Six Sigma Methodologies: A Review Case Study
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 9
Abstract
Six Sigma process methodologies that focuses on quantitatively measuring a process in order to control and improve upon it and strives for 3.4 defects per million opportunities (DPMO) so that it is within six standard deviations of the mean. However, the term in practice is used to denote more than simply counting defects. Six Sigma can imply a whole culture of strategies, tools, and statistical methodologies to improve the bottom line of companies. In all, six sigma, scrupulous analytical process for anticipating and solving problems. The objective of Six Sigma is to improve profits through variability and defect reduction, yield improvement, improved consumer satisfaction and best-in-class product and process performance. It is a new-fangled way of doing production that would eliminate the existing defects efficiently and would prevent defects from occurring. This paper deals with the implementation of process-level Six Sigma in an automotive component manufacturing plant. The objective for presenting case studies here is to review the importance of Six Sigma strategies in Indian manufacturing companies. The details of Six Sigma methodology and principles are presented here. The case studies mentioned as spot welding, its weld defect due to hold time operation for a product in an automobile component manufacturing company, Anand Motor Products Ltd., an MNC. And accomplished accurate implementation of the proposed corrective plan by using root cause analysis intent the present rejection rate from 3.51% to 1.55%.
