Quality Improvement in Manufacturing Process through SIX SIGMA: A Casw Study of Indian MSME Firm

Abstract

The manufacturing sector is instrumental in driving the economic growth of a country. For realizing the potential of the manufacturing sector in economic development and creating employment opportunities, the Government of India has taken several steps to strengthen the manufacturing capabilities in the country. These initiatives envision India to be a global manufacturing hub. Indian manufacturing had to move several miles for the right positioning of its products in the global supply chains. Besides strengthening the logistics and supply chain infrastructure, there is a need to build on global quality standards and innovation culture. With the support of Government initiatives, several manufacturing organizations are focusing on the quality of their products. This study discusses the implementation of a Six Sigma quality improvement project in an Indian MSME organization involved in the production of portable amplifier systems. The study is conducted with the aim to reduce variation in the final fitting of the manufacturing process. The study also illustrates an application of some quality management techniques, such as Fuzzy-AHP, cause and effect analysis, current reality tree, SIPOC analysis and quality control charts in the DMAIC stages.
