it can be delayed, such as evaluating the success of a therapy program after several months of treatment.

Once a problem has been solved, it is important to take some time to reflect on the process that was used and evaluate the results. This will help you to improve your problem-solving skills and become more efficient at solving future problems.

A Word From Verywell​

It is important to remember that there are many different problem-solving processes with different steps, and this is just one example. Problem-solving in real-world situations requires a great deal of resourcefulness, flexibility, resilience, and continuous interaction with the environment.

You can become a better problem solving by:

• Practicing brainstorming and coming up with multiple potential solutions to problems
• Being open-minded and considering all possible options before making a decision
• Breaking down problems into smaller, more manageable pieces
• Asking for help when needed
• Researching different problem-solving techniques and trying out new ones
• Learning from mistakes and using them as opportunities to grow

It's important to communicate openly and honestly with your partner about what's going on. Try to see things from their perspective as well as your own. Work together to find a resolution that works for both of you. Be willing to compromise and accept that there may not be a perfect solution.

Take breaks if things are getting too heated, and come back to the problem when you feel calm and collected. Don't try to fix every problem on your own—consider asking a therapist or counselor for help and insight.

If you've tried everything and there doesn't seem to be a way to fix the problem, you may have to learn to accept it. This can be difficult, but try to focus on the positive aspects of your life and remember that every situation is temporary. Don't dwell on what's going wrong—instead, think about what's going right. Find support by talking to friends or family. Seek professional help if you're having trouble coping.

All teams and organizations encounter challenges as they grow. There are problems that might occur for teams when it comes to miscommunication or resolving business-critical issues . You may face challenges around growth , design , user engagement, and even team culture and happiness. In short, problem-solving techniques should be part of every team’s skillset.

Problem-solving methods are primarily designed to help a group or team through a process of first identifying problems and challenges , ideating possible solutions , and then evaluating the most suitable .

Finding effective solutions to complex problems isn’t easy, but by using the right process and techniques, you can help your team be more efficient in the process.

So how do you develop strategies that are engaging, and empower your team to solve problems effectively?

In this blog post, we share a series of problem-solving tools you can use in your next workshop or team meeting. You’ll also find some tips for facilitating the process and how to enable others to solve complex problems.

Let’s get started!

Closing activities for a problem-solving process.

Before you can move towards finding the right solution for a given problem, you first need to identify and define the problem you wish to solve. 

Here, you want to clearly articulate what the problem is and allow your group to do the same. Remember that everyone in a group is likely to have differing perspectives and alignment is necessary in order to help the group move forward. 

Identifying a problem accurately also requires that all members of a group are able to contribute their views in an open and safe manner. It can be scary for people to stand up and contribute, especially if the problems or challenges are emotive or personal in nature. Be sure to try and create a psychologically safe space for these kinds of discussions.

Remember that problem analysis and further discussion are also important. Not taking the time to fully analyze and discuss a challenge can result in the development of solutions that are not fit for purpose or do not address the underlying issue.

Successfully identifying and then analyzing a problem means facilitating a group through activities designed to help them clearly and honestly articulate their thoughts and produce usable insight.

With this data, you might then produce a problem statement that clearly describes the problem you wish to be addressed and also state the goal of any process you undertake to tackle this issue.  

Finding solutions is the end goal of any process. Complex organizational challenges can only be solved with an appropriate solution but discovering them requires using the right problem-solving tool.

After you’ve explored a problem and discussed ideas, you need to help a team discuss and choose the right solution. Consensus tools and methods such as those below help a group explore possible solutions before then voting for the best. They’re a great way to tap into the collective intelligence of the group for great results!

Remember that the process is often iterative. Great problem solvers often roadtest a viable solution in a measured way to see what works too. While you might not get the right solution on your first try, the methods below help teams land on the most likely to succeed solution while also holding space for improvement.

Every effective problem solving process begins with an agenda . A well-structured workshop is one of the best methods for successfully guiding a group from exploring a problem to implementing a solution.

In SessionLab, it’s easy to go from an idea to a complete agenda . Start by dragging and dropping your core problem solving activities into place . Add timings, breaks and necessary materials before sharing your agenda with your colleagues.

The resulting agenda will be your guide to an effective and productive problem solving session that will also help you stay organized on the day!

Tips for more effective problem solving

Problem-solving activities are only one part of the puzzle. While a great method can help unlock your team’s ability to solve problems, without a thoughtful approach and strong facilitation the solutions may not be fit for purpose.

Let’s take a look at some problem-solving tips you can apply to any process to help it be a success!

Clearly define the problem

Jumping straight to solutions can be tempting, though without first clearly articulating a problem, the solution might not be the right one. Many of the problem-solving activities below include sections where the problem is explored and clearly defined before moving on.

This is a vital part of the problem-solving process and taking the time to fully define an issue can save time and effort later. A clear definition helps identify irrelevant information and it also ensures that your team sets off on the right track.

Don’t jump to conclusions

It’s easy for groups to exhibit cognitive bias or have preconceived ideas about both problems and potential solutions. Be sure to back up any problem statements or potential solutions with facts, research, and adequate forethought.

The best techniques ask participants to be methodical and challenge preconceived notions. Make sure you give the group enough time and space to collect relevant information and consider the problem in a new way. By approaching the process with a clear, rational mindset, you’ll often find that better solutions are more forthcoming.  

Try different approaches  

Problems come in all shapes and sizes and so too should the methods you use to solve them. If you find that one approach isn’t yielding results and your team isn’t finding different solutions, try mixing it up. You’ll be surprised at how using a new creative activity can unblock your team and generate great solutions.

Don’t take it personally 

Depending on the nature of your team or organizational problems, it’s easy for conversations to get heated. While it’s good for participants to be engaged in the discussions, ensure that emotions don’t run too high and that blame isn’t thrown around while finding solutions.

You’re all in it together, and even if your team or area is seeing problems, that isn’t necessarily a disparagement of you personally. Using facilitation skills to manage group dynamics is one effective method of helping conversations be more constructive.

Get the right people in the room

Your problem-solving method is often only as effective as the group using it. Getting the right people on the job and managing the number of people present is important too!

If the group is too small, you may not get enough different perspectives to effectively solve a problem. If the group is too large, you can go round and round during the ideation stages.

Creating the right group makeup is also important in ensuring you have the necessary expertise and skillset to both identify and follow up on potential solutions. Carefully consider who to include at each stage to help ensure your problem-solving method is followed and positioned for success.

Document everything

The best solutions can take refinement, iteration, and reflection to come out. Get into a habit of documenting your process in order to keep all the learnings from the session and to allow ideas to mature and develop. Many of the methods below involve the creation of documents or shared resources. Be sure to keep and share these so everyone can benefit from the work done!

Bring a facilitator 

Facilitation is all about making group processes easier. With a subject as potentially emotive and important as problem-solving, having an impartial third party in the form of a facilitator can make all the difference in finding great solutions and keeping the process moving. Consider bringing a facilitator to your problem-solving session to get better results and generate meaningful solutions!

Develop your problem-solving skills

It takes time and practice to be an effective problem solver. While some roles or participants might more naturally gravitate towards problem-solving, it can take development and planning to help everyone create better solutions.

You might develop a training program, run a problem-solving workshop or simply ask your team to practice using the techniques below. Check out our post on problem-solving skills to see how you and your group can develop the right mental process and be more resilient to issues too!

Design a great agenda

Workshops are a great format for solving problems. With the right approach, you can focus a group and help them find the solutions to their own problems. But designing a process can be time-consuming and finding the right activities can be difficult.

Check out our workshop planning guide to level-up your agenda design and start running more effective workshops. Need inspiration? Check out templates designed by expert facilitators to help you kickstart your process!

In this section, we’ll look at in-depth problem-solving methods that provide a complete end-to-end process for developing effective solutions. These will help guide your team from the discovery and definition of a problem through to delivering the right solution.

If you’re looking for an all-encompassing method or problem-solving model, these processes are a great place to start. They’ll ask your team to challenge preconceived ideas and adopt a mindset for solving problems more effectively.

1. Six Thinking Hats

Individual approaches to solving a problem can be very different based on what team or role an individual holds. It can be easy for existing biases or perspectives to find their way into the mix, or for internal politics to direct a conversation.

Six Thinking Hats is a classic method for identifying the problems that need to be solved and enables your team to consider them from different angles, whether that is by focusing on facts and data, creative solutions, or by considering why a particular solution might not work.

Like all problem-solving frameworks, Six Thinking Hats is effective at helping teams remove roadblocks from a conversation or discussion and come to terms with all the aspects necessary to solve complex problems.

2. Lightning Decision Jam

Featured courtesy of Jonathan Courtney of AJ&Smart Berlin, Lightning Decision Jam is one of those strategies that should be in every facilitation toolbox. Exploring problems and finding solutions is often creative in nature, though as with any creative process, there is the potential to lose focus and get lost.

Unstructured discussions might get you there in the end, but it’s much more effective to use a method that creates a clear process and team focus.

In Lightning Decision Jam, participants are invited to begin by writing challenges, concerns, or mistakes on post-its without discussing them before then being invited by the moderator to present them to the group.

From there, the team vote on which problems to solve and are guided through steps that will allow them to reframe those problems, create solutions and then decide what to execute on. 

By deciding the problems that need to be solved as a team before moving on, this group process is great for ensuring the whole team is aligned and can take ownership over the next stages. 

Lightning Decision Jam (LDJ)   #action   #decision making   #problem solving   #issue analysis   #innovation   #design   #remote-friendly   The problem with anything that requires creative thinking is that it’s easy to get lost—lose focus and fall into the trap of having useless, open-ended, unstructured discussions. Here’s the most effective solution I’ve found: Replace all open, unstructured discussion with a clear process. What to use this exercise for: Anything which requires a group of people to make decisions, solve problems or discuss challenges. It’s always good to frame an LDJ session with a broad topic, here are some examples: The conversion flow of our checkout Our internal design process How we organise events Keeping up with our competition Improving sales flow

3. Problem Definition Process

While problems can be complex, the problem-solving methods you use to identify and solve those problems can often be simple in design. 

By taking the time to truly identify and define a problem before asking the group to reframe the challenge as an opportunity, this method is a great way to enable change.

Begin by identifying a focus question and exploring the ways in which it manifests before splitting into five teams who will each consider the problem using a different method: escape, reversal, exaggeration, distortion or wishful. Teams develop a problem objective and create ideas in line with their method before then feeding them back to the group.

This method is great for enabling in-depth discussions while also creating space for finding creative solutions too!

Problem Definition   #problem solving   #idea generation   #creativity   #online   #remote-friendly   A problem solving technique to define a problem, challenge or opportunity and to generate ideas.

4. The 5 Whys 

Sometimes, a group needs to go further with their strategies and analyze the root cause at the heart of organizational issues. An RCA or root cause analysis is the process of identifying what is at the heart of business problems or recurring challenges. 

The 5 Whys is a simple and effective method of helping a group go find the root cause of any problem or challenge and conduct analysis that will deliver results. 

By beginning with the creation of a problem statement and going through five stages to refine it, The 5 Whys provides everything you need to truly discover the cause of an issue.

The 5 Whys   #hyperisland   #innovation   This simple and powerful method is useful for getting to the core of a problem or challenge. As the title suggests, the group defines a problems, then asks the question “why” five times, often using the resulting explanation as a starting point for creative problem solving.

5. World Cafe

World Cafe is a simple but powerful facilitation technique to help bigger groups to focus their energy and attention on solving complex problems.

World Cafe enables this approach by creating a relaxed atmosphere where participants are able to self-organize and explore topics relevant and important to them which are themed around a central problem-solving purpose. Create the right atmosphere by modeling your space after a cafe and after guiding the group through the method, let them take the lead!

Making problem-solving a part of your organization’s culture in the long term can be a difficult undertaking. More approachable formats like World Cafe can be especially effective in bringing people unfamiliar with workshops into the fold. 

World Cafe   #hyperisland   #innovation   #issue analysis   World Café is a simple yet powerful method, originated by Juanita Brown, for enabling meaningful conversations driven completely by participants and the topics that are relevant and important to them. Facilitators create a cafe-style space and provide simple guidelines. Participants then self-organize and explore a set of relevant topics or questions for conversation.

6. Discovery & Action Dialogue (DAD)

One of the best approaches is to create a safe space for a group to share and discover practices and behaviors that can help them find their own solutions.

With DAD, you can help a group choose which problems they wish to solve and which approaches they will take to do so. It’s great at helping remove resistance to change and can help get buy-in at every level too!

This process of enabling frontline ownership is great in ensuring follow-through and is one of the methods you will want in your toolbox as a facilitator.

Discovery & Action Dialogue (DAD)   #idea generation   #liberating structures   #action   #issue analysis   #remote-friendly   DADs make it easy for a group or community to discover practices and behaviors that enable some individuals (without access to special resources and facing the same constraints) to find better solutions than their peers to common problems. These are called positive deviant (PD) behaviors and practices. DADs make it possible for people in the group, unit, or community to discover by themselves these PD practices. DADs also create favorable conditions for stimulating participants’ creativity in spaces where they can feel safe to invent new and more effective practices. Resistance to change evaporates as participants are unleashed to choose freely which practices they will adopt or try and which problems they will tackle. DADs make it possible to achieve frontline ownership of solutions.

7. Design Sprint 2.0

Want to see how a team can solve big problems and move forward with prototyping and testing solutions in a few days? The Design Sprint 2.0 template from Jake Knapp, author of Sprint, is a complete agenda for a with proven results.

Developing the right agenda can involve difficult but necessary planning. Ensuring all the correct steps are followed can also be stressful or time-consuming depending on your level of experience.

Use this complete 4-day workshop template if you are finding there is no obvious solution to your challenge and want to focus your team around a specific problem that might require a shortcut to launching a minimum viable product or waiting for the organization-wide implementation of a solution.

8. Open space technology

Open space technology- developed by Harrison Owen – creates a space where large groups are invited to take ownership of their problem solving and lead individual sessions. Open space technology is a great format when you have a great deal of expertise and insight in the room and want to allow for different takes and approaches on a particular theme or problem you need to be solved.

Start by bringing your participants together to align around a central theme and focus their efforts. Explain the ground rules to help guide the problem-solving process and then invite members to identify any issue connecting to the central theme that they are interested in and are prepared to take responsibility for.

Once participants have decided on their approach to the core theme, they write their issue on a piece of paper, announce it to the group, pick a session time and place, and post the paper on the wall. As the wall fills up with sessions, the group is then invited to join the sessions that interest them the most and which they can contribute to, then you’re ready to begin!

Everyone joins the problem-solving group they’ve signed up to, record the discussion and if appropriate, findings can then be shared with the rest of the group afterward.

Open Space Technology   #action plan   #idea generation   #problem solving   #issue analysis   #large group   #online   #remote-friendly   Open Space is a methodology for large groups to create their agenda discerning important topics for discussion, suitable for conferences, community gatherings and whole system facilitation

Techniques to identify and analyze problems

Using a problem-solving method to help a team identify and analyze a problem can be a quick and effective addition to any workshop or meeting.

While further actions are always necessary, you can generate momentum and alignment easily, and these activities are a great place to get started.

We’ve put together this list of techniques to help you and your team with problem identification, analysis, and discussion that sets the foundation for developing effective solutions.

Let’s take a look!

Individual and group perspectives are incredibly important, but what happens if people are set in their minds and need a change of perspective in order to approach a problem more effectively?

Flip It is a method we love because it is both simple to understand and run, and allows groups to understand how their perspectives and biases are formed. 

Participants in Flip It are first invited to consider concerns, issues, or problems from a perspective of fear and write them on a flip chart. Then, the group is asked to consider those same issues from a perspective of hope and flip their understanding.  

No problem and solution is free from existing bias and by changing perspectives with Flip It, you can then develop a problem solving model quickly and effectively.

Flip It!   #gamestorming   #problem solving   #action   Often, a change in a problem or situation comes simply from a change in our perspectives. Flip It! is a quick game designed to show players that perspectives are made, not born.

10. The Creativity Dice

One of the most useful problem solving skills you can teach your team is of approaching challenges with creativity, flexibility, and openness. Games like The Creativity Dice allow teams to overcome the potential hurdle of too much linear thinking and approach the process with a sense of fun and speed. 

In The Creativity Dice, participants are organized around a topic and roll a dice to determine what they will work on for a period of 3 minutes at a time. They might roll a 3 and work on investigating factual information on the chosen topic. They might roll a 1 and work on identifying the specific goals, standards, or criteria for the session.

Encouraging rapid work and iteration while asking participants to be flexible are great skills to cultivate. Having a stage for idea incubation in this game is also important. Moments of pause can help ensure the ideas that are put forward are the most suitable. 

The Creativity Dice   #creativity   #problem solving   #thiagi   #issue analysis   Too much linear thinking is hazardous to creative problem solving. To be creative, you should approach the problem (or the opportunity) from different points of view. You should leave a thought hanging in mid-air and move to another. This skipping around prevents premature closure and lets your brain incubate one line of thought while you consciously pursue another.

11. Fishbone Analysis

Organizational or team challenges are rarely simple, and it’s important to remember that one problem can be an indication of something that goes deeper and may require further consideration to be solved.

Fishbone Analysis helps groups to dig deeper and understand the origins of a problem. It’s a great example of a root cause analysis method that is simple for everyone on a team to get their head around. 

Participants in this activity are asked to annotate a diagram of a fish, first adding the problem or issue to be worked on at the head of a fish before then brainstorming the root causes of the problem and adding them as bones on the fish. 

Using abstractions such as a diagram of a fish can really help a team break out of their regular thinking and develop a creative approach.

Fishbone Analysis   #problem solving   ##root cause analysis   #decision making   #online facilitation   A process to help identify and understand the origins of problems, issues or observations.

12. Problem Tree 

Encouraging visual thinking can be an essential part of many strategies. By simply reframing and clarifying problems, a group can move towards developing a problem solving model that works for them. 

In Problem Tree, groups are asked to first brainstorm a list of problems – these can be design problems, team problems or larger business problems – and then organize them into a hierarchy. The hierarchy could be from most important to least important or abstract to practical, though the key thing with problem solving games that involve this aspect is that your group has some way of managing and sorting all the issues that are raised.

Once you have a list of problems that need to be solved and have organized them accordingly, you’re then well-positioned for the next problem solving steps.

Problem tree   #define intentions   #create   #design   #issue analysis   A problem tree is a tool to clarify the hierarchy of problems addressed by the team within a design project; it represents high level problems or related sublevel problems.

13. SWOT Analysis

Chances are you’ve heard of the SWOT Analysis before. This problem-solving method focuses on identifying strengths, weaknesses, opportunities, and threats is a tried and tested method for both individuals and teams.

Start by creating a desired end state or outcome and bare this in mind – any process solving model is made more effective by knowing what you are moving towards. Create a quadrant made up of the four categories of a SWOT analysis and ask participants to generate ideas based on each of those quadrants.

Once you have those ideas assembled in their quadrants, cluster them together based on their affinity with other ideas. These clusters are then used to facilitate group conversations and move things forward. 

SWOT analysis   #gamestorming   #problem solving   #action   #meeting facilitation   The SWOT Analysis is a long-standing technique of looking at what we have, with respect to the desired end state, as well as what we could improve on. It gives us an opportunity to gauge approaching opportunities and dangers, and assess the seriousness of the conditions that affect our future. When we understand those conditions, we can influence what comes next.

14. Agreement-Certainty Matrix

Not every problem-solving approach is right for every challenge, and deciding on the right method for the challenge at hand is a key part of being an effective team.

The Agreement Certainty matrix helps teams align on the nature of the challenges facing them. By sorting problems from simple to chaotic, your team can understand what methods are suitable for each problem and what they can do to ensure effective results. 

If you are already using Liberating Structures techniques as part of your problem-solving strategy, the Agreement-Certainty Matrix can be an invaluable addition to your process. We’ve found it particularly if you are having issues with recurring problems in your organization and want to go deeper in understanding the root cause. 

Agreement-Certainty Matrix   #issue analysis   #liberating structures   #problem solving   You can help individuals or groups avoid the frequent mistake of trying to solve a problem with methods that are not adapted to the nature of their challenge. The combination of two questions makes it possible to easily sort challenges into four categories: simple, complicated, complex , and chaotic .  A problem is simple when it can be solved reliably with practices that are easy to duplicate.  It is complicated when experts are required to devise a sophisticated solution that will yield the desired results predictably.  A problem is complex when there are several valid ways to proceed but outcomes are not predictable in detail.  Chaotic is when the context is too turbulent to identify a path forward.  A loose analogy may be used to describe these differences: simple is like following a recipe, complicated like sending a rocket to the moon, complex like raising a child, and chaotic is like the game “Pin the Tail on the Donkey.”  The Liberating Structures Matching Matrix in Chapter 5 can be used as the first step to clarify the nature of a challenge and avoid the mismatches between problems and solutions that are frequently at the root of chronic, recurring problems.

Organizing and charting a team’s progress can be important in ensuring its success. SQUID (Sequential Question and Insight Diagram) is a great model that allows a team to effectively switch between giving questions and answers and develop the skills they need to stay on track throughout the process. 

Begin with two different colored sticky notes – one for questions and one for answers – and with your central topic (the head of the squid) on the board. Ask the group to first come up with a series of questions connected to their best guess of how to approach the topic. Ask the group to come up with answers to those questions, fix them to the board and connect them with a line. After some discussion, go back to question mode by responding to the generated answers or other points on the board.

It’s rewarding to see a diagram grow throughout the exercise, and a completed SQUID can provide a visual resource for future effort and as an example for other teams.

SQUID   #gamestorming   #project planning   #issue analysis   #problem solving   When exploring an information space, it’s important for a group to know where they are at any given time. By using SQUID, a group charts out the territory as they go and can navigate accordingly. SQUID stands for Sequential Question and Insight Diagram.

16. Speed Boat

To continue with our nautical theme, Speed Boat is a short and sweet activity that can help a team quickly identify what employees, clients or service users might have a problem with and analyze what might be standing in the way of achieving a solution.

Methods that allow for a group to make observations, have insights and obtain those eureka moments quickly are invaluable when trying to solve complex problems.

In Speed Boat, the approach is to first consider what anchors and challenges might be holding an organization (or boat) back. Bonus points if you are able to identify any sharks in the water and develop ideas that can also deal with competitors!   

Speed Boat   #gamestorming   #problem solving   #action   Speedboat is a short and sweet way to identify what your employees or clients don’t like about your product/service or what’s standing in the way of a desired goal.

17. The Journalistic Six

Some of the most effective ways of solving problems is by encouraging teams to be more inclusive and diverse in their thinking.

Based on the six key questions journalism students are taught to answer in articles and news stories, The Journalistic Six helps create teams to see the whole picture. By using who, what, when, where, why, and how to facilitate the conversation and encourage creative thinking, your team can make sure that the problem identification and problem analysis stages of the are covered exhaustively and thoughtfully. Reporter’s notebook and dictaphone optional.

The Journalistic Six – Who What When Where Why How   #idea generation   #issue analysis   #problem solving   #online   #creative thinking   #remote-friendly   A questioning method for generating, explaining, investigating ideas.

18. LEGO Challenge

Now for an activity that is a little out of the (toy) box. LEGO Serious Play is a facilitation methodology that can be used to improve creative thinking and problem-solving skills. 

The LEGO Challenge includes giving each member of the team an assignment that is hidden from the rest of the group while they create a structure without speaking.

What the LEGO challenge brings to the table is a fun working example of working with stakeholders who might not be on the same page to solve problems. Also, it’s LEGO! Who doesn’t love LEGO! 

LEGO Challenge   #hyperisland   #team   A team-building activity in which groups must work together to build a structure out of LEGO, but each individual has a secret “assignment” which makes the collaborative process more challenging. It emphasizes group communication, leadership dynamics, conflict, cooperation, patience and problem solving strategy.

19. What, So What, Now What?

If not carefully managed, the problem identification and problem analysis stages of the problem-solving process can actually create more problems and misunderstandings.

The What, So What, Now What? problem-solving activity is designed to help collect insights and move forward while also eliminating the possibility of disagreement when it comes to identifying, clarifying, and analyzing organizational or work problems. 

Facilitation is all about bringing groups together so that might work on a shared goal and the best problem-solving strategies ensure that teams are aligned in purpose, if not initially in opinion or insight.

Throughout the three steps of this game, you give everyone on a team to reflect on a problem by asking what happened, why it is important, and what actions should then be taken. 

This can be a great activity for bringing our individual perceptions about a problem or challenge and contextualizing it in a larger group setting. This is one of the most important problem-solving skills you can bring to your organization.

W³ – What, So What, Now What?   #issue analysis   #innovation   #liberating structures   You can help groups reflect on a shared experience in a way that builds understanding and spurs coordinated action while avoiding unproductive conflict. It is possible for every voice to be heard while simultaneously sifting for insights and shaping new direction. Progressing in stages makes this practical—from collecting facts about What Happened to making sense of these facts with So What and finally to what actions logically follow with Now What . The shared progression eliminates most of the misunderstandings that otherwise fuel disagreements about what to do. Voila!

20. Journalists  

Problem analysis can be one of the most important and decisive stages of all problem-solving tools. Sometimes, a team can become bogged down in the details and are unable to move forward.

Journalists is an activity that can avoid a group from getting stuck in the problem identification or problem analysis stages of the process.

In Journalists, the group is invited to draft the front page of a fictional newspaper and figure out what stories deserve to be on the cover and what headlines those stories will have. By reframing how your problems and challenges are approached, you can help a team move productively through the process and be better prepared for the steps to follow.

Journalists   #vision   #big picture   #issue analysis   #remote-friendly   This is an exercise to use when the group gets stuck in details and struggles to see the big picture. Also good for defining a vision.

The success of any problem-solving process can be measured by the solutions it produces. After you’ve defined the issue, explored existing ideas, and ideated, it’s time to narrow down to the correct solution.

Use these problem-solving techniques when you want to help your team find consensus, compare possible solutions, and move towards taking action on a particular problem.

• Improved Solutions
• Four-Step Sketch
• 15% Solutions
• How-Now-Wow matrix
• Impact Effort Matrix

21. Mindspin  

Brainstorming is part of the bread and butter of the problem-solving process and all problem-solving strategies benefit from getting ideas out and challenging a team to generate solutions quickly. 

With Mindspin, participants are encouraged not only to generate ideas but to do so under time constraints and by slamming down cards and passing them on. By doing multiple rounds, your team can begin with a free generation of possible solutions before moving on to developing those solutions and encouraging further ideation. 

This is one of our favorite problem-solving activities and can be great for keeping the energy up throughout the workshop. Remember the importance of helping people become engaged in the process – energizing problem-solving techniques like Mindspin can help ensure your team stays engaged and happy, even when the problems they’re coming together to solve are complex. 

MindSpin   #teampedia   #idea generation   #problem solving   #action   A fast and loud method to enhance brainstorming within a team. Since this activity has more than round ideas that are repetitive can be ruled out leaving more creative and innovative answers to the challenge.

22. Improved Solutions

After a team has successfully identified a problem and come up with a few solutions, it can be tempting to call the work of the problem-solving process complete. That said, the first solution is not necessarily the best, and by including a further review and reflection activity into your problem-solving model, you can ensure your group reaches the best possible result. 

One of a number of problem-solving games from Thiagi Group, Improved Solutions helps you go the extra mile and develop suggested solutions with close consideration and peer review. By supporting the discussion of several problems at once and by shifting team roles throughout, this problem-solving technique is a dynamic way of finding the best solution. 

Improved Solutions   #creativity   #thiagi   #problem solving   #action   #team   You can improve any solution by objectively reviewing its strengths and weaknesses and making suitable adjustments. In this creativity framegame, you improve the solutions to several problems. To maintain objective detachment, you deal with a different problem during each of six rounds and assume different roles (problem owner, consultant, basher, booster, enhancer, and evaluator) during each round. At the conclusion of the activity, each player ends up with two solutions to her problem.

23. Four Step Sketch

Creative thinking and visual ideation does not need to be confined to the opening stages of your problem-solving strategies. Exercises that include sketching and prototyping on paper can be effective at the solution finding and development stage of the process, and can be great for keeping a team engaged. 

By going from simple notes to a crazy 8s round that involves rapidly sketching 8 variations on their ideas before then producing a final solution sketch, the group is able to iterate quickly and visually. Problem-solving techniques like Four-Step Sketch are great if you have a group of different thinkers and want to change things up from a more textual or discussion-based approach.

Four-Step Sketch   #design sprint   #innovation   #idea generation   #remote-friendly   The four-step sketch is an exercise that helps people to create well-formed concepts through a structured process that includes: Review key information Start design work on paper,  Consider multiple variations , Create a detailed solution . This exercise is preceded by a set of other activities allowing the group to clarify the challenge they want to solve. See how the Four Step Sketch exercise fits into a Design Sprint

24. 15% Solutions

Some problems are simpler than others and with the right problem-solving activities, you can empower people to take immediate actions that can help create organizational change. 

Part of the liberating structures toolkit, 15% solutions is a problem-solving technique that focuses on finding and implementing solutions quickly. A process of iterating and making small changes quickly can help generate momentum and an appetite for solving complex problems.

Problem-solving strategies can live and die on whether people are onboard. Getting some quick wins is a great way of getting people behind the process.   

It can be extremely empowering for a team to realize that problem-solving techniques can be deployed quickly and easily and delineate between things they can positively impact and those things they cannot change. 

15% Solutions   #action   #liberating structures   #remote-friendly   You can reveal the actions, however small, that everyone can do immediately. At a minimum, these will create momentum, and that may make a BIG difference.  15% Solutions show that there is no reason to wait around, feel powerless, or fearful. They help people pick it up a level. They get individuals and the group to focus on what is within their discretion instead of what they cannot change.  With a very simple question, you can flip the conversation to what can be done and find solutions to big problems that are often distributed widely in places not known in advance. Shifting a few grains of sand may trigger a landslide and change the whole landscape.

25. How-Now-Wow Matrix

The problem-solving process is often creative, as complex problems usually require a change of thinking and creative response in order to find the best solutions. While it’s common for the first stages to encourage creative thinking, groups can often gravitate to familiar solutions when it comes to the end of the process. 

When selecting solutions, you don’t want to lose your creative energy! The How-Now-Wow Matrix from Gamestorming is a great problem-solving activity that enables a group to stay creative and think out of the box when it comes to selecting the right solution for a given problem.

Problem-solving techniques that encourage creative thinking and the ideation and selection of new solutions can be the most effective in organisational change. Give the How-Now-Wow Matrix a go, and not just for how pleasant it is to say out loud. 

How-Now-Wow Matrix   #gamestorming   #idea generation   #remote-friendly   When people want to develop new ideas, they most often think out of the box in the brainstorming or divergent phase. However, when it comes to convergence, people often end up picking ideas that are most familiar to them. This is called a ‘creative paradox’ or a ‘creadox’. The How-Now-Wow matrix is an idea selection tool that breaks the creadox by forcing people to weigh each idea on 2 parameters.

26. Impact and Effort Matrix

All problem-solving techniques hope to not only find solutions to a given problem or challenge but to find the best solution. When it comes to finding a solution, groups are invited to put on their decision-making hats and really think about how a proposed idea would work in practice. 

The Impact and Effort Matrix is one of the problem-solving techniques that fall into this camp, empowering participants to first generate ideas and then categorize them into a 2×2 matrix based on impact and effort.

Activities that invite critical thinking while remaining simple are invaluable. Use the Impact and Effort Matrix to move from ideation and towards evaluating potential solutions before then committing to them. 

Impact and Effort Matrix   #gamestorming   #decision making   #action   #remote-friendly   In this decision-making exercise, possible actions are mapped based on two factors: effort required to implement and potential impact. Categorizing ideas along these lines is a useful technique in decision making, as it obliges contributors to balance and evaluate suggested actions before committing to them.

27. Dotmocracy

If you’ve followed each of the problem-solving steps with your group successfully, you should move towards the end of your process with heaps of possible solutions developed with a specific problem in mind. But how do you help a group go from ideation to putting a solution into action? 

Dotmocracy – or Dot Voting -is a tried and tested method of helping a team in the problem-solving process make decisions and put actions in place with a degree of oversight and consensus. 

One of the problem-solving techniques that should be in every facilitator’s toolbox, Dot Voting is fast and effective and can help identify the most popular and best solutions and help bring a group to a decision effectively. 

Dotmocracy   #action   #decision making   #group prioritization   #hyperisland   #remote-friendly   Dotmocracy is a simple method for group prioritization or decision-making. It is not an activity on its own, but a method to use in processes where prioritization or decision-making is the aim. The method supports a group to quickly see which options are most popular or relevant. The options or ideas are written on post-its and stuck up on a wall for the whole group to see. Each person votes for the options they think are the strongest, and that information is used to inform a decision.

All facilitators know that warm-ups and icebreakers are useful for any workshop or group process. Problem-solving workshops are no different.

Use these problem-solving techniques to warm up a group and prepare them for the rest of the process. Activating your group by tapping into some of the top problem-solving skills can be one of the best ways to see great outcomes from your session.

• Check-in/Check-out
• Doodling Together
• Show and Tell
• Constellations
• Draw a Tree

28. Check-in / Check-out

Solid processes are planned from beginning to end, and the best facilitators know that setting the tone and establishing a safe, open environment can be integral to a successful problem-solving process.

Check-in / Check-out is a great way to begin and/or bookend a problem-solving workshop. Checking in to a session emphasizes that everyone will be seen, heard, and expected to contribute. 

If you are running a series of meetings, setting a consistent pattern of checking in and checking out can really help your team get into a groove. We recommend this opening-closing activity for small to medium-sized groups though it can work with large groups if they’re disciplined!

Check-in / Check-out   #team   #opening   #closing   #hyperisland   #remote-friendly   Either checking-in or checking-out is a simple way for a team to open or close a process, symbolically and in a collaborative way. Checking-in/out invites each member in a group to be present, seen and heard, and to express a reflection or a feeling. Checking-in emphasizes presence, focus and group commitment; checking-out emphasizes reflection and symbolic closure.

29. Doodling Together  

Thinking creatively and not being afraid to make suggestions are important problem-solving skills for any group or team, and warming up by encouraging these behaviors is a great way to start. 

Doodling Together is one of our favorite creative ice breaker games – it’s quick, effective, and fun and can make all following problem-solving steps easier by encouraging a group to collaborate visually. By passing cards and adding additional items as they go, the workshop group gets into a groove of co-creation and idea development that is crucial to finding solutions to problems. 

Doodling Together   #collaboration   #creativity   #teamwork   #fun   #team   #visual methods   #energiser   #icebreaker   #remote-friendly   Create wild, weird and often funny postcards together & establish a group’s creative confidence.

30. Show and Tell

You might remember some version of Show and Tell from being a kid in school and it’s a great problem-solving activity to kick off a session.

Asking participants to prepare a little something before a workshop by bringing an object for show and tell can help them warm up before the session has even begun! Games that include a physical object can also help encourage early engagement before moving onto more big-picture thinking.

By asking your participants to tell stories about why they chose to bring a particular item to the group, you can help teams see things from new perspectives and see both differences and similarities in the way they approach a topic. Great groundwork for approaching a problem-solving process as a team! 

Show and Tell   #gamestorming   #action   #opening   #meeting facilitation   Show and Tell taps into the power of metaphors to reveal players’ underlying assumptions and associations around a topic The aim of the game is to get a deeper understanding of stakeholders’ perspectives on anything—a new project, an organizational restructuring, a shift in the company’s vision or team dynamic.

31. Constellations

Who doesn’t love stars? Constellations is a great warm-up activity for any workshop as it gets people up off their feet, energized, and ready to engage in new ways with established topics. It’s also great for showing existing beliefs, biases, and patterns that can come into play as part of your session.

Using warm-up games that help build trust and connection while also allowing for non-verbal responses can be great for easing people into the problem-solving process and encouraging engagement from everyone in the group. Constellations is great in large spaces that allow for movement and is definitely a practical exercise to allow the group to see patterns that are otherwise invisible. 

Constellations   #trust   #connection   #opening   #coaching   #patterns   #system   Individuals express their response to a statement or idea by standing closer or further from a central object. Used with teams to reveal system, hidden patterns, perspectives.

32. Draw a Tree

Problem-solving games that help raise group awareness through a central, unifying metaphor can be effective ways to warm-up a group in any problem-solving model.

Draw a Tree is a simple warm-up activity you can use in any group and which can provide a quick jolt of energy. Start by asking your participants to draw a tree in just 45 seconds – they can choose whether it will be abstract or realistic. 

Once the timer is up, ask the group how many people included the roots of the tree and use this as a means to discuss how we can ignore important parts of any system simply because they are not visible.

All problem-solving strategies are made more effective by thinking of problems critically and by exposing things that may not normally come to light. Warm-up games like Draw a Tree are great in that they quickly demonstrate some key problem-solving skills in an accessible and effective way.

Draw a Tree   #thiagi   #opening   #perspectives   #remote-friendly   With this game you can raise awarness about being more mindful, and aware of the environment we live in.

Each step of the problem-solving workshop benefits from an intelligent deployment of activities, games, and techniques. Bringing your session to an effective close helps ensure that solutions are followed through on and that you also celebrate what has been achieved.

Here are some problem-solving activities you can use to effectively close a workshop or meeting and ensure the great work you’ve done can continue afterward.

• One Breath Feedback
• Who What When Matrix
• Response Cards

How do I conclude a problem-solving process?

All good things must come to an end. With the bulk of the work done, it can be tempting to conclude your workshop swiftly and without a moment to debrief and align. This can be problematic in that it doesn’t allow your team to fully process the results or reflect on the process.

At the end of an effective session, your team will have gone through a process that, while productive, can be exhausting. It’s important to give your group a moment to take a breath, ensure that they are clear on future actions, and provide short feedback before leaving the space. 

The primary purpose of any problem-solving method is to generate solutions and then implement them. Be sure to take the opportunity to ensure everyone is aligned and ready to effectively implement the solutions you produced in the workshop.

Remember that every process can be improved and by giving a short moment to collect feedback in the session, you can further refine your problem-solving methods and see further success in the future too.

33. One Breath Feedback

Maintaining attention and focus during the closing stages of a problem-solving workshop can be tricky and so being concise when giving feedback can be important. It’s easy to incur “death by feedback” should some team members go on for too long sharing their perspectives in a quick feedback round. 

One Breath Feedback is a great closing activity for workshops. You give everyone an opportunity to provide feedback on what they’ve done but only in the space of a single breath. This keeps feedback short and to the point and means that everyone is encouraged to provide the most important piece of feedback to them. 

One breath feedback   #closing   #feedback   #action   This is a feedback round in just one breath that excels in maintaining attention: each participants is able to speak during just one breath … for most people that’s around 20 to 25 seconds … unless of course you’ve been a deep sea diver in which case you’ll be able to do it for longer.

34. Who What When Matrix 

Matrices feature as part of many effective problem-solving strategies and with good reason. They are easily recognizable, simple to use, and generate results.

The Who What When Matrix is a great tool to use when closing your problem-solving session by attributing a who, what and when to the actions and solutions you have decided upon. The resulting matrix is a simple, easy-to-follow way of ensuring your team can move forward. 

Great solutions can’t be enacted without action and ownership. Your problem-solving process should include a stage for allocating tasks to individuals or teams and creating a realistic timeframe for those solutions to be implemented or checked out. Use this method to keep the solution implementation process clear and simple for all involved. 

Who/What/When Matrix   #gamestorming   #action   #project planning   With Who/What/When matrix, you can connect people with clear actions they have defined and have committed to.

35. Response cards

Group discussion can comprise the bulk of most problem-solving activities and by the end of the process, you might find that your team is talked out! 

Providing a means for your team to give feedback with short written notes can ensure everyone is head and can contribute without the need to stand up and talk. Depending on the needs of the group, giving an alternative can help ensure everyone can contribute to your problem-solving model in the way that makes the most sense for them.

Response Cards is a great way to close a workshop if you are looking for a gentle warm-down and want to get some swift discussion around some of the feedback that is raised. 

Response Cards   #debriefing   #closing   #structured sharing   #questions and answers   #thiagi   #action   It can be hard to involve everyone during a closing of a session. Some might stay in the background or get unheard because of louder participants. However, with the use of Response Cards, everyone will be involved in providing feedback or clarify questions at the end of a session.

Six Steps to Develop an Effective Problem-Solving Process

by Rawzaba Alhalabi Published on November 1, 2017

Problem-solving involves thought and understanding. Although it may appear simple, identifying a problem may be a challenging process.

“Problems are only opportunities in work clothes”, says American industrialist Henry Kaiser. According to Concise Oxford Dictionary (1995), a problem is “ doubtful or difficult matter requiring a solution” and “something hard to understand or accomplish or deal with.” Such situations are at the center of what many people do at work every day.

Whether to help a client solve a problem, support a problem-solver, or to discover new problems, problem-solving is a crucial element to the workplace ingredients. Everyone can benefit from effective problem-solving skills that would make people happier. Everyone wins. Hence, this approach is a critical element but how can you do it effectively? You need to find a solution, but not right away. People tend to put the solution at the beginning of the process but they actually needed it at the end of the process.

Here are six steps to an effective problem-solving process:

Identify the issues, understand everyone’s interests, list the possible solutions, make a decision, implement the solution.

By following the whole process, you will be able to enhance your problem-solving skills and increase your patience. Keep in mind that effective problem solving does take some time and attention. You have to always be ready to hit the brakes and slow down. A problem is like a bump road. Take it right and you’ll find yourself in good shape for the straightaway that follows. Take it too fast and you may not be in as good shape.

Case study 1:

According to Real Time Economics, there are industries that have genuinely evolved, with more roles for people with analytical and problem-solving skills. In healthcare, for example, a regulatory change requiring the digitization of health records has led to greater demand for medical records technicians. Technological change in the manufacturing industry has reduced routine factory jobs while demanding more skilled workers who can operate complex machinery.

Case study 2:

Yolanda was having a hard time dealing with difficult clients and dealing with her team at the office, so she decided to take a problem-solving course. “I was very pleased with the 2-day Problem Solving program at RSM.  It is an excellent investment for anyone involved in the strategic decision-making process—be it in their own company or as a consultant charged with supporting organizations facing strategic challenges.“
