What is the purpose of a root cause analysis?

• A. A systematic examination to identify underlying causes of a problem.
• B. A method for rapid brainstorming of solutions.
• C. A process for documenting project milestones.
• D. A summary of project outputs.

Answer: (A)

The main idea behind root cause analysis is to drill down into a problem to find its fundamental causes, rather than just treating the obvious symptoms. By systematically exploring why the problem occurred, you identify underlying factors that, once fixed, reduce the chance of it recurring. This often uses structured methods like repeatedly asking why or mapping out causes and effects to reveal relationships and contributing conditions. The goal is to implement solutions that address those root causes, leading to lasting improvements. The other options describe processes not about diagnosing causes: rapid brainstorming focuses on generating solutions, documenting milestones tracks progress, and summarizing outputs reports results.
