The first time most project managers become aware of the existence of S-curves is when they are requested by the client or senior management to include one in their next progress report. The following explains what the mysterious S-curve is, why it is an important project management tool, and how to generate one.

Editor's Note:

The S-curve is a powerful project management control tool. Why it is the shape it is, how to use it and "Max's Rule of Thumb" for drawing it as a part of the project planning activity are all described in Chapter 10 of A Management Framework for Project, Program and Portfolio Integration. You can also find more information on this web site by entering "S-curve" or "Resource loading" into the site search engine field.
