CPM Mechanics:

The Critical Path Method of Modeling Project Execution Strategy

ICS-Compendium Dominant Series: Volume 1

Cover01CPM Mechanics is the first volume of the ICS-Compendium to be written and published — and for a very good reason. Everything depends on one’s understanding of the basics of the Critical Path Method, at its functional core

How the Critical Path Method Works

The limited scope of CPM Mechanics is to fully explain every aspect of how the Critical Path Method works “under the hood.” Left for another ICS-Compendium text (Volume 3) is how to apply the CPM technology discussed in this volume  — so as to design, develop, and maintain an actual Critical Path Schedule.

The goal of this book, quite possibly the best project management book on the Critical Path Method, is to teach the underlying science behind the Critical Path Method. While the subject matter may seem a bit dry and technical, its full understanding is essential to any subsequent use of the information derived from a CPM-based schedule.

Such usage would include Critical Path Method (CPM) Analysis, delay analysis, Earned Value’s Schedule Performance Index (SPI) or Schedule Variance (SV), CPM’s Total Float and Free Float, and so forth.

So before you tackle the question, “What is CPM scheduling?” make sure you can fully answer this question: “What is the Critical Path Method and how does it work?”
