How do you define a milestone?

A milestone in project management is a significant event or achievement that marks progress within a project’s timeline. It serves as a point of reference to gauge how well a project is progressing towards its goals and objectives. Milestones are typically identified during project planning and are strategically placed at key stages or phases of the project. They are used to track progress, communicate achievements, and ensure alignment with project objectives. Milestones are often associated with specific deliverables, deadlines, or accomplishments and are essential for keeping the project on track, managing stakeholder expectations, and celebrating accomplishments along the way.
