Determine The Root Cause: 5 Whys - iSixSigma

 

5 why problem solving

The 5 Whys technique is a simple and effective tool for solving problems. Its primary goal is to find the exact reason that causes a given problem by asking a sequence of “Why” questions. The 5 Whys method helps your team focus on finding the root cause of any problem. Sep 19,  · This 5 whys analysis makes it relatively simple to find out what the real root cause of the problem is. The problem-solving journey starts with a clear formulation of what exactly is going on. Once the root cause has been identified, there is no more need for the ‘why’ questions. The root cause is often closely associated with previously 5/5(4). Getting to Root Causes, Fast!

Five Whys - Wikipedia


Have you ever had a problem that refused to go away? No matter what you did, sooner or 5 why problem solving it would return, perhaps 5 why problem solving another form.

Stubborn or recurrent problems are often symptoms of deeper issues, 5 why problem solving. 5 why problem solving this article and in the video, below, we look at the 5 Whys technique sometimes known as 5Y. This is a simple but powerful tool for cutting quickly through the outward symptoms of a problem to reveal its underlying causes, so that you can deal with it once and for all.

Sakichi Toyoda, the Japanese industrialist, inventor, 5 why problem solving, and founder of Toyota Industries, developed the 5 Whys technique in the s. It became popular in the s, and Toyota still uses it to solve problems today. Toyota has a "go and see" philosophy. The 5 Whys technique is true to this tradition, and it is most effective when the answers come from people who have hands-on experience of the process or problem in question, 5 why problem solving.

The method is remarkably simple: when a problem occurs, you drill down to its root cause by asking "Why? Then, when a counter-measure becomes apparent, you follow it through to prevent the issue from recurring.

The 5 Whys uses "counter-measures," rather than "solutions. As such, counter-measures are more robust, and will more likely prevent the problem from recurring. You can use 5 Whys for troubleshooting, quality improvement, 5 why problem solving, and problem solving, but it is most effective when used to resolve simple or moderately difficult problems. It may not be suitable if you need to tackle a complex or critical problem. This is because 5 Whys can lead you to pursue a single track, or a limited number of tracks, of inquiry when, in fact, there could be multiple causes.

This simple technique, however, can often direct you quickly to the root cause of a problem. So, whenever a system or process isn't working properly, give it a try before you embark on a more in-depth approach — and certainly before you attempt to develop a solution. The tool's simplicity gives it great flexibility, too, and 5 Whys combines well with other methods and techniques, such as Root Cause Analysis.

Gather together people who are familiar with the specifics of the problem, and with the process that you're trying to fix. If you can, observe the problem in action. Discuss it with your team and write a brief, clear problem statement that you all agree on.

For example, "Team A isn't meeting its response time targets" or "Software release B resulted in too many rollback failures. Then, write your statement on a whiteboard or sticky note, leaving enough space around it to add your answers to the repeated question, "Why? Ask your 5 why problem solving why the problem is occurring. For example, "Why isn't Team A meeting its response time targets?

Asking "Why? Search for answers that are grounded in fact: they must be accounts of things that have actually happened, not guesses at what might have happened. This prevents 5 Whys from becoming just a process of deductive reasoning, which can generate a large number of possible causes and, sometimes, create more confusion as you chase down hypothetical problems.

Your team members may come up with one obvious reason why, or several plausible ones. Record their answers as succinct phrases, rather than as single words or lengthy statements, and write them below or beside your problem statement. For example, saying "volume of calls is too high" is better than a vague "overloaded.

For each of the answers that you generated in Step 3, ask four further "whys" in succession, 5 why problem solving. Each time, frame the question in response to the answer you've just recorded. Try to move quickly from one question to the next, so that you have the full picture before you jump to any conclusions.

The 5 Whys method also allows you to follow multiple lanes of inquiry. An example of this is shown in Figure 2, below. In our example, asking "Why was the delivery late? Similarly, asking "Why did the job take longer than expected?

Another "Why? There is also a second reason for "Why we ran out of printer ink" Reason 2and a single answer for the next "Why? You'll know that you've revealed the root cause of the problem when asking "why" produces no more useful responses, and you can go no further, 5 why problem solving. An appropriate counter-measure or process change should then become evident.

If you identified more than one reason in Step 5 why problem solving, repeat this process for each of the different branches of 5 why problem solving analysis until you reach a root cause for each one. The "5" in 5 Whys is really just a " rule of thumb. In other cases, you may reach this point before you ask your fifth "Why?

As you work through your chain of questions, you may find that someone has failed to take a necessary action. The great thing about 5 Whys is that it prompts you to go further than just assigning blameand to ask why that happened. This often points to organizational issues or areas where processes need to be improved. Now that you've identified at least one root cause, you need to discuss and agree on the counter-measures that will prevent the problem from recurring.

Keep a close watch on how effectively your counter-measures eliminate or minimize the initial problem. You may need to amend them, or replace them entirely. If this happens, it's a good idea to repeat the 5 Whys process to ensure that you've identified the correct root cause. The 5 Whys strategy is a simple, effective tool for uncovering the root of a problem.

You can use it in troubleshooting, problem-solving, and quality-improvement initiatives. Start with a problem and ask why it is occurring. Make sure that your answer is grounded in fact, 5 why problem solving, and then ask the question again. Continue the process until you reach the root cause of the problem, and you can identify a counter-measure that will prevent it from recurring.

Bear in mind that this questioning process is best suited to simple or moderately difficult problems. Complex problems may benefit from a more detailed approach, although using 5 Whys will still give you useful insights.
