  • 식스 시그마 경영은 제조분야에서 높은 수준의 품질과 정밀성을 달성한 것처럼 서비스 부문에도 적용할 수 있는 강력한 도구이다. 그동안 한국기업의 문제점인 고객 불만족, 고비용 저효율, 진정한 혁신성과를 거두지 못한 구조적인 문제점을 해결할 수 있는 방안이 '식스시그마 경영'이라고 할 수 있다. 식스 시그마 경영은 시행성과를 나타내는 프로세스의 모든 요소를 시그마수준으로 변환하여 현재의 경영상태 분석과 향후 경영관리 지표로 삼을 수 있다. 따라서 본 연구의 목적은 국내 기업에 적용 가능한 식스 시그마 모형을 제시하고 성과에 대한 측정지표를 설정하며, 경로분석적인 접근방법으로 개념간의 유의한 경로를 탐색하는데 있다.

  • It is generally thought that the quality management and the six sigma management innovation are not applicable to service industry, which might be derived from some differences between service and manufacturing industries. However, both are substantially alike in some intrinsic attributes. KT is leading the Quality management and the six sigma innovation activities in service industry, especially among telecommunication companies in Korea. Six sigma management innovation has been fostered in KT within short period of time and played an important role in helping KT privatized successfully. The successful cases of six sigma innovation activities in KT could be introduced to other Korean companies in service industry.

  • HACCP(Hazard Analysis Critical Control Point)은 식품의 원료, 제조가공 및 유통 등 전 과정에서 안전 위해물질이 해당제품에 혼입되거나 오염되는 것을 사전에 예방 감시하기 위한 각 과정을 중점적으로 관리하는 기준으로 1995년 이후 식품위생법 규정에 신설되었다. 국내외에서 앞으로 많은 기업은 이러한 청결기준을 만족시키지 못할 경우 무한 경쟁에서 이기기 힘들다. 이를 해결하기 위한 다양한 방법 가운데 품질혁신 방법으로 많이 알려진 Six Sigma 방법론을 이용하여 프로젝트를 시행함으로써 HACCP을 획득 할 수 있는 방법에 대하여 연구하였다. 본 논문에서는 Six Sigma 로드맵과 HACCP의 프로세스를 결합하여 새로운 로드맵을 제시하였다.

  • There is no doubt Six Sigma is an excellent concept to improve quality of product or service. However, limitations to Six Sigma's implementation process have been discovered that are related to Six Sigma's foundation in statistical methods. The limitations of Six Sigma are overcome by the advantages of a strategic CoP (Community of Practice). Therefore, this research tries to build a strategic CoP for implementing Six Sigma. The method for building a strategic CoP is suggested, and then a case study of a real company is presented.

  • In this study, we took the census of the project satisfaction level of the employees who have participated in Six Sigma projects. We divided and measured the project satisfaction by the steps of performing the project (team building, execution, ownership and support step). We performed the analysis of variance to show the main factors of project satisfaction level, and the tests of homogeneity to know the relationship the business parts and among the job positions each. The results of analysis showed that the satisfactions of the team building and execution step were significant.

  • 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.

  • Survey shows that temperature accounts for 90.6% of dissatisfaction in general hospital environment. In order to improve this situation, operation and thermal data of S hospital collected in 2006 are analyzed. The objective of this study is to find optimum fiducial temperature that minimizes occupants' complaints using 6 sigma method.

  • Many companies desperately effort to find out more effective management method to survive in keen competition. Jack welch of past GE's CEO had said that an excellent result of today's GE management is thanks to Six sigma work. Many korean companies are introduced Six sigma method in their management since late 1993. Six sigma uses a set of strategies, statistics and methods to improve the processes we use to do everything from designing to manufacturing a product from marketing products and services to providing business information to our internal and external customers. The purpose of this study is to overcome these problems and to help make an important decision in establishing introduction strategy by abstracting the reasons and success factors and result indices which are important sources for introducing Six sigma management.

  • After 6 Sigma administration is introduced in domestic in 1997, many corporations are utilizing by survival strategy and method of administration reform. This is applied in all field that this led to R&D from service industry by the next. Success factors by each field was studied and announced applying in various types of business. The Korail and Korea Post, the Ministry of Environment and various public corporation and governmen and municipal office are introduce and utilizing 6 Sigma administration by innovation method present. But, research about success factor that special quality of public sector is considered up to now was almost no. This treatise analyzed 6 Sigma' success factors and effect relation to public corporation.

  • Six sigma has been evolved into three generations. The first generation focused on eliminating or reducing defects as Motorola originally developed and applied. The second generation focused on reducing costs and improving process efficiency as GE extended the first generation. The next generation of six sigma such as D2MAIC(Discovery, Define, Measure, Analyze, Improve, Control) and ICRA(Innovate, Configure, Realize, Attenuate) has been discussed since the beginning of the 21st century. Although the third generation of six sigma emphasizes value creation, but there are few specific tools for its implementation. In this thesis, some tools for finding opportunities for value creation are suggested. It is explained and discussed with examples how the tools can be applied.
