Case Study


Statistical process control (SPC) is an excellent quality assurance tool to improve the quality of manufacture and end-customer satisfaction. It uses process monitoring charts to record the key quality characteristics of the component/part in manufacture. This research paper elaborates on one such key quality characteristics of the manufacturing of a spring support in the Tissue Dissector Device. This paper presents a creative solution through case study approach for improving the issue of rejection rate in the spring support in a medical device manufacturing industry by using SPC and define-measure-analyze-improve-control (DMAIC) approach which provide breakthrough quality improvements in short period of time.
