The goal of this study is to stress the importance of 6sigma quality management in improving the inner capabilities of manufacturing and the performances of the company. Six Sigma is widely recognized today as a process improvement methodology that can cut costs and eliminate defects in manufacturing processes. In this exploratory analysis. a model is developed and tested to fit research model with the structural equation modeling analysis. In conclusion. 6sigma leadership and flexible organizational culture are the important drivers among 6sigma activities. IT management strategy is significantly related to 6sigma quality management. 6sigma quality management is significantly related to financial performance. In addition. customer satisfaction is significantly related to financial performance.

6 Sigma uses DMAIC (Define, Measure, Analyze, Improve, Control) methodology as process of solving problem. Enterprise already propelling successfully 6 sigma such as Motorolla, GE and consulting companies leading 6 sigma also propose DMAIC methodology traditionally. But from making 6 sigma activated, enterprises and 6 sigma consulting companies propose 6 sigma methodology matching office indirection part and research and development part. As the forward example, DFSS(Design For Six Sigma) is R&D part application in GE. This study investigates 6 sigma methodology corresponding to Right Process of the kernel factor. Especially for optimum design of the R&D part, revise DFSS definition and general concept organization through Lean DFSS methodology research and analysis.

Recently, as the importance of IT management is increasing, many companies have adopted ITSM(IT Service Management) as a solution to various IT management issues. In addition, some advanced companies are using 6 Sigma technique in their implementation of ITSM. The main purpose of this study is to analyze critical success factors of 6 Sigma in applying to the implementation of ITSM. For a case company, which is known to be successful in applying 6 sigma in its implementation of ITSM, six critical success factors were analyzed. The factors include leadership of CEO, capability and level of 6 Sigma belts, management of accurate data, building organizational systems, training and education, and evaluation and incentive. The results of the study are expected to be used as an useful information for companies to apply 6 Sigma in the implementation of ITSM.

Recently there has been huge efforts to improve performance in construction process by applying emerging techniques such as the Lean principle, Just-in-time concept and so on. However, little achievement as we expected has come out in reality due to the lack of strategy to set a definite goal of the execution and differences of personal viewpoints on construction productivity. Accordingly, it is the most important to promote the circumstances for the construction process improvement by quantifying the goals of respective unit activity groups. This research explores feasible solutions for the improvement of construction projects performance by combining the six-sigma principle for the generic administrative innovation based on the idea of construction process performance. For this purpose, mutual comparisons of various current approaches are performed in an attempt to establish the advantages in applying six-sigma idea and to provide its fundamental strategy. Furthermore, through a case study with the simulation of applying six-sigma to a unit activity group in construction process, this paper verifies that the overall performance improves as the degree of sigma level gets advanced.

Recently. interests in IT Service Management (ITSM) are increasing internationally as well as domestically. In order to realize the benefits from ITSM, it is necessary to institutionalize it as a culture of the organization through effective change management. One of the most promising approach of effective change management is a Six Sigma technique. In this study, we analyze a success case in which 6 Sigma was applied to Service Desk function which is one of the most important functions of ITSM. Through the analyses, this study aims to propose a feasible and specific approach to institutionalize ITSM. To accomplish the objective. the study analyzed specific methods of application of 6 Sigma to ITSM. performance of the project and future directions based on interview and project document/deliverable review. This study could not provide detailed performance measures due to lack of previous research on this topic and difficulty of obtaining quantitative data. However. this study has contributed to proposing a direction to institutionalize ITSM in organizations by analyzing a feasibility of 6 Sigma in implementing ITSM.

Several corporations are adopting the 6 Sigma program. Not all corporations are yielding intended results. The inconsistent results may due to the absence of an adequate strategy formulation of 6 Sigma implementation. The 6 Sigma is a qualify control program but its implications are not confined only to qualify improvement. The 6 Sigma program is a change program to bring about changes in organizations. The thesis focuses on developing an installation strategy or model of 6 Sigma program. The utility of the model developed in this research is supported by the empirical evidence. The validity of the model is tested and verified based on the questionnaire survey conducted at 281 business firms. Few research has adopted the empirical survey. The previous researches are mostly centered around identifying success factors. Unlike the present methodology adopted in this research, the past research methodologies are mainly case studies. The distinctive feature of this research does not confine only to the methodology. This research attempted to identify an installation model that would help enterprises get maximum output from the 6 Sigma program. The suggested model is named as Sequential Model(SM). The SM consists of three stages: the preparation stage, the acceptance stage, and the maturity stage. The model is based on the assumption that organizations should follow three stages sequentially to yield the desired output effectively, The preparation stage is further defined including the organizational change factor, the driving system factor, and the promotion factor. The result variable, the organizational performance, is also further defined including the market competitiveness, the employees competitiveness, and the financial performance. The Structural Equation Model was used to test the validity of the Sequential Model(SM). Several alternatives models were developed and compared. The test results consistently show that the suggested model is a valid one and proves its superiority over alternative models. Through this empirical research, we have shown that the strategies of enterprises in line with the proposed model gained better results over others. The research results would be useful information for enterprises that consider formulation of installation strategy of 6 Sigma program.

This study examined the success factors of six sigma innovation in small- and medium-sized venture companies. The findings are summarized as follows. The importance of 20 items in a total of 4 factors showed that corporate vision was number one in the manager's support, followed by program composition, passionate support, high performance guarantee, and quality activity continuity. This suggests that all members can operate the program by the structured system with a sense of united goal under the company-offered vision as a community when the goal, idea or vision of six sigma activities are shared to members of the entire organization. In addition, high success can be achieved when supported by company-wide enthusiasm and high compensation for sharers' innovative efforts of six sigma at the same time. Small- and medium-sized venture companies should develop brisk six sigma activities of advanced precision parts in such an environment that the technology competition is becoming increasingly fierce. The six sigma movement should be developed as a niche strategy for small organizations with united vision sharing by company-wide operational commitment and high self-esteem for the organizational characteristics of small- and medium-sized venture companies run by key minority organizations and members.
