See Appendix J if you need a refresher on milestone trend charts. Chapter 38 also has some specific applications of milestone trend charts. Figure 7-3 is the preferred way to track progress in a Rapid Development Waterfall project.

This project has three concurrent swim lanes that may have cross–swim lane dependencies. Milestone trend charts do not show any cross–swim lane dependencies, but that does not compromise the usefulness of the charts. In this case, for example, the first three panels show the status of each swim lane with respect to completing on schedule. The fourth panel shows the status of all the swim lanes with respect to being completed on schedule. Looking at Figure 7-3, you can see that Swim Lane A has slowly drifted behind schedule and is now two weeks behind schedule. Because it has two weeks of slack in its schedule, it has exceeded that and placed the project one week late. Swim Lane B, which is on the critical path, has returned to on-schedule status as of the most recent report date. Its completion drives the beginning of the integration test activities. ...
