It builds upon earlier techniques such as earned value management, critical path method, and program evaluation and review technique, but uses these to track and index projected project profitability as well as the more traditional cost and schedule.
Introduced with TPC are a variety of project management metrics and techniques, among them critical path drag,[2][3] the value breakdown structure (VBS), Devaux's Index of Project Performance (the DIPP),[4] Doubled Resource Estimated Duration (DRED), and Cost of Leveling with Unresolved Bottlenecks (CLUB).
"[6] He also wrote: "Tools and practices for managing projects and programs as investments have been defined... For example, critical path drag is a concept for evaluating how much any activity along the critical path can be shortened to optimize the project duration.
"[7] Since the total project control approach was introduced in the first edition of Devaux's 1999 book by that title, others have extended both the theory and the practice.
In 2013, Tomoichi Sato of JGC Corporation in Yokohama suggested an "extended DIPP" based on risk-based project value.
