The terms "planning" and "scheduling" have different meanings. A project plan is a formal, approved document used to guide both project execution and project control. The primary uses of the project plan are to document planning assumptions and decisions, facilitate communication, and to document the approved scope, cost, and schedule baselines; these baselines serve as the foundation to measure progress and track changes. A project schedule is an essential part of any project plan. A schedule provides the details about the activities that must be done, when they must be done, who is doing the work, and work progress measurement criteria. The terms "task" and "activity" are used interchangeably to describe the work unit that must be completed to reach the end objective of the project.
