What is the purpose of incident investigation and what is a common root-cause analysis technique?

• A. To determine how and why an incident occurred and to prevent recurrence; commonly used technique is the Five Whys or Root Cause Analysis.
• B. To assign blame to workers; technique: Pareto chart.
• C. To document regulatory requirements.
• D. To punish unsatisfied participants; technique: SWOT.

Answer: (A)

The purpose of incident investigation is to determine how and why an incident happened and to prevent it from happening again. A common root-cause analysis technique is the Five Whys, which involves repeatedly asking why a problem occurred to drill down to the underlying root cause and identify corrective actions. This approach focuses on learning and fixing system, process, equipment, or human factors rather than blaming people. It helps you uncover underlying conditions that allowed the incident to occur and guides improvements to prevent recurrence. Other options miss the goal: assigning blame isn’t the aim of a constructive investigation; a Pareto chart is a tool for prioritizing issues, not uncovering root causes; documenting regulatory requirements is about compliance, not the investigative purpose; punishing participants is inappropriate and harms safety culture; and SWOT is a strategic analysis method, not a technique for root-cause analysis.
