What is a Milestone in Project Management?
A milestone is a specific point in time within a project lifecycle used to measure the progress of a project toward its ultimate goal. In project management, milestones are used as signal posts for: a project's start or end date, a need for external review or input, a need for budget checks, submission of a major deliverable, and much more. Milestones have a fixed date but no duration. So what is a milestone in project management? Simply put, it's a reference point that marks a major event or a branching decision point within a project.
