How to Set Milestones in Project 2013
Milestones are signposts that mark significant events in Project 2013. Examples of milestones are the approval of a prototype (although the deliberations to make that decision might have taken months), the completion of a key deliverable, or the start or end of a project phase.
Some people include tasks such as Design Completed or Testing Completed at the end of each phase of their projects (incorporating the leading practice of using the past-tense noun-verb naming convention).
They can then create timing relationships to the moment of completion in Project 2013— for example, allowing the production of a drug to proceed after the testing and approval is complete. Such milestones also alert you and your team members to a moment of progress in your project that can help keep the team motivated.
New tasks are created with an estimated duration of one day unless you enter a duration. To create a milestone in Project 2013, you indicate that the task has zero duration.
The quickest way to do it is to simply type 0 in the Duration column in Gantt Chart view. Or you can click the Advanced tab in the Task Information dialog box and select the Mark Task As Milestone check box.
When you do, the milestone is designated in Gantt Chart view with a diamond shape rather than a task bar. Use this latter method for any milestone that has a duration other than zero but that you want to mark as a milestone anyway; its milestone marker is charted at the end of the duration period on the Gantt chart.
