From the reviews: "Six Sigma is essentially a method of assessing and improving quality ... . This text basically describes a large number of reliability measures, and shows how they can be translated into Six Sigma measures. ... the book does a fine job of introducing reliability engineers or reliability theorists into the basics of the Six Sigma methodology." (Moshe Shaked, Zentrablatt MATH, Vol. 1096 (22), 2006) "Six Sigma is essentially a measure of process capability and allows less than 3.4 defects per million opportunities. ... The book is interspersed with several useful case studies from live examples, which make a good reading for a beginner in the subject. The book is recommended to all those who would like to see symbiosis between improved reliability design of a product and Six Sigma strategy for performance improvement." (Krishna B.
