Drum-Buffer-Rope (DBR) is a key element within the Theory-of-Constraints (TOC). It controls the launch of production orders to the system. Thus, the jobs are launched into the system according to the Bottleneck (Drum) schedule. Although the literature reflects the validity of the method when managing production, most of the works focus on analytical studies, neglecting empirical cases in make-to-order and versatile manufacturing plants. In this research, we present a systematic process to implement the first two steps of DBR. Based on a strategic perspective, we conclude that the resource that controls the launch of orders and the production rhythms must be decision of the Management.
