Why is it important to assess the communication needs of different stakeholder groups?

Assessing communication needs ensures effective messaging in SAP OCM. Option C is correct because it prevents under- or over-communication, maintaining engagement without overwhelming stakeholders. Option D is correct as tailoring information (e.g., by role or impact) increases relevance and adoption. Option A is incorrect—stakeholder identification precedes communication planning, not vice versa. Option B is also incorrect; change impacts are assessed separately, not primarily through communication needs.
