Why should feedback mechanisms be used to monitor performance of a change management plan?

Feedback mechanisms (surveys, focus groups, one-on-one sessions) serve as amonitoring toolto ensure the change plan is working as intended. According to ACMP, they provide actionable information that allows the change team todevelop responses to emerging challenges and adjust the plan. Options B, C, and D are outcomes of feedback but not the fundamental reason for using feedback mechanisms. The core purpose is option A — to monitor effectiveness and adjust accordingly.
