Summary

Milestone tasks in Microsoft Project are defined as any tasks with a duration equal to zero or a value of Yes in the Milestone field.

More information

In general, a milestone is a task that represents a significant date in a project, such as the completion of a project phase, or the date a particular report is due.

For Microsoft Project to be aware that a particular task is a milestone, its Milestone field must be set to Yes. Microsoft Project sets this value to Yes automatically for any tasks you enter with a duration of zero. To create milestones out of nonzero duration tasks, use the method appropriate for your version of Microsoft Project.


Microsoft Project 2010 and later

  1. On the view tab, click a task view, such as Gantt Chart or Task Sheet.
  2. Select the task you want to flag as a milestone.
  3. On the Task tab, click Information button on the Properties section of the ribbon.
  4. Click the Advanced tab and place a check mark in the "Mark task as milestone" check box.
  5. Click OK.
