Exploiting the scarce resource exploits the investment of the whole organization. Theory of Constraints is a five-step focusing process, and the thought process is a framework to check and communicate an individual’s logic on how to apply the five steps. Drum-Buffer-Rope (DBR) was designed inside the five-

step process, and the five steps are integral to managing the system. A chapter on DBR measurement requires an explanation of how to measure and report using the first three steps (identify, exploit, and subordinate). Monitoring the buffers and excess queue at non-drum operations are the basic reporting structures for identifying bottlenecks and focusing subordination efforts. Monitoring the performance of the drums is the basis of exploitation. A company’s ability to exploit the constraint resource is dependent on correct identification of the bottleneck and the ability of the non-drum operations and support functions to subordinate to the care and feeding of the drum.
