The development process
  Now,people are talking about Six Sigma is already in excess of its original significance statistically. In fact it refers to a set of management methods, not only refers to the process or product performance of a statistical quantity, but also to improve the performance of the company refers to as a perfect target is to achieve sustained leadership and a world-class performance management system, is system problem-solving methods and tools, is based on the data as a decision-making method. 
  The early 80's, Motorola is a global leader in wireless communications products, and with Texas Instruments, as well as compete with Intel's largest semiconductor products vendors’ location. In 1974, the eight largest semiconductor manufacturers have five from the United States, three from Europe. However, the semiconductor market will soon become extremely competitive and only 5 years later in 1979, the eight largest chip makers in every 2 months from Japan. Japanese are also Motorola pager market in the United States leadership poses a threat.
  Motorola CEO Bob Galvin, under the leadership of the beginning of a special working group for Motorola's innovation and business growth plan. In 1981 established a 5 year 10 to improve the quality of speed management strategy. Motorola in its core products in the market share of Japanese competitors have been swallowed circumstances, in order to survive and take the lead in the creation and implementation of 6Sigma. Motorola first to recognize that 'At the same time improve the quality of products can reduce costs by nature', and the development of this concept into the company's management program '5 years of non-performing products to reduce the rate of 10 times, every year 5% -10% of the profits used to improve the quality. ' From 1981 to 1986，220,000 U.S. dollars of investment by the 6.4 million U.S. dollars of savings returns.                          
  GE was first implemented in 1995 is to ensure that 6Sigma continued success! 1995, 6Sigma ideas to improve the model and then General Electric (GE) Chief Executive Mr. Jack • Welch selected and started to implement, 6Sigma company GE has been in great wealth and development. GE Company in 1997 of direct income 6Sigma projects for 320 million U.S. dollars in 1998, 750 million U.S. dollars in 1999 to reach 1.5 billion U.S. dollars, far in excess of the amount of their investment. Welch believes that this is the 'General Electric went through the most challenging and most of the activities of the potential return.'
  Six Sigma success story, in particular, to GE is that it brought about great changes have attracted the attention of Wall Street, which makes the concepts and methods of Six Sigma as the rapid whirlwind around the globe. Hundreds of European, American and Asian multinational companies are actively related to the consulting firm hired to help them design, staff training and counseling projects, with a view to improving customer satisfaction and increase revenue, reduce costs, promote rapid and healthy development, so as to superior returns to shareholders.
  Following Motorola, Texas Instruments, Allied Signal / Honeywell, General Electric, such as after a pioneer in almost all of the Fortune 500 manufacturing enterprises, such as ABB (Asea Brown Boveri), Kodak (Kodak), Siemens (Siemens), Nokia ( Nokia) have started the implementation of Six Sigma management strategy. It is worth noting that the quality of the area has been the world's leading Japanese companies have also joined the late nineties the ranks of the implementation of Six Sigma, including Sony (SONY), Toshiba (Toshiba) and so on. South Korea's Samsung, LG have also begun to enter the Six Sigma journey.
  Phenomenon is particularly noteworthy, since, after General Electric, all companies will be Six Sigma strategy applies to all organizations to optimize business processes, but not limited to the manufacturing process. More and more service businesses, such as Citibank, the largest U.S., the world's largest B-TO-C site Amazon (Amazon.com) and other enterprises have also successfully adopted the Six Sigma strategy to improve service quality, maintain a high degree of customer loyalty, so Six Sigma is no longer a simple business processes for manufacturing of quality management methods, but also the improvement of an effective service level management practices and strategies. In Six Sigma under the influence of the remarkable results, and even some government agencies have begun using Six Sigma methods to improve government services. At present, the average level of U.S. companies from a decade ago about the three Sigma raised to the level of close to five, while Japan has been more than a 5.5 sigma level. It is no exaggeration to say that Sigma has become a measure of the level of a nation's comprehensive strength and competitiveness of the most effective indicators.
  After reform and opening up in China in recent years, set off the introduction of Six Sigma management method to study wave. It is reported that some large enterprises such as Haier, Baosteel, such as the implementation of 6 sigma management to do something to try, but the vast majority of Chinese enterprises, 6 sigma management also just stay in the theory of cognitive level. This phenomenon is mainly due to the scientific management of domestic enterprises foundation is weak, and many work-based management does not do a good job, 6 sigma management is impossible to implement; At the same time, there are also some big companies think they have done in the industry well, 6 sigma management do not seem to have a lot of necessary; more companies that own the production of marketing did not even do a good job, how can they have time and energy to implement 6 sigma, etc., in fact, the more difficult to do business enterprise , the more the need to implement 6 sigma management to resolve the existing problems. And those who think enough has been done good business, in fact, room for improvement still quite large. 6 sigma management in China is still in its infancy, I believe: With the WTO accession, as well as the management level of Chinese enterprises increasing, 6 sigma management in China will be bound to a wide range of applications.
