project milestones

Key completion points

Project milestones are significant checkpoints or target dates within a larger undertaking that mark the completion of major phases or deliverables.

They serve as reference points for measuring progress and keeping work on schedule: We celebrated reaching the first project milestone ahead of deadline.

Unlike regular tasks, milestones typically have no duration themselves—they simply mark that a critical threshold has been crossed.

Teams use them to coordinate handoffs, trigger payments, or signal readiness for the next phase.
