What is the 5 Why method of problem solving?
The 5 Whys Problem Solving technique is a simple process to follow to solve any problem by repeatedly asking the question “Why” (five times is a good rule of thumb), to peel away the layers of symptoms that can lead to the root cause of a problem. This strategy relates to the principle of systematic problem solving.
What is a 5 Whys diagram?
The 5 Whys and fishbone diagrams help practices identify obstacles to good performance and what causes them. They can also be used to identify the factors contributing to exemplary performance in order to replicate them.
When should the 5 Whys be used?
Use the five whys technique when you want to push a team investigating a problem to delve into more details of the root causes. The five whys can be used with brainstorming or the cause-and-effect diagram. Use the five hows technique to develop more details of a solution to a problem under consideration.

What are 5 Whys in Six Sigma?

Once a cause is identified, its root cause is explored with the 5 Whys technique. By simply asking ‘why’ multiple times, the cause of the previous cause is uncovered, and added to the diagram.

What is a why diagram?
A Why-Why Diagram is a Tree Diagram where each child statement is determined simply by asking ‘why’ the parent occurs, as below.

What is the purpose of why analysis?
What is the purpose of a why-why analysis? A why-why is conducted to identify solutions to a problem that address it’s root cause(s). Rather than taking actions that are merely band-aids, a why-why helps you identify how to really prevent the issue from happening again.
