Apply Six Sigma to Improve the Defect Rate at the Fiber Cable Manufacturing Company

Abstract:

Excellence in production activities is essential for creating high-quality products that fulfill customer requirements, thereby aiding any business in enhancing capacity, brand reputation, and sustainable development. Companies employ Six Sigma as a breakthrough quality improvement method to eliminate defects in operational processes. This study employs the Six Sigma methodology at Company A, a manufacturer of fiber cables in Vietnam, to decrease the defect rate during the surface testing phase of the fiber cable connector for product X. The DMAIC cycle has introduced an improved tool to streamline operations and mitigate the risk of redundancy in sanitation roles, resulting in an estimated monthly savings of 10,451,389 VND for Company A compared to the current situation. The project continues to implement measures aimed at enhancing product quality to meet customer expectations.
