What action verifies the effectiveness of corrective actions after an incident investigation?

• A. Effectiveness checks.
• B. End-of-year review.
• C. Cancel action.
• D. No follow-up.

Answer: (A)

After an incident investigation, you must confirm that the corrective actions actually work and reduce the risk. This verification is done through effectiveness checks, which are follow-up evaluations that look for evidence the actions achieved their intended outcome. This means gathering data, observing processes, and testing controls to ensure the root cause was addressed and the risk of recurrence has decreased. For example, you might monitor relevant performance indicators, conduct audits or re-tests, and review incident trends after the actions are in place to see if there’s an improvement.

End-of-year reviews come too late to confirm current effectiveness, and canceling the actions avoids fixing the issue. No follow-up leaves the outcome unverified and risk unmeasured, leaving potential problems unresolved.
