Six Sigma: The Breakthrough Management Strategy Revolutionizing the World’s Top Corporations shows how Six Sigma is working at companies such as General Electric, Polaroid, and Allied Signal. The authors helped pioneer Six Sigma while working at Motorola in the 1980s.
At the heart of Six Sigma is the notion that improving quality saves money. The book states that for most companies “the cost of quality is roughly 25 to 40 percent of sales revenue” and “at six sigma the cost of quality declines to less than one percent of sales revenue.”
The book provides insight to what Six Sigma is all about – a change strategy that relentlessly drives defects out of products, processes, and services to increase profitability.
Several case studies are presented that provide valuable insight on implementing Six Sigma. Four case studies are presented. The first case study discusses how GE adopted and embraced the Six Sigma philosophy. Two case studies are presented on how Polaroid utilized Six Sigma to improve sensitometry and strobe exposure variation. The authors return to GE and present a case study on improving a high-speed computed tomography scanner. Finally, AlliedSignal’s journey to Six Sigma is discussed along with the lessons learned during in the implementation process.
