Milestone Schedule — definition
Summary schedule identifying key project dates and deliverables, such as design approval, factory acceptance, delivery and commissioning, used for high-level tracking.
A milestone schedule is typically derived from the detailed critical path schedule but presents only significant checkpoints for reporting to sponsors, lenders or steering committees. It provides a simplified view of project progress without the full detail of the underlying activity-level schedule.
Why it matters to industrial buyers
A concise milestone schedule allows non-technical stakeholders, including financiers, to track project progress without needing to interpret a detailed activity-level schedule.
