Project Milestone: A marker in time, usually indicating a the completion of a project task.
Project milestones offer a place in time to stop and analyze your progress. Have you completed the tasks you had planned? Is your project on track?
Project milestones are normally project tasks with zero-duration work. That is to say, no work is expected for such a task, except to stop and monitor your current progress. They often display in a Gantt chart with a diamond shape to indicate that stopping point.
