Plan the Process
Requirements for the process's specified work products and for performing the work may be derived from other requirements. In the case of a project’s processes, they may come from that project’s requirements management process; in the case of an process, they may come from organizational sources.

The objectives for the process may be derived from other plans (e.g., the project plans). Included are objectives for the specific situation, including quality, cost, and schedule objectives. For example, an objective might be to reduce the cost of performing a process for this implementation over the previous implementation.

Establishing a plan includes documenting the plan and providing a process description. Maintaining the plan includes changing it as necessary, in response to either corrective actions or to changes in requirements and objectives for the process.
