Critical chain project management (CCPM) is a method of planning and managing projects that puts the main emphasis on the resources required to execute project tasks. It was developed by Eliyahu M. Goldratt. This is in contrast to the more traditional critical path and PERT methods, which emphasize task order and rigid scheduling.

From the Wikipedia Article on Critical Chain Project Management:

Critical chain project management (CCPM) is a method of planning and managing projects that puts the main emphasis on the resources required to execute project tasks. It was developed by Eliyahu M. Goldratt. This is in contrast to the more traditional critical path and PERT methods, which emphasize task order and rigid scheduling. A Critical Chain project network will tend to keep the resources levelly loaded, but will require them to be flexible in their start times and to quickly switch between tasks and task chains to keep the whole project on schedule.

Differences between CCPM and Critical Path Analysis:

The main features that distinguish the critical chain from the critical path are:

  • The use of (often implicit) resource dependencies. Implicit means that they are not included in the project network but have to be identified by looking at the resource requirements.
  • Lack of search for an optimum solution. This means that a "good enough" solution is enough because:
  • As far as is known, there is no analytical method of finding an absolute optimum (i.e. having the overall shortest critical chain). The inherent uncertainty in estimates is much greater than the difference between the optimum and near-optimum ("good enough" solutions). The identification and insertion of buffers:
    • project buffer
    • feeding buffers
    • resource buffers. (Most of the time it is observed that companies are reluctant to give more resources)
    • Monitoring project progress and health by monitoring the consumption rate of the buffers rather than individual task performance to schedule.

How to define the yellow zone from the Critical Chain method for a new project?

I am about to start using Critical Chain for a new project. I've been reading about everything that has to be done and have all required data. Now I want to create my buffer penetration chart but I am not able to find out how to define the Yellow…

critical chain project management

I want to fully learn about critical chain project management in scheduling construction projects. I've gone through many videos and journals, but can't find any clear cut ideas or proof that shows how exactly critical chain method is different from…

How to show critical path INCLUDING completed tasks (in MS Project 2010)

My project is 75% complete and I have no problem getting a nice view in MS Project showing the remaining critical path. However, I want a view that shows how we got to this point, in other words I want to see the full critical path of the project,…
