How did the fishbone technique get its name?
The fishbone technique gets its name from the look that is developed when writing it down on a piece of paper. You can see an outline of a fishbone technique in this image: In this option, the tail of the fish is the main problem, each of the whys goes along the sides, and the final effects (or root cause) are up front.
Why are there 5 whys?
The primary goal of the five whys is to take a problem and find the root cause so it can be addressed. When done properly, a company can find the root cause of the problem so that they can take actions to prevent it from happening again in the future. One of the best things about the five whys is that it is extremely inexpensive to implement.
Why are the 5 whys important?
Implementing the usage of the five whys can help companies in any industry to better understand their issues, and give them a more clear roadmap on how they can be addressed permanently.
When do you stop using the 5 whys?
When using the 5 whys, people usually stop the process once they have found a root cause to the problem. In situations where there are multiple root causes contributing to the problem, this can be an issue. The process is limited to the knowledge that the person performing it has.
Can you identify a symptom as a root cause?
People often identify a symptom as a root cause. It can take a significant amount of practice to consistently dig down to the true root cause. This process isn't always consistent. Different people performing the analysis on the same problem will often come up with different answers.
What is the purpose of the 5 whys?
Five whys (or 5 whys) is an iterative interrogative technique used to explore the cause-and-effect relationships underlying a particular problem . The primary goal of the technique is to determine the root cause of a defect or problem by repeating the question "Why?". Each answer forms the basis of the next question. The "five" in the name derives from an anecdotal observation on the number of iterations needed to resolve the problem.
How to distinguish causes from symptoms?
Distinguish causes from symptoms. Pay attention to the logic of cause-and-effect relationship. Make sure that root causes certainly led to the mistake by reversing the sentences created as a result of the analysis with the use of the expression "and therefore". Try to make answers more precise.
Why is the number 5 in the name of the method?
The "five" in the name derives from an anecdotal observation on the number of iterations needed to resolve the problem. Not all problems have a single root cause. If one wishes to uncover multiple root causes, the method must be repeated asking a different sequence of questions each time.
Who developed the Toyota tyre?
History. The technique was originally developed by Sakichi Toyoda and was used within the Toyota Motor Corporation during the evolution of its manufacturing methodologies. It is a critical component of problem-solving training, delivered as part of the induction into the Toyota Production System.
The origin of the 5 Whys
The 5 Whys technique was developed and fine-tuned within the Toyota Motor Corporation as a critical component of its problem-solving training.
How the 5 Whys process works
At our startup, we perform a “5 Whys” after something unexpected has occurred—and that means we perform them a lot! We keep a “5 Whys” folder in our team’s Dropbox Paper account, and the folder has 20+ notes files and counting (not to mention the 5 Whys docs that might not be categorized into the folder).
The 5 main steps to the the 5 Whys
As soon as the problem or situation is identified (and all immediate concerns are dealt with), invite anyone at all on the team who was affected or noticed the issue to be involved in a 5 Whys meeting. As a remote team, we hold ours via Zoom.
Some real-life 5 Whys examples
To take the 5 Whys from theoretical to actual, here’s a look at a few moments in Buffer’s history that have called for a 5 Whys meeting.
The 5 Whys in daily life
Although the 5 Whys is most widely used for manufacturing/development use, I’ve found that it is also quite applicable to daily life in any situation where one might seek deeper understanding—of a problem, a challenge or even a motivation behind an action.
Over to you
What sort of process do you use to get to the root of unexpected situations or challenges in your work or life? Have you ever tried the 5 Whys?
When to Use
While both methods are techniques to expand the horizon of a team searching for answers, there are distinct uses for five whys and five hows. However, both of these two techniques force a team to develop a better and more detailed understanding of a problem or solution and will be helpful in the root cause analysis process.
Five Whys and Five Hows Resources
You can also search articles, case studies, and publications for five whys and five hows resources.
Origin
Sakichi Toyoda, one of the fathers of the Japanese industrial revolution and the founder of Toyota Industries Corporation developed this technique in the 1930s. By 1970s, this method became popular and Toyota and many other firms are still using this it to solve problems.
How to Complete the 5 Whys
Here the team members who gathered should be the ones familiar with details, affected or noticed the problem.
Limitations of the 5 Whys
5 whys will not help us in root cause analysis if the cause is unknown. That is, we cannot reach to counter measure if the person or team doing this type of analysis doesn’t know the problem or couldn’t provide meaningful answers to the questions.

Overview
Five whys (or 5 whys) is an iterative interrogative technique used to explore the cause-and-effect relationships underlying a particular problem. The primary goal of the technique is to determine the root cause of a defect or problem by repeating the question "Why?". Each answer forms the basis of the next question. The "five" in the name derives from an anecdotal observation on the number of iterations needed to resolve the problem.
Example
An example of a problem is: The vehicle will not start.
1. Why? – The battery is dead. (First why)
2. Why? – The alternator is not functioning. (Second why)
3. Why? – The alternator belt has broken. (Third why)
History
The technique was originally developed by Sakichi Toyoda and was used within the Toyota Motor Corporation during the evolution of its manufacturing methodologies. It is a critical component of problem-solving training, delivered as part of the induction into the Toyota Production System. The architect of the Toyota Production System, Taiichi Ohno, described the five whys method as "the basis of Toyota's scientific approach by repeating why five times the nature of the problem as w…
Techniques
Two primary techniques are used to perform a five whys analysis:
• the fishbone (or Ishikawa) diagram
• a tabular format
These tools allow for analysis to be branched in order to provide multiple root causes.
Rules of performing a five whys analysis
In order to carry out a five whys analysis properly, the following advice should be followed:
1. It is necessary to engage the management in the five whys process in the company. For the analysis itself, consider what is the right working group. Also consider bringing in a facilitator for more difficult topics.
2. Use paper or whiteboard instead of computers.
Criticism
The five whys have been criticized as a poor tool for root cause analysis. Teruyuki Minoura, former managing director of global purchasing for Toyota, criticized them as being too basic a tool to analyze root causes to the depth that is needed to ensure that they are fixed. Reasons for this criticism include:
• Tendency for investigators to stop at symptoms rather than going on to lower-level root causes.
