Which of the following is MOST important for a risk practitioner to confirm once a risk action plan has been completed?

Updating the risk register is an administrative task that should happen, but it is secondary to confirming the actual mitigation effectiveness.

Recalibrating risk tolerance is a strategic decision and not a direct consequence or confirmation of a completed risk action plan; tolerance is set for broader organizational context.

The primary objective of a risk action plan is to reduce a specific risk to an acceptable, targeted level. Therefore, the most critical confirmation for a risk practitioner is to verify through monitoring and assessment that the implemented actions have indeed achieved this intended reduction, ensuring the plan was effective.

The risk owner reviewing outcomes is important for accountability and awareness, but the practitioner's technical confirmation of actual risk reduction is more fundamental to the success of the plan itself.
