Critical Chain Project Management, an innovative method to successfully finish its project, on time, within budget and conform to customer's specifications.

Overview

 

Most of the projects traditionally managed with the Critical Path Method (CPM) or the Program Evaluation and Review Technique (PERT) suffer from time and budget overruns of 50 to 200% and often original specifications have to be abandoned.

Critical Chain Project Management (CCPM) has shown for more than 10 years, that performances can be significantly improved applying this new approach.

The Critical Chain is defined by the longuest chain of dependencies between tasks, taking into account critical resources conflicts. The management must focus on the Critical Chain. Critical Chain is different from traditional critical path :

  • We use  a new way to estimate tasks durations,  which theoretically allows a 50% tasks durations reduction,

  • The project is protected from hazards thanks to a project buffer (this buffer is calculated from the reduction of individual safety on each task),

  • Feeding buffers are inserted to protect the Critical Chain from delays on non-critical tasks,

  • The project, or projects in multi-projects environments, are managed according to new evaluation cirteria, the critical/ non-critical dual view, and the buffers monitoring, allowing management to be more proactive and reactive, 

  • We prevent resources on the Critical Chain from multitasking,

  • We minimize the "Student syndrom" (to postpone until the last moment working on a task) by valuing tasks finished in advance, 

  • Warnings are used for resources working on the Critical Chain and this way, they can get ready to work on their part of the project.

Critical Chain Project Management allows projects to be finished on time, within budget and without compromises on customer's original specifications. Moreover, we notice an increase in projects performances, an increase in resources productivity and a better and more serene working environment.
