This chapter describes the model processes related to project communication and reviews basic concepts related to human-to-human relationships. Communication is the fuel that drives project success and the mishandling of this activity is one of the top reasons why projects struggle. Effective communication is required between the project manager, the project team, management, and other stakeholders. An environment that achieves effective communication among this diverse group will find an improved outlook for project success. Some of the basic activities include interacting with diverse audiences, holding effective meetings, and facilitating communication among external parties involved in the project. The knowledge areas of Project Communications Management include the processes required to ensure timely and appropriate generation, collection, distribution, storage, retrieval, and ultimate disposition of project information. A vital foundation component in the successful management and completion of a project is the creation and implementation of a communications plan at the start of a project.
