Abstract

In the present era of competition, Six Sigma has been considered as a powerful business strategy that employs a well-structured continuous improvement methodology to reduce rejections within the manufacturing processes by the effective application of statistical tools and techniques. This paper presents the implementation of Six-sigma methodology for reducing rejection of automotive part clutch in an automotive industry. The DMAIC methodology has been used to achieve quality level. During this process, data from all possible causes were collected analyses and thereby conclusions were drawn. Implementation of Six Sigma resulted in reduction of rejection of clutch from 15 out of 220 to 2 out of 220 in a single sift and therefore reduced the Defect per Million Output (DPMO) from68181.8 to 9090.9. This increased the Sigma level from 2.99 to 3.86, with an optimalresult. Finally, implementation of Six-Sigma methodology has been results an increase in quality level of the assembly line of that particular clutch in the automotive industry.
