The official business definition of a Project Milestone Schedule is a document that outlines the major milestones of a project, which serve as checkpoints for the project’s progress. It is used to ensure that the project is on track and to enable team members to assess the work completed so far. The Project Milestone Schedule typically includes the date when the milestone is expected to be achieved, as well as any associated deliverables, tasks, or activities that must be completed to reach the milestone. It also includes any resources needed to achieve the milestone, such as labor, materials, or equipment, and any deadlines associated with the milestone. In addition, the Project Milestone Schedule typically includes a description of the milestone, which helps the team to better align their efforts and identify any potential obstacles in the project.
