Milestones

Milestones are zero-day activities that call attention to noteworthy events in a project schedule. They may indicate either the start or completion of a significant series of events.

• You can add a milestone task from the Add option on the Interactive Gantt or by setting the duration of the task as 0d.
• When you assign resources to this task, the allocation will automatically be pre-filled by 0%.
•  A milestone has 0 duration and as such has no additional calculation effect on the schedule. 
• A milestone can be linked to other tasks. 
• You can set constraint dates on a milestone.
•  Milestones are not shown on the Resource Load Chart.
