Book Description
The extraordinary breakthrough management program--heralded by GE, Motorola, and AlliedSignal--that is sweeping corporate America with its unprecedented ability to achieve superior financial results.
Six Sigma is the most powerful breakthrough management tool ever devised, promising increased market share, cost reductions, and dramatic improvements in bottom-line profitability for companies of any size. The darling of Wall Street, it has become the mantra of Fortune 500 boardrooms around the world because it works.
What is Six Sigma? It is first and foremost a business process that enables companies to increase profits dramatically by streamlining operations, improving quality, and eliminating defects or mistakes in everything a company does, from filling out purchase orders to manufacturing airplane engines. While traditional quality programs have focused on detecting and correcting defects, Six Sigma encompasses something broader: It provides specific methods to re-create the process itself so that defects are never produced in the first place.
Most companies operate at a three- to four-sigma level, where the cost of defects is roughly 20 to 30 percent of revenues. By approaching Six Sigma--fewer than one defect per 3.4 million opportunities--the cost of quality drops to less than 1 percent of sales.
This is because the highest quality also results in the lowest costs. When GE reduced its costs from 20 percent to less than 10 percent, it saved a billion dollars in just two years--money that goes directly to the bottom line. This is the reason Wall Street and corporations as diverse as Sony, Ford, Nokia, Texas Instruments, Canon, Hitachi, Lockheed Martin, American Express, Toshiba, DuPont, and Polaroid have embarked on corporate-wide Six Sigma programs.
Six Sigma should be of paramount importance to every forward-thinking executive and manager determined to make their company world-class in their industry.

Mikel Harry and Richard Schroeder think they've figured out a management program that really works. While at Motorola in the 1980s, they helped pioneer Six Sigma, a process that "guides companies into making fewer mistakes in everything they do--from filling out a purchase order to manufacturing airplane engines." Since then, the two have left Motorola and have turned Six Sigma into a lucrative business that saw over $100 million in consulting contracts in 1998. And now the book.
In Six Sigma: The Breakthrough Management Strategy Revolutionizing the World's Top Corporations, Harry and Schroeder explain Six Sigma and show how it's working at companies such as General Electric, Polaroid, and Allied Signal. The authors contend that most companies today are working at a "sigma" level of between 3.5 and 4, and that with just a one-sigma shift, companies will experience "a 20 percent margin improvement, a 12 to 18 percent increase in capacity, a 12 percent reduction in the number of employees," as well as "a 10 to 30 percent capital reduction." Sigma is a quality metric that counts the number of defects per million opportunities (DPMO). For example, a sigma level of 3.5 means that a process has 22,700 DPMO; a sigma level of 4.5, 1,350 DPMO; and a perfect six sigma, 3 DPMO.
At the heart of Six Sigma is the notion that quality saves money--lots of money. Harry and Schroeder argue that for most companies "the cost of quality is roughly 25 to 40 percent of sales revenue ... at six sigma the cost of quality declines to less than one percent of sales revenue." The idea is not to create quality-assurance programs but to eliminate the need for them altogether. When a company is operating at six sigma, costs that would otherwise go to inspection, rework, warranties, and customer service drop to the bottom line. Six Sigma is a compelling concept that many companies have tied their futures to. Well written, this book is a great introduction for investors, managers, and anyone who sees Six Sigma on the horizon.

From AudioFile
Six Sigma is a business method for quantifying defects in a product or service transaction based on an ideal rate of 3.4 defects per million opportunities. Corporations achieve better Sigma numbers by scientifically observing business processes, identifying problems along the production path, and institutionalizing reliable solutions. It's a meticulous and comprehensive narrative that embraces concepts from economics, marketing, consumer behavior, and organizational dynamics. It's no wonder these consul-tants are hot and that the book is flying off the shelves. The only problem with the audio version is that their already wordy sentences are read at a relentless pace and with the emotional variability of a chalkboard. Better editing and a different narrator would make these ideas more accessible. T.W.
