The Merits and Pitfalls of Critical Chain Scheduling Oya I. Tukel, Ph. D.
Fundamentals of Critical Chain Scheduling • Critical Chain by Goldratt, 1997 • Claimed to be the most important breakthrough in project management since the development of critical path
Resources • Project Management in the Fast Lane, Newbold, 1998. • Critical Chain Project Management, Leach, 2000. • Articles: Cabanis-Brewin, 1999; Globerson, 2000; Pinto, 1999. • Web pages: www.pdinstitute.com www.prochain.com
Resources www.focusedperformance.com • Book reviews: Elton and Roe, 1998; McKay and Morton, 1998; • Letters to the editor in Project Management Journal and PM Network
Steps in Critical Chain • Develop late start schedule using average task durations • Eliminate resource contentions • Identify critical chain(s) • Insert feeding buffers • Insert project buffer
An Example Three paths, nine tasks and six resources
Resource Conflicts Eliminate resource contentions, blue and orange
Resolve Contentions Add two artificial precedence relations
Buffer Size • Cut and Paste Method • Root Square Error Method • Monte Carlo Simulation Method
