Why is it important to include verification of corrective actions in the investigation plan?

• A. To confirm that actions were implemented as planned and effectively mitigate risk.
• B. To confirm that actions were implemented correctly and that they effectively mitigate risk or prevent recurrence, ensuring accountability.
• C. To document the time of day actions were done.
• D. To assign blame for the incident.

Answer: (B)

Verification of corrective actions focuses on confirming that the fixes were put in place as intended and actually reduce the chance of recurrence. This step closes the loop after an investigation by testing and validating that the actions address the root causes and mitigate the identified risks, not just exist on paper. It also establishes accountability, providing evidence about who implemented and checked the actions and when, which supports learning and governance. Actions that only document implementation or blame targets miss the core purpose, which is ensuring real effectiveness and responsible ownership.
