Book DescriptionThe 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.
Amazon.comMikel 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.
--Harry C. Edwards
From AudioFileSix 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.

不错 很划算 书很轻 可以好好看看了
六西格玛创始人写的，很经典。
Clear explanation and good examples.
It's very readable.
作为英文原版书籍，内容比较体系，还有许多值得读者朋友学习的地方
A well-written book that gives insight into what 'Six Sigma' is all about - a change strategy for relentlessly driving defects out of your products, processes and services to increase profitability. It's about leadership and a structured, data-based approach to problem solving. Having been a Wave 1 Black Belt at AlliedSignal during the launch of Six Sigma, I can verify that the Breakthrough methodology (DMAIC)really does work. For those of you who have been through numerous 'TQ initiatives' and countless SPC campaign with no real impact on business performance, the case studies presented in this book are enlightening.
On the negative side, for those who want a complete A to Z textbook on how to implement Six Sigma in their own organization, prepare to be disappointed. No information is provided on the statistical tools that go hand-in-hand with the DMAIC roadmap (I guess the Six Sigma Academy can't give away all their secrets).
In summary, thumbs up if you want an overview and real-life examples of what Six Sigma is all about. Thumbs down in you want a detailed textbook or reference book on the subject.
I had a copy from bookmooch and gave it away. I missed my book so much, I bought another copy. It has the Z table in the back. This helped me to get through some courses on quality statistics and six sigma. The book helped me to understand things like cpk and process capability. I also like some of the last chapters where you find "what makes a bad boss". I actually quoted this to the bosses one day. They were being obnoxious. They realized it was true to. This book helps people on all levels of six sigma find the way to succeed.
If you want to understand what Six Sigma is, what it is good for, and how it can work for your company, then check this out. If you are looking for training materials to become a practitioner, such as learning to be a green belt or black belt, this is the wrong title for you.
I listened to the CD set a couple times, and I still pick up new insights. It starts out slow, but it's worth the listen. I don't know where other reviewers get the idea this is a commercial - I didn't get this impression at all from the audio version.
What was good
From my prespective, readers who purchase a book on Six Sigma are somehow experienced on Quality processes and want to learn more on the topic. However, this book is a total dissapointemet, as it is more of advertisement than knowlege. The author could have written ten pages to describe what was said on 281 pages! All that was written were Black Belts, how vital were they to the process. No emphasis on the Six Segma process, no description of the mechanism from an engineering prespective. It is more of 'Six Segma is the best and we can deliver the impossible' approach! For me this could be a good Novel to read, not for serious Managers.
