  1. The Merits and Pitfalls of Critical Chain Scheduling Oya I. Tukel, Ph. D.

  2. 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

  3. 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

  4. 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

  5. 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

  6. An Example Three paths, nine tasks and six resources

  7. Late start schedule

  8. Resource Conflicts Eliminate resource contentions, blue and orange

  9. Resolve Contentions Add two artificial precedence relations

  10. Determine Critical Chain

  11. Insert Feeding Buffers

  12. Insert Project Buffer

  13. Buffer Size • Cut and Paste Method • Root Square Error Method • Monte Carlo Simulation Method
