Bright and early the next day, the leadership team assembled in the conference room for Bob’s presentation on Drum Buffer Rope (DBR). When everyone was seated, Bob began, “Unlike yesterday’s presentation on the Theory of Constraints Distribution and Replenishment Model, I want to keep today’s discussion much simpler. In a Theory of Constraints environment, production planning and scheduling is done so with a tool known as the Drum Buffer Rope. Drum Buffer Rope is designed to regulate the flow of work-in-process through a production line based upon the pace of the slowest resource, the constraint operation, also known as the capacity constrained resource.”
