What are the two most important actions to take with formal and informal change performance...

Feedback is valuable only if it isshared and acted upon. ACMP directs that performance feedback should be:

Shared with project leadershipto enable decision-making and corrective action.

Incorporated into future change management activitiesto continuously improve.While stakeholder sharing (B and C) may be appropriate, the critical accountability lies with leadership and the improvement of change practices. Option D reflects this continuous improvement cycle, making it the most aligned answer.(Reference: ACMP Standard, Process Group 4 – Execute; Activity: Capture, analyze, and integrate feedback into current and future change activities.)
