The purpose of this research is to describe an implementation of Simplified Drum Buffer Rope (S-DBR), a scheduling methodology under Theory of Constraints, in service operations of a US military base. In doing so, this research contributes in two ways. For practitioners, this research is the first to show how S-DBR methodology can be utilised to improve the performance of labour relations. For academicians, this research is one of only a few to address the how questions of S-DBR use in a service context.
