When a proposed change could potentially enhance delivery value or improve testing efficiency, the best practice is to assess the impact on scope, schedule, and stakeholder expectations before making a decision. The PMBOK Guide encourages evaluating change requests for their implications. Option C reflects this by not outright rejecting the proposal, but rather responsibly assessing its impact. Option A may bring in stakeholders too early before the impact is known. Option B is rigid and may ignore potential benefits. Option D logs an issue prematurely before the impact is clear.
