1. Mastery of the Critical Path Method (CPM) This is the book's strongest selling point. Stephenson doesn't just explain what CPM is; he explains how to build a functional network diagram from the ground up. He covers the nuances of:
2. The "Paper-and-Pencil" Foundation In an era where most scheduling is done via software (Primavera P6, MS Project), Stephenson insists on teaching the manual calculations first. This is vital because software users often become "button pushers" who accept default settings without understanding the logic.
3. Claims and Delay Analysis For professionals involved in forensic scheduling or claims work, this book is an essential resource. It provides detailed methodologies for analyzing delays, determining responsibility, and using "As-Built" vs. "As-Planned" schedules to settle disputes. It is frequently cited in construction litigation. bar charts (Gantt charts)
4. Visual Learning The text is packed with network diagrams, bar charts (Gantt charts), and logic tables. The visual progression from a simple activity list to a complex network diagram is handled exceptionally well.
Stephenson distinguishes "planning" from "scheduling." Planning is defined as the mental or conceptual process of determining what needs to be done and how it will be accomplished. bar charts (Gantt charts)
Scheduling is the translation of the plan into a time-based format.
If you manage to get your hands on a copy (physical or digital), here are the four key technical areas you must master. bar charts (Gantt charts)
Before a single schedule is drawn, Stephenson emphasizes strategic planning. This involves:
This is perhaps the most valuable section for contractors. Stephenson explains how to calculate the cost slope of an activity. If you want to finish a project 10 days early, which activities do you accelerate? The cheapest ones. He provides tables and formulas for "Crashing" a network without bankrupting the job.
