Explain the role of incident investigation in continuous improvement.

• A. Assigns blame to individuals and stops at documenting.
• B. Determines root causes, identifies corrective actions, and informs system improvements to prevent recurrence.
• C. Delays corrective actions while costs are evaluated.
• D. Only records the incident for regulatory compliance.

Answer: (B)

Investigating incidents drives continuous improvement by uncovering root causes, outlining corrective actions, and feeding system changes to prevent recurrence. A good investigation goes beyond what happened to why it happened, examining technical failures, human factors, and organizational weaknesses. By identifying root causes, it guides actions that fix the underlying issues—such as redesigning processes, updating procedures, improving training, or enhancing controls. When those actions are implemented and verified, they break the cycle of repeated incidents and promote healthier, safer operations.

Accepting blame or stopping at documentation doesn’t push the system forward, because it focuses on individuals rather than system weaknesses. Waiting to act while weighing costs delays learning and preserves risk. Merely recording incidents for regulatory purposes misses the opportunity to learn and improve.
