This paper is aimed to examine an empirical analysis of the differences among success factors that contribute to high performance of the organizations that adopted Six Sigma according to company size. Furthermore, the research focused on empirically analyzing whether these factors affect marketing performance or not, from the provider's point of view. For this purpose, a survey was conducted among conglomerates, and small and mid-sized companies which are located in the Gumi Industrial Complex that implemented Six Sigma. The following are facts that were found by empirically analyzing the results. Therefore, it is empirically proven that there are quality performance differences according to company size. marketing performance differences from the provider's point of view. the theoretical proposed model, identified the operational definitions and 9 hypotheses were established, there were executed the survey of 250 employees in companies implementing six sigma.

A steel pallet to carry lighter logistic articles is developed based on the DFSS(design for Six Sigma) methodology. Combining the conventional DFSS(Design For Six Sigma) methodology with that of VE(Value Engineering) is the novel feature of this paper to achieve maximum cost reduction. In this paper, systematical steps to achieve the required structural spec's are presented by conventional DMEDI(Define-Measure-Explore-Develop-Implement) process. To imply the target costing, evaluation of functions consisting of the pallet has been performed by value methodology. Then best design concept is selected in the Explore step, following structural optimization utilizing FEM. Finally the performance of prototype is investigated by pilot test in the Implement step. The developed steel pallet is being commercialized in the fields of automated ware house.

Military Barracks and Bachelor Officer's Quarters are public buildings representing architectural characteristics with repeating the same room modules. These buildings require easy dismantling and reusing for the next generation' military re-organization. For these reasons, since 2005, the modular construction has been applied to military buildings. The most important factors required for modular military buildings are standardization, lowcost construction and reusable construction method. However, conventional modular building system have not been matched with these requirements. This study suggests a new modular system for Bachelor Officer's Quarters using Six-sigma design tool. To reflect the voices of customers, market study and surveys were carried out. Through the QFD, the voices of customers were converted into quality characteristics of building system for BOQ. The various design concepts meeting customer's requirement were derived by the QFD and Pugh matrix methodology. The proposed modular building system shows 80% increased factory production rate and 62% decreased weight of steel frame as compared with the conventional modular building system.

GUI는 매우 감성적인 분야로서 객관적인 평가 및 정량화가 어려웠다. 이러한 어려움으로 인해 GUI에 대한 성과 측정이 이루어지지 못함으로써 각 기업에서 GUI및 GUI 개발이 제대로 된 평가를 받지 못하는 상황이 많이 발생하였다. 본 사례에서는 상품과 서비스의 품질 관리를 위한 6시그마 의 통계적 기법을 GUI일관성 평가에 도입하여 GUI의 비일관적인 요소를 불량률로 산출함으로써 GUI의 수준을 측정하고 정량화하는 방안에 대해 모색해 보았다.

Six Sigma is one of the most active subjects in quality management. This study deals with some existing weaknesses that may arise in implementing Six Sigma in real world situations. The main weaknesses discussed here include the lack of understanding of cultural aspects on the nations and industries, the poor linkage between quality, finance and accounting from the bottom line point of view, and the difficult development process of metrics for all improvement results to validate the effect of Six Sigma. Finally, the key success characteristics for a good Six Sigma project are presented.
