ABSTRACT

The ability to subordinate will define a company’s ability to succeed withthe Theory of Constraints. Exploitation of the constraint is dependenton effective subordination. Without a clear understanding of subordination, the non-drums will create conflict with themselves and others regarding their action-priority decisions and resource allocation. Successful subordination requires all non-constraint resources to understand their relationship to the constraint and to define their actions by the impact the action will have on exploiting the constraint. When applying Drum-Buffer-Rope (DBR), all nondrums must understand their role to support the constraint and the impact of their actions on both the drum and shipping schedules and buffers. Conflict causes disruption. Disruption causes waste and the accumulations of delays. Delays and waste cause costs to go up and throughput to go down. Successful subordination is dependent on the quick resolution of conflict and communication of the resolution to align actions to ensure that the constraining resources are protected from disruption. Minimizing conflict minimizes disruption and waste time, providing more time that can be used to increase throughput.
