Milestones

A milestone is a named goal tasks can belong to. A milestone bar on a timeline is a marker on the chart. ProjectBrain keeps the two linked.

“Milestone” means two things in ProjectBrain:

  • A milestone is a named goal, such as “Beta launch”, that tasks can be assigned to.
  • A milestone bar is an entry on a project’s timeline with the entry type milestone. It marks a date on the chart.

When you add a milestone bar to a timeline, ProjectBrain creates a matching milestone and links them. So the chart and the task picker show one list, not two.

  1. Open the task.
  2. Choose Milestone.
  3. Pick a milestone, or type a new name and choose Create milestone.

To see everything in a milestone, open it from a task and choose See every task in this milestone.

  1. Open the project’s Timeline tab and choose Add Entry.
  2. Set Entry Type to milestone and give it a date.
  3. Choose Add Timeline Entry.

A matching milestone now appears in the task picker. To group other timeline entries under it, use Group under a milestone when you add or edit them.

  • Changing a milestone bar to another entry type unlinks it. The milestone itself stays, and so do the tasks in it.
  • Deleting a milestone bar does not delete the milestone.
  • A group row on the timeline cannot be a milestone.
  • AI tools connected to ProjectBrain can create and update milestones. They cannot delete them.
