Implementation of Six Sigma methodologies to gain a competitive advantage: A Case Study approach

Abstract

In the present scenario of the quickly varying financial conditions such as global competitiveness, declining net revenue, demand for first-class variety product from customer end and decreased lead–time, etc. had a major impact on manufacturing industries. Six Sigma is a well-known business strategy for continuous improvement that focuses on enhancing products, processes, and outcomes by minimizing variation in processes and avoiding product deficiencies. Six Sigma DMADV (Define-Measure-Analyze-Design-Verify) methodologies is an influential approach to designing products, processes, and services to fulfill the requirements and potential of the customer while reducing the cost of quality. DMADV uses influential and constructive statistical tools to forecast and enhance quality before prototypes are built.This paper presents the case study approach to implement a Six Sigma DMADV methodology in an auto part manufacturing company to reduce the weight of Variable Transmission Unit (VTU) Housing for H1 transmission and hydraulic common oil vehicle Models to gain a competitive benefit.
