Plan schedule management is a process in the PMI process group of planning and the PMI knowledge area of time management. It involves planning how the project's schedule will be created and maintained.

According to the PMBOK, this activity has the following characteristics:

Inputs Tools and Templates Outputs
project management plan, project charter, enterprise environmental factors, organizational process assets expert judgment, analytical techniques, meetings schedule management plan


The project management plan provides the scope baseline, especially the WBS. It also provides other information such as when communications, costs, or risks may impact the schedule. The project charter provides the high-level milestones and the approvals. Enterprise environmental factors and organizational process assets provide other guidelines and constraints that could affect the schedule. Some examples are when required management approval meetings are held, company holidays, historical information about how long previous projects took for similar activities. In addition, the organizational process assets may include previous schedule management plans or templates.

Tools and TechniquesEdit

Like several other planning processes, expert judgment and meetings are useful in planning the schedule management. The analytical techniques for schedule management include the use of scheduling tools and schedule analysis techniques including rolling wave planning, leads and lags, alternatives analysis, critical path analysis and others. (See the other time management processes for more about the tools and techniques.) The schedule management plan may identify which tools and techniques will be used; however, those tools are not actually used in planning the schedule management.


The output created by the plan schedule management process is the schedule management plan. It is part of or subsidiary to the project management plan.
