Techopedia Explains Critical Chain Project Management

CCPM addresses issues related to project timing, increased costs, performance and under-delivery, versus traditional methods, such as critical path, where the emphasis is placed on tight scheduling and ordered tasks.

CCPM approaches projects by applying the following steps:

  • Planning: This stage includes defining the critical chain, which is comprised of critical tasks; reducing task estimates and safety.
  • Execution: Project resources are prioritized according to determinations defined in the planning stage.
  • Review: Buffer management is applied to assess the status of each task. Buffers and their consumption rates serve as excellent touch point indicators for projects and related tasks.
