Furthermore, this pa-per puts forward a process optimization scheme for the production changes of G banks ITSM with the Lean Six Sigmamanagement theory. Whats more, the paper dissects the production changes of G banks ITSM by means of DMAICmethod in order to achieve these four goals: Firstly, optimizing the process and improving the internal work efficiencyalso. Secondly, reducing the variation and the error rate and also improving the system availability. Thirdly, strengthenthe business interaction in order that the IT value could be reflected preferably. The last but not least, cutting the over-time is to improve employee satisfaction. But improving the ITSM of the banking industry is our ultimate aim.Keywords: Information Systems; Information Technology Infrastructure Library; Information Technology ServiceManagement; Six Sigma; Critical Success Factors; Commercial Bank1. IntroductionITIL 3.0.This paper is organized in the following: Section 2 is aInformation Technology service management (ITSM)based on Information Technology Infrastructure Library(ITIL), which integrates the best practices of global ITmanagement and forms the normative truth standard toreduce effectively cost and improve the quality of service,is applied widely in the world 1. The whole frameworkof ITIL is illustrated in Figure 1. ITIL, which was de-veloped by the Central Computer and Telecommunica-tions Agency (CCTA, merged with the OGC) of the UKgovernment in the middle of 1980s, is a set of servicemanagement standard library which focuses on IT indus-try. In the past 20 years, the content of ITIL has beenupdated and renewed. Today the OGC has enacted theliterature review, including Six Sigma Process Improve-ment, ITSM and their critical success factors (CSF).

The Improvement of Six Sigma Process The Six Sigma process improvement initiative originatedin 1986 from Motorolas drive toward reducing defectsby minimizing variation in processes, which in turn re-quired explicit measurement of solid metrics 2. Appli-cations of the Six Sigma project execution methodologyhave since expanded to include more explorative objec-tives, such as increasing customer satisfaction, or devel-*This paper is supported by key items of the soft science project in Guangdong provincial department of science and technology (Item Number: 2011A070102001) and the high-tech office in Guangdong provincial department of science and technology (Item Number:2011B010100031), and also the significant science and technology special project in Guangdong provincial department of science and technology (Item Number: 2012A010800032).Copyright 2013 SciRes.TI Y.
