The purpose of this study was to clarify whether QC activities performed by employees responsible for the central supply room in small groups to identify problems and voluntarily help with improvements could actually improve the performance and reduce costs. Regarding the methods, problems extracted from free discussions were reorganized according to the 4 Ms (men, machines, materials, and methods) of the QC technique, and regarded as "causes" in the central supply room. Then, a "characteristic" was derived from these causes to create a characteristic diagram. Finally, goals per cause were established based on the characteristic, measures to achieve the goals were planned and implemented, and the results were evaluated for the effects of QC activities in terms of improving performance and cost reduction. The study identified four causes, including "equipment / allocation," "supply systems," "sterilization technologies," and "human resource management," and a characteristic : "What are performance problems in the central supply room?" This demonstrated that setting goals per cause based on the characteristic and taking measures to achieve the goals had resulted in improvements in performance and cost reduction. QC activities were found to be effective in appropriately modifying the working environment, realizing performance improvements and cost reduction, and enhancing employees' motivation.
