Just as projects are unique, so are project management plans. A small project that involves a few people working over a couple of months might have a project management plan consisting of only a project charter, scope statement, and Gantt chart. A large project that involves $100$ people working over three years would have a much more detailed project management plan. It is important to tailor project management plans to fit the needs of specific projects. The project management plans should guide the work, so they should be only as detailed as needed for each project.

Most project management plans have common elements. A project management plan includes an introduction or overview of the project, a description of how the project is organized, the management and technical processes used on the project, and sections de$-$ scribing the work to be performed, the schedule, and the budget.
