Creating Milestone Tasks

Project milestones are used to mark a point in your project, usually completion of a set of tasks or as a project health check to determine if you’re on schedule.

When creating a milestone task, you cannot assign a resource, enter estimated work, or a Finish No Later Than (FNLT) constraint. When viewing a project Gantt chart or schedule, milestone tasks are differentiated from regular project tasks.

To create a project milestone:

  1. Go to Lists > Relationships > Projects.

  2. Click the name of the project you want to edit.

  3. On the Schedule tab, click New Milestone.

  4. Enter a name for your milestone.

  5. Click the Predecessors tab.

  6. Select a predecessor task and type.

  7. Click Add.

  8. Continue adding any additional predecessors, when you have finished, click Save.

Converting Milestone Tasks to Project Tasks

A milestone can be converted to a project task by adding a positive number of estimated work or tracking time against the milestone.


You can edit a milestone and assign a resource with 0 hours of estimated work without converting the milestone to a project task. However, if the resource tracks time against the milestone it will be converted to a project task.

A Project task can also be converted to a milestone by removing positive estimated work and any FNLT constraint.
