In my projects I have different milestones, like end of phases, documents or reports to deliver. I insert them as such in  the project and I use the Milestones Report to know the upcoming ones and review the achived ones. For this Microsoft Project provides me  with a Milestones Report and you can learn how to use it in this video.

The timeline in Microsoft Project is a powerful communication tool that will greatly help a project manager in its communication with teams, stakeholders or reporting on his project. When you understand how to use it, you will improve your project presentations.
