This document outlines 10 key features of Microsoft Project plans (MPP). It discusses setting up the project calendar and holidays; adding tasks and milestones; setting task constraints and dependencies; assigning resources and resource rates; tracking resource usage and leveling; setting a project baseline; measuring progress using a Gantt chart; and generating reports on milestones. The overall purpose of a project plan is to define tasks, timelines, resources, risks, stakeholder commitments, and provide a framework for review and control to deliver the project on time and within budget.
