Project Communication Management is the knowledge area that covers the processes required to ensure timely and appropriate generation, collection, distribution, storage, retrieval, and ultimate disposition of project information. It involves planning, managing, monitoring, and controlling the communication activities and deliverables throughout the project lifecycle.
