Introducing a new PMO service requires a detailed communications management plan to ensure that all stakeholders are informed, engaged, and prepared for the change. PMI-PMOCP outlines the importance of formal communication planning to manage expectations, promote the new service, and facilitate successful adoption. While discussions (option A) and feedback collection (option B) support content quality, they do not address stakeholder awareness and acceptance. Sharing details only at executive meetings (option D) limits the communication reach. A structured plan ensures consistent, clear messaging to all relevant parties.
