The real estate management includes not only the brokerage, property management, development, investment and consulting which are related to real estate handling, but also the human resources who deal with the real estate business. The level of management quality of Korean real estate business is rather poor. This paper deals with management innovation of real estate management using Six Sigma methodology The main focus of this Paper is to develop strategy Planning, and is to select critical success factors for each strategy to make an advanced management system for real estate business. This paper is a case study, and the target company for this innovation is ERA-Korea Company. Seven strategies are proposed, and for each strategy several critical success factors are suggested. Through this case study, the authors hope that a management quality model for real estate business is proposed, and an improved management method can be adopted in the other real estate companies.

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.

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.

Purpose: In this paper, a Design for Six Sigma(DFSS) methodology based on DMADV(Define-Measure-Analyze-Design-Verify) roadmap is presented. Methods: DFSS tools are given for each DMADV phase which is suitable for the aircraft development process. A cost reduction case study of a navigation simulation is demonstrated. Results: DFSS roadmap are presented with implementation tools for each phase. Conclusion: We propose a DFSS methodology which can benefit the design and development personnel to implement DFSS not only in aircraft industry but also in other order-based industries in general.

The IMD(International Institute for Management Development) report said that national competitiveness of Korea is declined in this year. The main reason for Korea's decline is a largely related to the weakness of corporate competitiveness. The new product development is a necessary ingredient for improving the national competitiveness. The analysis of changing of technologies and customer's needs is needed for successful new product development. In this paper, We found out successful factors of the project by use of DFSS(Design for Six Sigma) and proved them by case study of K-company. Result from this paper is applied to the new product development planning step for K-company and it made a great success rate. It is expected that the result is applied to the same kind industries.

This paper considers a six sigma project for improving the TIP life time in a spot welding process. The project follows a disciplined process of five phases: define, measure, analyze, improve, and control. A process map is used to identify process input and output variables. Nine key process input variables are selected by using C&E matrix and FMEA, and finally four vital few input variables are selected from analyze phase. The optimum process conditions of the vital few input variables are jointly obtained by maximizing TIP life time using DOE and alternative selection method.

다양하고 복잡해지는 소프트웨어 프로젝트를 효율적으로 수행하기 위한 방법론들 중에서 프로세스 평가와 개선에 대한 관심이 높아지고 있다. 그러나 소프트웨어 프로세스 개선을 위한 방법론들은 조직이 비즈니스 목표인 정량적인 품질 관리에 도달하게 하기 위한 측정과 분석활동에 대한 구체적인 가이드라인을 제시하지 않는다. 본 연구는 효과적인 정량적인 프로세스 및 프로젝트 관리를 위해 Six Sigma 방법론을 도입, CMM 레벨 2의 예측공수모델에 적용하여 제시, 프로세스 측정과 분석활동의 개선 가능성에 대해 모색하고자 한다.

소프트웨어 산업 사회에서 프로젝트의 품질과 생산성을 높이는 문제에 대한 여러 가지 방안들을 제시하고 있으며, 컴포넌트 기반 개발 프로세스 역시 생산성 향상에 대한 가능성을 제시하고 있다. 하지만 고객 니즈에 맞는 고품질의 프로젝트를 수행하기 위해서는 체계적인 관리 프로세스가 필요하며 더욱이 컴포넌트 호환 및 상호 운용에 대한 문제점을 해결하기 위한 많은 노력이 필요하다. 본 논문에서는 이러한 문제점들을 해결하기 위한 노력들 중의 하나로 Six Sigma와 OMG의 MDA(Model Driven Architecture) 기술을 이용하여 특정 도메인의 모델 변환(Model Transformation) 구조를 구현하고, 최적화된 Six Sigma관리 프로세스를 적용한 실제 사례를 통하여 프로젝트의 품질과 생산성 망상에 대한 결과를 측정하여 그 효과에 대해서 검증하였다.

This paper considers a six sigma project for improving productivity of the brace complement center pillar. The project follows a disciplined process of fife phases: define, measure, analyze, improve, and control. A process map is used to identify process input and output variables. Eleven key process input variables are selected by using X&Y matrix and FMEA, and finally eight vital few input variables are selected from analyze phase. The optimum process conditions of the vital few input variables are jointly obtained by maximizing productivity of the brace complement center pillar using DOE and alternative selection method.

This research has seven factors such as top management leadership, belt system operation, implementation of systematic methods, adequate project performance measurement, customer focus performance, quality performance and business performance. Those are critical to correct implementation of Six Sigma. I set seven hypotheses which represented the relationships among the seven factors, gathered questionnaires and analyzed the data. Top management leadership affected positively the adequate project performance measurement and the belt system operation, The belt system operation affected the implementation of systematic methods positively and it also affected the adequate project performance measurement. It affected positively the customer focus performance, the quality performance and the business performance, respectively.
