Project Management
& Engineering

CCPM is the combination of Critical Chain schedule development and control with the Project Management Institute (PMI) Project Management Body of Knowledge(PMBOK). It was first described completely in Larry Leach's book:

Leach, Lawrence P. (2000) Critical Chain Project Management.
Boston: Artech House.

CCPM shares the Critical Chain understanding of the reality of variation in task duration and dependence of tasks in a project network. CCPM is a probabilistic method, although the Gantt charts drawn for CCPM plans may look the same as deterministic Critical Path schedules. CCPM eliminates start and stop dates for each task, and consolidates the provision for task duration variation into buffers.
