Final answer:
The "drum, buffer, rope" approach is a scheduling method in the Theory of Constraints that involves optimizing production based on the bottlenecks' capacity.
Step-by-step explanation:
In the context of the Theory of Constraints, the "drum, buffer, rope" approach is a scheduling method that helps optimize production. The "drum" refers to the bottleneck, which is the step in the process with the lowest capacity. The "buffer" is a reserved amount of inventory to protect against disruptions at the bottleneck, and the "rope" represents the release of new work orders based on the bottleneck capacity.
