What is the purpose of the fishbone diagram?
A . To brainstorm solutions to problems
B. To identify improvement backlog items
C. To identify potential root causes to problems
D. To identify the biggest root cause

Answer: C

Explanation:

A fishbone diagram is a visual way to look at cause and effect and used to identify potential root cause. It is a more structured approach than some other tools available for brainstorming causes of a problem (e.g., the Five Whys tool). The problem or effect is displayed at the head or mouth of the fish.
