Summary

The critical chain for a single project is usually not the constraint for an enterprise performing multiple projects. It is necessary to identify the multiproject constraint and go through the focusing steps to adapt the CCPM process to firms with multiple projects. When you identify the multiproject constraint and use it to schedule projects, it is the drum for your organization. The following list summarizes the key points for CCPM multiproject planning.

• The drum resource is the constraint in a multiple project environment.

• Management must select the drum resource and prioritize all projects for access to it.

• The capacity-constraint buffer ensures that the drum resource is available when needed. The capacity-constraint buffer should be in the range of 25% to 30% of the constraint-resource capacity.

• The drum buffer assures that the drum resource is not starved for input.

• Individual project critical-chain plans operate to the project-chain start times developed from the drum schedule, including the capacity-constraint buffer and drum buffer.

• Management must introduce new projects to the system through the drum schedule by first assigning their priority relative to ongoing projects, then scheduling the drum-using activities.

Practical applications of CCPM have demonstrated the greatest gains in multi-project enterprises. The reason for this is that those environments usually require everyone to multitask much of the time. Elimination of much of the bad multitasking has the greatest impact on overall enterprise project throughput.
