Six Sigma approach is generally employed to improve the sigma level of manufacturing or service
processes by reducing their deviations and defects. Six Sigma provides the opportunity to
eliminate mistakes improve morale and save money. Doing things right in first time and keeping
them consistent is the only idea behind Six Sigma. Its fundamental objective is to achieve
customer satisfaction with continuous improvement in quality and productivity. Mostly we are
emphasizing on various tools or techniques being used during DMAIC projects and almost ignore
the procedure to execute different phases of the Six Sigma project. This book provides unique
step by step methodologies to perform Define Measure Analyse Improve and Control phases of a
Six Sigma project respectively. An empirical investigation has been carried out in a
make-to-order type (medium sized) foundry and Six Sigma is successfully implemented by
decreasing the scrap of piston castings appreciably. The book focuses on scrap reduction
specifically in Indian foundries and tries to find out the reasons of low productivity index.
It also tends to shatter the various phobias of SMEs in context of Six Sigma by validating the
compatibility of proposed methodologies through a successful case study in Indian foundry
environments.
