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.

As our author explains, the S-curve is simply a matter of counting observations and plotting them against time. However, relatively few project activities are conducive to this type of approach. Nevertheless, over a period of multiple related activities, it is possible to make informed assessments of work completed and plot these in the same way. The resulting graphic is a much better way of understanding the state of the project and reporting that to management. It should be included in management reports as a matter of standard practice.

Introduction

The first time most project managers become aware of the existence of S‑curves is when they are requested by their client or senior management to include S‑curves in their next progress report. The purpose of this White Paper is to explain what S‑curves are, how they are generated, why it is an important Project Management tool, and how to use S‑curves to analyze a Project.
