This would really depend on what your milestones are. Are you tracking milestones by a projects state? If so, making a report based off that state field would be most advantageous.
Can you provide an example of a typical project your organization utilizes? If so, I can help build a decent starter report for it. It'd be helpful also to include any approval workflows or other process diagrams associated with your projects.
If I've at all helped, please return the favor by clicking the thumb next to my post. Thanks!
