CCM supports the formal reification of the constraints underlying human performance, and the derivation of the implications of these constraints. These two properties make it a powerful approach for describing and reasoning about psychological theory.

"Our goal is to reduce planning time to about 10 minutes for a typical Mars surface mission, and we are a good part of the way there now," he ventured.
