Root Cause Analysis (RCA) is a popular and often-used technique that helps people answer the question of why the problem occurred in the first place.

The 5 Whys method helps your team focus on finding the root cause of any problem. It encourages each team member to share ideas for continuous improvement, rather than blaming others. It gives your team the confidence that it can eliminate any problem and prevent the process from recurring failures.

During investigation, it may occur, that you find out, there is no non confirmity. In contrast, in root cause analysis, you try to find the really root cause of the problem environment reconstructed during the investigation.

A Cause-and-Effect Diagram is a tool that helps identify, sort, and display possible causes of a specific problem or quality characteristic (Viewgraph 1). It graphically illustrates the relationship between a given outcome and all the factors that influence the outcome.

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?".

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.

Remember number '5' in 5-Whys is not some hard-and-fast rule, rather it's arbitrary. The idea is to go deeper until the last layer of the problem, until you see the root cause. Therefore, you may have to ask four, six, or seven whys before you can unravel the core issue of any problem.
