What is Critical Chain Project Management (CCPM)?
Critical chain project management is a method of planning and managing projects that takes into account resource delays. Internal and external personnel (contractors or clients), physical space, logistics, and equipment are all examples of resources.
Critical chain project management examines the timeline and then considers resource availability to see how it will affect project activities and completion. Consider walking down a street. You may be walking at a steady rate, but you will be delayed if your cement supplier is sending cement to finish the road. The task, not the resource, was the cause of the delay.
In the CCPM process, there are nine steps to follow:
- All-time estimates should be lowered in half (the protection that is cut is inserted as a buffer in the project)
- Remove resource retentions from the project plan and level it (in this phase, a critical path is transformed into a critical chain).
- Fill the Project Buffer with a part of the lowered task estimates and place it at the end of the project.
- Feeding Buffers should be placed where the non-critical chain path meets the critical chain path.
- Place Resource Buffers where necessary to protect the Critical Chain from a lack of resources.
- Put Capacity Buffers where they’re needed.
- Tasks should be scheduled as late as feasible (this will help you prevent multitasking)
- Encourage task completion time that is aggressive and emphasize the importance of starting time to finish work as rapidly as feasible.
- Manage buffers and gather information for regulating the plan and, if necessary, executing recovery actions.
