    Definition

    What is Milestone?

    A milestone is a significant checkpoint in a project that marks the completion of a phase or a key deliverable, used to measure progress against the plan.

    A milestone is a marker, not a task. It has no duration: it is a moment that signals something important has been reached, such as "design approved" or "beta launched." Milestones give a project a sense of progress and rhythm.

    Milestones are useful for communication and control: they let stakeholders track high-level progress without following every task, and they are natural points to review, get sign-off, or adjust the plan.

    Atlas lets teams set milestones on project timelines, so major checkpoints are visible alongside the tasks that lead up to them.

    FAQ

    Questions, answered.

    What is the difference between a milestone and a task?
    A task is work with a duration that someone does. A milestone is a zero-duration checkpoint marking that a phase or deliverable is complete: a marker of progress, not work itself.
    Why use milestones in a project?
    Milestones communicate high-level progress, provide natural review and sign-off points, and help stakeholders track a project without following every individual task.
