산업사회와 소비자는 갈수록 소량 다품종과 빠른 Delivery를 요구하고 있다. 생산라인은 급격히 자동화되어 가면서 기존의 단순한 Cost 구조에서 복잡한 Cost 구조로 심화될 뿐만 아니라 제조간접비용의 중요성도 점차 이슈화 되어 가고 있으며 시장에서의 경쟁은 갈수록 치열해 짐에 따라 판매비, 광고비 등의 부담도 점차 증가되고 있다고 하겠다. 이러한 시점에 세계 유수한 기업들은 Six Sigma 품질 혁신 활동을 통해 그들에 절대적인 부담이 되고 있는 비용의 절감뿐 아니라 품질 향상을 통한 고객 만족을 이끌어 내고 있다. 본 연구는 Six Sigma 품질 혁신 활동과 제약경영이론(Theory of Constraint)의 조합을 통한 시너지 효과로 생산 라인의 생산성 향상을 성공적으로 이끌어 낸 사례를 제시하고 있다. 즉, 본 연구의 목적은 Six Sigma 경영 혁신활동과 TOC 이론의 조합을 통해 생산 라인의 생산성 향상을 극대화 하고자 하는데 있다고 하겠다. 이를 위해 개선 활동의 프로세스 진행은 Six Sigma 활동의 DMAIC 프로세스를 따랐으며 세부 단계에서의 개선 아이디어를 발굴하기 위하여 Thinking Process를 적용하였다.

For the success of total six sigma innovation, it is necessary to involve the suppliers In the six sigma activities. This paper presents the deployment and support system of six sigma innovation for suppliers, with the application to an aerospace production company. The process of project selection, project implementation, financial effect verification, benefit sharing is presented. This paper will benefit the companies which are going to enhance all the companies in the supply chain via six sigma activities.

This study deals with the improvement of production process on a flow production system with the consideration of six sigma. We analyze the production process and survey the important factors of improvement of productivity. Using a six sigma, we find strategic point and suggest a reformation of production process. We applied a simulation technique to simulate the production line proposed by the result of the Six sigma. With the result of the simulation, this study analyzes the propriety of production line and proposes the alternatives of new production process.

The case company has driven the six sigma innovation programme company wide for the last seven years without any stop in spite of the CEO change. There was neither any benchmark nor the sufficient number of internal experts during the initial stage of driving six sigma. However, the company raised a lot of innovation experts such as MBB, BB and GB, thereby successfully changed the way of employees' doing work and reaped an enormous amount of either visible or invisible performances as a result of implementing the six sigma innovation programme. This paper deals with both main activities undertaken at each stage of the innovation life cycle of six sigma and their performances in a ICT (Information Communication Technology) industry. The performances are described from the four aspects of a balanced score card (BSC) and finally some strategic implications suggested.

The 21st century is often called the knowledge-based information society. A new term, Data Technology (DT), which handles data and creation of information, is defined. A few important concepts of DT which are related to Six Sigma are described. Also some characteristics of Knowledge Management (KM) which provide new knowledge are explained. As a new direction of Six Sigma, Six Sigma Focused on Knowledge Creation (SSFKC) is suggested. The way of implementation of SSFKC and its relationship with DT and KM are elaborated.

Prior to Six Sigma, many companies had adopted a policy management method designed to manage business performances through the top-down deployment of management policies. This policy management method and the Six Sigma CTQ Flow Down will make a good combination when their merits are developed and systemized as the management innovation program which enables to set up innovation targets along with management targets in the stage of strategic planning and to participate all the personnel from top management down in achieving th targets. This paper will help the companies implementing Six Sigma improve their management constitutions and achieve better management performances through the integration of policy management and Six Sigma.

Six sigma methode was applied for optimization of flow field design of a proton exchange membrane fuel cell (PEMFC). The optimization between number of channel and channel/rib width was suggested in this paper with six sigma method. With the help of six sigma design of experiment (DOE) the number of experiments may be reduced dramatically. The fuel cell channel design optimization with results of these experiments with a 100 $cm^2$ serpentine flow field indicates a optimization data for a given constant operating conditions.

Six Sigma is widely recognized as a process improvement methodology. In these days, many organizations today are considering how to choose six sigma project. This study is to provide six sigma project selection criteria by comparing public corporate with private corporate using AHP. In this exploratory study, criteria to select six sigma project is developed and suggested to fit goal of each organizations.

This Purpose of this paper is to suggest the effects of success factors of six sigma on the management performance. This dissertation deal with key factors that led to successful implementation through existing literature. Therefore, this major success factors of six sigma revealed performance of cost reduction and improving quality. This study is empirical analysis the effects of six sigma performance of cost reduction and improving quality)on the management performance(profitability, growth, market value). The results of this study, six sigma quality performance turns out to have positive(+) effect on the all management performance.
