How to set milestones:
1. Big picture: You’re figuring out how to get from start to finish
2. Brainstorm the steps you need to take to complete your project. Don’t worry about getting every last one — focus instead on big steps that are essential for the completion of the project.
3. Examine your list of steps. Are there any that are clearly concrete and have a clear end point? For example, if you were building a house then “all of the floors installed” is a concrete step that has a clear finish point.
4. Pick the concrete steps with clear finish points and name them as your milestones. When you’re writing out the milestone, however, make sure they don’t sound like a task.
“Milestones should have a clear description of your project schedule, but not one that implies they are a task. So they shouldn’t be called ‘Get agreement to move into Phase 2’ but ‘Phase 2 starts’. If you want to reflect the effort of getting agreement to move into Phase 2 then add a task in just before that says that.”
