  • Many companies in Korea have introduced and put Six Sigma to the practical use recently, others are under consideration to introduce it. As we consider how to recognize and to apply it, we are able to know there is a difference among companies and it differently influence on those companies. In this paper, we analyze the structural differences between Quality Management and Six Sigma movements through the questiionnaire designed effectively to investigate them. We also examine the controversial points, suitability as the management model, the level of Quality Management and Six Sigma movements, and analyze how much the movements effect on the management activities. Finally, we show how to improve the Quality Management and Six Sigma movements in Korean companies.

  • Global regulatory pressures relating climate change and environmental responsibility are asking companies to find out the best way for sustaining their continuous business growths. It could be known that inadequate management for environmental issues are bad for business, negatively affecting brand image, causing unnecessary losses and costs for environmental preservation. For this reason, environmentally conscious green business growth has been recognized as an essential requirement for a company to stay in business. Many companies are looking for green business opportunities of improving their environmental and financial results, and struggling with how green fits into their business. In this paper, the Green Six Sigma, an environmentally conscious Six Sigma methodology, is presented as a way to find solutions for green growths. The Six Sigma is known as a disciplined, data-driven approach and methodology for achieving world-class performance in any process from manufacturing to transactional. In chronological order, the Six Sigma has been evolved from Motorola's quality-oriented methodology to GE's cost-oriented lean approach, and is being evolved and developed as an environment-oriented green growth approach. There is no doubt that the Green Six Sigma, as an engine of green growth, is a power tool for achieving competitive business performance and reducing the impact on the environment.

A Study of the Effects of Champion's Transformational leadership on Belts' Creativity: Based on Mediate Effects of Belts' Intrinsic Motivation and Project's Learning and Growth (6시그마 챔피언의 변혁적 리더십이 창의성에 미치는 영향에 관한 연구 : 내재적 동기와 프로젝트 학습과 성장성과의 매개효과를 중심으로)

  • The study attempts to propose and test a causal research model using SEM (Structural Equation Model) to determine whether there is a relationship between six sigma champion's transformational leadership and belts' creativity based on the mediated effects of intrinsic motivation and project's learning and growth. The subjects of the study composed of 134 belts from manufacturing and service firms implemented six sigma. Empirical results show that transformational leadership is positively related to intrinsic motivation and project learning and growth. In addition, intrinsic motivation and project learning and growth are positively related to creativity. The results of the study imply that creativity of six sigma belts would be enhanced by implementation of six sigma projects and utilizing six sigma tools and methods.

  • Evaluation indices for products or services are important to improve the internal process of the company and to compare those with competitive ones. The sigma level in Six Sigma management does important role to evaluate the core characteristic, CTQ(Critical To Quality), derived in the considered product/service or process. In this research, we propose an overall evaluation index for the product/service or process with multiple characteristics, in other words, multiple CTQs. The proposed overall evaluation index is useful for the cases that the single CTQ is not enough to evaluate the practical interests, for example, the final products and services with complex procedures and relatively large scaled processes. This approach is discussed with sigma level for applying Six Sigma Projects, however, it is applicable to indices based on proportion or percentage as well. The practical examples with a manufacturing process and a customer survey based on focus group interview are given for illustrations.

  • Nowadays, globally high-grade companies have done their best for increasing their competitive power through a many kinds of method in incisive competition for making certain of a pacesetting position. Among the rest, Six Sigma have been the best methodology of improving process and have proven to be effective by the result of improving process in many of manufacturing business, however, it has not obtained excellent results in the transaction business. In transaction business, a $30\sim50%$ costs in total costs is generated by slow-speed working and reworking. The slow processes decrease the quality and increase the cost, which decreases customer satisfaction, and finally the income is decreased. All of them are so called wastes in processes. For this, adopting of lean six sigma methodology in process management can eliminate the wastes and reduce the variation. This study focuses on distribution with the domains like capacity, layout, amount of location, assignment of product, operation procedure and operation rule in order to improve these domains, we make a further application of eight analysis ways based on DMAIC method for improving operation of processes of distribution center as the third profit source. The goal of this study is to trace an approach that can easily adopt of Lean Six Sigma in operational management of distribution center by a kind of data, analysis method and template.

  • The object of this study is to present performance by applying six sigma quality management to a construction company. The research method involves to investigate and analyze data regarding six sigma projects in S construction company and a questionnaire survey from the personnel of the S construction company. The results of this study are as follows 1) S construction company utilized the six sigma quality management for 258 projects during the years of 2003 and 2004 and this bring the effect of cost reduction for quality. Moreover, before using the six sigma quality management, the average level of sigma in this company was around 2.8, after using this, the level increased to 3.6. Particularly, the construction management part, the level increased from 1.3 to 2.6.2) respondents recognize that quality management costs by applying six sigma is reduced. but there is only a little operational efficiency because it is In the early stage of applying six sigma quality management.

  • Ten years have passed since Samsung SDI and LG Electronics introduced six sigma. Six sigma spreads on the wide industry areas such as service and public sectors as well as manufacturing industry. Six sigma speaks for Korean enterprise's management innovation now. Then, can we evaluate that Korean enterprise's six sigma has settled down successfully? This study compares Korean enterprise's six sigma with those of Japanese and American enterprises in the view of leadership, project, people, and methodology. We suggest five topics for the successful settlement of six sigma in Korean enterprises; 1) Role of executives and managers should be changed more actively, 2) Strategy-connected projects should be excavated, 3) Utilization and development plan should be made for black belt and master black belt, 4) Six sigma methodology should be advanced, especially DFSS methodology, and finally 5) Several innovation methodology should be integrated.

  • Since the six sigma strategy was first introduced to Korean enterprises in 1997, it has been taken as an important business strategy to strengthen the competitiveness of major Korean companies under the global competitive environment. These major companies also demand their suppliers to implement six sigma. But small and medium sized companies have several barriers to overcome for successful implementation of six sigma. First, the financial status is not so sound to support initial expenses for launching six sigma. Second, physical and human resources are not sufficient for driving six sigma. And finally, the infrastructure is not well established to manage and support the six sigma program. In this paper, we suggest a method to overcome these barriers and propose a model for establishing six sigma in a small and medium sized company. We also provide some practical case studies.
