The Processes are activities and procedures followed by an organization team to create a product, i.e., the work the organization does, or a statement of “what we plan to do”.
Plan activities are statements of the work to do, including precedence relationships among activities, and scheduled activities have a planned start and end.
Activities have responsible actors; they may have coordination and rework dependencies that identify the other activities with which they must coordinate or that must initiate rework if an individual activity encounters some sort of failure.
POP models represent the Functions, Forms, and Behaviors of project Processes.
