Critical Chain Project Management (CCPM)

bullet1 Identify
bullet2 Multi-Project

bullet3 Drum

When operating in the Critical Chain Project Management (CCPM) mode, the drum resource is the constraint of  a multi-project system. It is the most loaded resource shared across projects. It need not be the critical chain, although it frequently is. It should be a resource that is difficult (cost, time, unique) to elevate (increase). The drum resource is only meaningful in a multi-project environment.

bullet4 Project Priority

Project priority is assigned for access to the organization constraining resource, called the drum. Priority assignment leads to staggering the start of projects to not overload the drum resource. Priority assignment should be based on maximizing the business goal, now and in the future.

bullet4 Schedule

The Drum Schedule schedules use of the drum resource for all projects. It requires the drum resource demand from all projects. It identifies the links to projects through the Capacity Constraint Buffers.
