The conference

Most projects managed traditionally with the Critical Path Method or the Program Evaluation and Review Technique (PERT) suffer from time and budget overruns and often original specifications have to be abandoned. Critical Chain Project Management (CCPM) has shown for more than 15 years that performances can be significantly improved by applying this new approach.


  • The Critical Chain is defined by the longest chain of dependencies between tasks, taking into account critical resources conflicts. But the “Critical Chain Way” is much more than this limited definition.
  • CCPM can be used both for individual projects large or small or portfolios of projects.
  • A different technique for estimating task durations is used (average/aggressive plus pessimistic).
  • The project is protected from uncertainty and problems thanks to a project buffer (safeties are removed from individual tasks).
  • Feeding buffers are inserted to protect the Critical Chain from delays on non-critical tasks.
  • The “Fever Chart” is used to manage execution. It provides real time identification of task priorities.
  • Multitasking, which is considered one of the main killers of performance, is minimized.
  • The "Student syndrome" (to postpone until the last moment working on a task) is addressed.
  • Etc.

This approach first appeared at the end of the 90s. Today it is used quite extensively throughout the world. Over 500 companies have implemented it including: Mazda, Siemens, Embraer, Procter & Gamble, Louis Vuitton, Safran, Boeing, Lilly and the United States armed forces. Critical Chain Project Management allows projects to be finished on time, within budget and without compromises on original specifications. Moreover, CCPM has shown that: it reduces project durations by over 40%; increases resource productivity and significantly improves the working environment.
