The diagram does not differentiate the major and minor defects based on their severity.

It has been identified that a product that passed through quality control has had issues. To overcome this, the root cause of the issue has to be analyzed.

Fix the Issue

All supplies and resources used in the production or process are reviewed to determine their effect.

It is a visual quality management tool that provides an overall list of possible causes to determine the root cause of a specific event. It helps to understand what causes a problem and what are the possible ways to solve it. To help find the ultimate root cause from all the ideas gathered, a voting technique would solve the problem by having the team members to identify top three major root causes. One can use sticky notes or colored to flags to mark the three major causes.
