Which advice fosters a successful delivery of change effectiveness activities?

Change effectiveness in SAP OCM assesses impact through metrics. Option B is correct because a mix of metrics (e.g., adoption rates, satisfaction) ensures comprehensive evaluation. Option A is incorrect—open communication may help but isn’t specific to effectiveness delivery. Option C is incorrect; lessons learned should be routine, not conditional. Option D is impractical—ROI for OCM is hard to quantify precisely.
