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.

What are 5 Whys in Six Sigma?
The 5 Whys is
a basic root cause analysis technique
used in the Analyze phase of the Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control). To solve a problem, we need to identify the root cause and then eliminating it.

. The Six Sigma expert uses qualitative and quantitative techniques to drive process improvement.
How do you do a 5y analysis?
The method is remarkably simple: when a problem occurs, you
drill down to its root cause
by asking “Why?” five times. Then, when a counter-measure becomes apparent, you follow it through to prevent the issue from recurring.
What is the purpose of 5 Why analysis?
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.
