Six sigma management has obtained good results in manufacturing and service industry as a new innovation approach to improve the enterprise-wise quality processes. However, there are lacks of implementation cases in the construction industry and furthermore, a results from a few cases applied is not successful enough to draw an attraction against the six sigma method. The main goal of this paper is to provide a comparative study regarding the pre-requisite conditions for the application of six sigma to the construction industry. Then, it present a generic procedure model that can support the introduction of six sigma management. Finally, the model is verified through the case study and lessons learned form a case are presented.

본 논문에서는 한 중소기업을 상대로 진행된 게이트 도장 품질 개선을 위한 6시그마 프로젝트 과정을 소개한다. 프로젝트는 6시그마 개선활동의 로드맵인 DMAIC 절차를 따라 진행하였다. 먼저 Define 단계에서는 고객요구사항 파악을 위해 VOC 기법을 활용하여 CTQ를 선정하였다. Measure 단계에서는 프로세스 맵, 특성요인도, XY 매트릭스, FMEA등을 이용하여 주요 인자들을 규명하였다. Analyze 단계에서는 상관분석, ANOVA, 그래프 분석 등 각종 통계적 기법을 활용해 핵심입력변수인 'Vital Few's'를 규명한 후, Improve 단계에서 DOE를 통한 최적조건을 도출하였다. 또한 Control 단계에서는 최적조건을 유지하기 위한 관리계획 및 실수방지, 표준화 기법을 도입하였다. 이러한 개선 활동을 통해 개선 전 2.957 시그마 수준의 품질을 3.66 시그마 수준까지 높일 수 있었으며, 6천 3백만원의 비용절감을 할 수 있었다. 또한 본 논문에서는 중소기업에서의 프로젝트 진행의 문제점을 제시하였고, 그 해결방안에 대해서도 논하고자 한다.

As the competition between companies are deepened, the number of companies adopting six sigma principles, which is one of the innovative management strategies, are increasing. According to this trend, the changes in both strategies and methodologies of six sigma are continuous. However, the evaluations and the management principles included in the process after the six sigma applications are insufficient, and the cooperation between the parties in the company is also not enough because the application process of six sigma is too complex and not efficient. In order to solve this problem, a research for developing the methodology which can learn about and do six sigma applications is so necessary, specifically for expanding the six sigma applications and introducing the participation of all company members. The purpose of this study, therefore, was to develop and present more efficient Six Sigma applied process by reducing the existing unnecessary steps in improvement one, by applying the examination method of wasteful elements on the potential factors, through analyzing the Six Sigma DMAIC applied case in the construction industry. The result of those application showed that the detection of potential factors using wasting elements was possible in measurement step and that it was possible for the improved process with reduced steps compared to existing process while to remain the outcomes. It is considered that the performance rate of Six Sigma project will be improved significantly because the reduction in the improvement step does not affect the improvement effect within the whole Six Sigma project.

Most companies in Korea that are implementing six sigma programs evaluate belt's project performance based on their own evaluation systems. Financial performance is a major criterion to evaluate project performance. New project evaluation systems which are based on not only financial performance but also non-financial performance need to be presented for better performance system. The study presents the integration system of balanced scorecard and six sigma project evaluation systems to show balanced view points of performance. Each evaluation index of four view points are presented in the study and could be utilized for alternative project evaluation systems.

Due to increase in oil price unstableness and earth warming, energy saving has been one of the most important global issues. We report a 6 sigma project that was carried out to save electrical energy in a university campus. DMAIC, the five-phase process of 6 sigma, was applied for the energy saving campaign. This paper proposes a simple method to quantify the sigma level of the electrical energy saving status and various activities to change the consciousness of all the university members. Results were very satisfied. The 6 sigma project saved about 10% of the total electrical consumption. This is approximately 50 million won a year. The success of the 6 sigma project served as a momentum to promote "Green Scholarship" that has become the center of public interest. Also, we have valuable experiences in the 6 sigma training that shows the university campus can be successfully used as a good place for the actual 6 sigma training.

Recently, ITSM(IT Service Management) is adopted very widely among private and public organizations. The successful implementation of ITSM requires continuous improvement, not just implementation of IT processes and/or ITSM solutions. One of the major tools for the continuous improvement is 6 Sigma technique. This study compares success and failure cases at the project level, and identifies factors affecting successful application of 6 Sigma technique in the improvement of ITSM. To achieve the research objective, this study first identifies and classifies success factors for 6 Sigma application through literature review. Then, factors to be used in the study are determined. Based on the factors, success and failure cases are compared. The research results show that all 5 factors (participation of management, participation of project team, project selection and verification, customer and market orientation, strategy and goal focus) are significantly different between success and failure cases.

The domestic enterprises in order to secure the freshness location of market from the international competition which is keen are propelling a price and a quality high position strategy steadily. It is put in competitive situation with the overseas enterprises and even from construction industry it follows in construction market opening and there is not another idea to the research the management strategies, directions and focus competitive elements of the enterprise against, what it sees consequently and to rise to the priority where the competitive power reinforcement of the enterprise is important, it becomes. Competitive power of like this enterprise for a reinforcement the technique which induces a big interest 6 Sigma is technique from the many companies. 6 sigma preceding researches of manufacturing and service industry the fact that it is accomplished with the object which will carry most. The research which relates with construction industry is staying to an introduction of 6 sigma the investigation phase, the actual introduction introduces and "S" construction there is not only a possibility against the application result of having a limit because it is applying. It is like that but like referring to a minute description for the international competitive power security which it follows in the change which market environment is sudden 6 sigma the introduction will judge, indispensability development of the logical propriety against hereupon and it will reach and it verifies the question investigation for to lead, 6 sigma of the construction companies it confirms the application possibility and presents the propulsion model as 6 sigma the fact that overcoming the limit characteristic of that introduction application as objective of sample research means it will do.

기존에 개별 기업들이 사용중인 고객/서버 모델의 6 시그마 프로젝트 관리 시스템들은 각 기업의 업무와 밀접하게 결합되었기 때문에 다른 기업에는 적용될 수 없는 한계를 갖고 인터넷을 통해 접근할 수 없는 단점이 있다. 본 논문에서는 소프트웨어 개발 능력이 부족한 중소기업에서도 적은 노력으로 6 시그마의 도입을 가능하게 하기 위하여 각 기업의 업무 환경에서 공통적으로 사용되는 기능들을 일반화시킨 웹 기반의 6 시그마 프로젝트 관리 시스템을 개발하였다. 이 시스템은 웹기반으로 설계되었기 때문에 인터넷을 통해 언제 어디서든지 접근 가능하여 시간적 공간적 제약성이 없으므로 기업의 업무 효율성을 제고하였을 뿐만 아니라, 상세한 검색 기능을 제공하여 전사적인 지식 자원들의 공유를 통해 비용 절감 및 프로젝트 수행 기간 단축 등 경제적 효과를 얻을 수 있게 하였다.
