CCM / CPM

Critical Chain Management (CCM)

Where CPM focuses on time, the Critical Chain Method (CCM) shifts the focus to the supply chain. This method is used to map out a critical path based on resource availability. These resources could include people, physical space, equipment, or other physical components. Unlike a CPM map, a critical chain project management map includes scheduled “buffers” to remind a project team that a certain resource is necessary to finish a critical task.

When to use CCM:
CCM is well-suited for projects that rely on limited or time-sensitive resources to complete. Overestimating task durations by building in buffers helps teams meet deadlines even in the face of unforeseen circumstances.

Critical Path Method (CPM)

The Critical Path Method defines the longest sequence of tasks that must be completed to successfully complete a project. These are the tasks that, if stalled, could cause delays in the entire project. The method also maps out the dependencies between tasks and an estimate of how long each task will take to complete.

Mapping out these elements can help establish important project deadlines and define a more accurate project schedule.

When to use CPM:
CPM is best for projects with a well-defined series of tasks that need to be performed in a set order (construction projects, for example). It’s a good option to keep projects with a fixed deadline on schedule.
