This chapter has developed the project system requirements and described the critical-chain features and key supporting PMBOK™ system features designed to satisfy those requirements. Key system features are as follows:

• The critical chain identifies the project constraint.

• Exploiting the critical chain utilizes uncertainty management in the form of reduced task-plan durations and a project buffer.

• Exploiting the critical chain requires providing resources the answer to the question, "which task do I work on next?" You can do this with prioritized task lists, filtered resource views, or resource flags.

• You should subordinate feeding chains and resource efficiency to the critical chain with critical-chain feeding buffers.

• Critical-chain projects rely primarily on buffer management for project control.

• Additional features from the PMBOK™ Guide are necessary to complete an effective project-management system.

These high-level system features are necessary and sufficient to satisfy the requirements.
