What are the key steps in conducting a root cause analysis after an incident?

• A. Gather evidence, reconstruct events, identify underlying causes, develop corrective actions.
• B. Identify only the immediate cause and implement a quick fix.
• C. Assign blame to the nearest supervisor.
• D. Gather evidence, reconstruct events, identify underlying causes (systemic vs human error), develop corrective actions, and verify effectiveness.

Answer: (D)

Root cause analysis after an incident aims to determine why it happened and how to prevent it from recurring by addressing the underlying factors, not just the immediate symptom. The strongest approach starts with gathering evidence and reconstructing the sequence of events to have a clear picture of what occurred. It then goes deeper to identify underlying causes, explicitly distinguishing between systemic factors and human error, so the investigation targets the real drivers of the incident. After pinpointing these root causes, it develops corrective actions designed to remove or reduce those factors and prevent recurrence. Finally, it verifies the effectiveness of those actions, checking that the changes work in practice and are sustainable before closing the investigation. This approach is superior because it moves beyond quick fixes or blame, ensuring that improvements address the true causes and that improvements are actually working over time.
