.6 ¦² Is The Process Of Improvement In The Manufacturing Industry

When General Electric Company CEO Jack Wlech began to praise the new management strategy called Six Sigma. many outstanding enterprises to implement similar plans. However, the result is unsatisfied since these enterprises did not really understand the situation when implementing this management strategy. Although they have spent huge amount of money for planning, little effect can be reached. Moreover,the implementation of this strategy brings pressure to staff members and they feel that the Six Sigma system is too mysterious, too complex and it was trouble imposed by the boss. In fact, only when an organization, from top management to staff, can truly understand and support Six Sigma; Six Sigma will play a significant role.Currently, many enterprises have launched Six Sigma plan. Since 2002, China's aviation industry began to implement this management mode. Despite a great deal of work, and tens of millions of dollars of being invested, the results are not satisfiable.Since December 2005, the author participated in the six-month training of Six Sigma Green Belt After that period, the Six Sigma strategy was applied in engineering practice, and good results have been achieved. In order to better promote the Six Sigma management in the author's Institute, further study is conducted in this thesis project.1. Introduce the Six Sigma background knowledge from the history of quality development, and generalize the Six Sigma methodologies and knowledge management framework in a general system;2. Discuss the theory with a focus on the Six Sigma process improvement methodology and do an in-depth analysis combining cases on how to complete the Six Sigma projects successfully by using the DMAIC;3. A brief discussion of theoretical knowledge of the Six Sigma process improvement methodology ;4. Research on how to successfully implement Six Sigma strategy in Chinese enterprises.By combining theoretical research and engineering practice, this thesis provides a practical approach to efficiently solve problems encountered in real applications.
