What is root cause analysis?

• A. A quick fix for immediate problems.
• B. A systematic method to identify underlying causes of a problem and implement preventive actions.
• C. A method for diagnosing patient symptoms.
• D. A process to assign blame.

Answer: (B)

Root cause analysis is a structured process used to uncover the underlying factors that lead to a problem, so you can put in place actions that prevent it from happening again. It goes beyond fixing the immediate symptom and asks why the problem occurred in the first place, often using step-by-step methods like asking “why” multiple times or drawing a diagram of contributing factors to map out people, processes, equipment, and environment. In practice, it means gathering data, testing hypotheses about cause-and-effect, and implementing corrective and preventive actions (CAPA) with follow-up to verify effectiveness. This is why the best answer describes a systematic method to identify underlying causes and implement preventive actions. It isn’t about quick fixes that only address the surface issue, diagnosing a patient’s symptoms, or assigning blame.
