Milestone slip charts (and other names such as milestone trackers) could help track key milestones in an agile project. The idea is that on a regular basis the project manager forecasts when the milestones will be met.
Because of scrum, you may not want to track features as they move according to business priorities. So what is left is milestones that won’t change because of business priorities. Let’s look at some examples:
1. Minimum Viable Product: scope of this milestone may change because of business priorities but the Minimum Viable product by itself will not change priority: you need one.
2. First run on production: whether this is one story or more, they need to run in the product environment meeting acceptable KPI(s).
3. Initial performance testing…
4. First release to external customers…
5. End of project (whether this is scope or date driven)
6. Start of Sprint 1
7. Stable velocity (normally within 3 sprints)
You can even follow Agile SDLC: Envision, Speculate, Explorer, Adapt and Close.
