  • Six Sigma has been disseminated into a variety of areas. It is believed that a stepwise understanding of Six Sigma's DMAIC is required for successes of unit projects. Meanwhile, infra-structure factors, such as leadership, organization, personnel management, educational system, etc., are also important to safely implant the Six Sigma into the whole enterprise and to thoroughly create the culture of innovation and enterprise. Careful analysis of those elements makes it possible to draw common connection between Project Management and the Six Sigma. This study drives the success elements for the successful adoption of the Six Sigma in the Korea Western Power Co., Ltd., of which management was evaluated as one of the tops based on the results of 2007 Management Innovation Assessment and arranges the similarity of like this factor and Enterprise Project Management. The results of this study are expected to provide a useful guideline for the adoption of the Six Sigma in whole company level.

  • More than three years have passed since Korean companies introduced Six-Sigma. Each company used a lot of quality improvement tools for years. However, the tools have been taught to the companies with a little understanding of Six sigma tools. Therefore, it is difficult to use the tools correctly at appropriate time. This survey paper was conducted on MBBs and BBs of the manufacturing companies that introduced Six-Sigma. It is intended, in this paper, to provide the companies that will be introduce Six-Sigma a guideline of training course and tools by understanding the importance of each DMAIC stage of Six-Sigma, examining the frequently used tools in each process and their performances, and selecting the key tools for each stage based on the result of this survey.

  • 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.

  • The ultimate objectives of the six sigma activities are to raise quality of products to the level where customers can be satisfied and to improve marketing efficiency through cost reduction. Recently, many businesses have been struggling to find out the most successful way to implement the six sigma to produce better results. This study is significant in a way that it provides readers with an actual evidence of efficiency and effectiveness of six sigma activities in marketing performance for the first time. The major data of this study can be divided into two categories ; First, secondary data research method was utilized to find out the effects of six sigma management on the quality and marketing performances, theoretically and empirically. Second, test of established hypotheses relevant to the effects of six sigma management on the quality and marketing performance based on the propositions drawn from existing literatures, and test hypotheses statistically. This study of six sigma looked into benefits in manufacturing industry in terms of improving quality, cutting cost and decreasing defection product-defect rate. In addition, the study has verified that how the quality performances can affect the marketing performances, such as enhancing corporate image, sales increase and customer satisfaction. The author believes that this study will help many businesses acquire best methods to increase sales and profits. And, business manager will be able to understand where to focus as they proceed with the six sigma project and improve corporate competitiveness.

  • 본 연구는 기업이 경영혁신 방침으로 Six Sigma 추진시 정보보호영역에서의 과제선정에 대한 기준을 제시한다. 기업은 윤리경영을 기초로 사업과 서비스를 통한 수익창출을 목적으로 한다. 기업은 안정적인 사업, 서비스의 정보환경을 확보,유지하기 위해 지속적인 보안활동을 통하여 Risk 를 줄이는 작업을 해오고 있다. 기업의 정보보호 활동과 패턴은 초기의 정보보호 기본기능을 도입, 구축하는 단계에서 탈피하여, 점진적으로 종합적인 관리체계로 수렴되고 있으며 산출되는 관련 정보와 Data 의 정규화를 기초로 정량적으로 관리가 이루어 지는 시점에 와 있다. 그러나, 정보보호 침해사고 예방 및 대응활동, 예측 불허한 상황에서 발생되는 보안사고, 책임문제의 발생, 정성적으로 관리되는 상황 등은 정보보호 영역의 Six Sigma 추진시 과제선정의 어려움으로 작용한다. 정보보호 영역에서 Six Sigma 과제 선정은 일반적인 Six Sigma 과제 선정과는 다르게 정보보호 특성을 고려하여 선정하여 추진하는 것이 바람직하다. 정보보호 활동에 대한 기업의 투자효과도 비재무적 성과외에 경제적 가치요소를 기초로 재무적 성과를 산출하고, 관리하여야 한다. 국내 기업들이 Six Sigma 를 경영혁신 기법으로 확대 적용하고 있는 상황에서 정보보호 영역의 Six Sigma 과제선정에 대한 제안을 통하여 정량적 목표수준 관리에 의한 성공적인 Six Sigma 성과를 달성할 수 있도록 함에 있다.

  • This study is an empirical study on the relationships among success factors of six sigma(support of top management, education and training, performance-based reward, customer and quality focused thought), job satisfaction, and quality performance. In particular, mediating effect of job satisfaction on the relationship between success factors of six sigma and quality performance is empirically analysed to find causes and impacts among these variables. A survey was conducted on the employees working in 'H' company which is applying six sigma at Ulsan City. The survey questionnaires were sent to 300 people and 216 of them were returned. Data obtained was analyzed with SPSS 18.0. The study results are as follows: First, there were positive relationships between critical success factors of six sigma(except support of top management) and job satisfaction. Second, there was also a positive relationship between job satisfaction and quality performance. Third, there were also positive relationships between critical success factors of six sigma(except support of top management) and quality performance. Finally, job satisfaction were full mediating effects on the relationship between critical success factors of six sigma(education and training, performance-based reward) and quality performance. Critical success factors of six sigma(customer and quality focused thought) had a partial mediating effect on quality performance. On the other hand, support of top management had no mediating effect on quality performance.

  • Purpose: In this paper, we investigate whether the endeavors for Six Sigma quality management by a firm have positive effects on its financial performance and the length of Six Sigma implemented period affects its financial status. We find a relationship between Six Sigma implemented period and several financial performance index using a smoothing spline function. Methods: A smoothing spline function is used in order to analyze the relationship between efforts for quality management and financial performance. Specifically, the return on assets, return on equity, sales cost and business fee are investigated as dependent variables and the efforts for quality management as independent variable. Results: As a result of the analysis, the indication is that companies that put effects into the Six Sigma quality management have a positive result in its financial status. In detail, the efforts for Six Sigma quality management have positive effects on total asset turnover ratio and Six Sigma implemented period on net income to net sales ratio. Additionally, companies with longer (shorter) period of Six Sigma program have more (less) improvement in its financial status. Conclusion: It can be concluded that the company's efforts for quality management positively influence financial performance.

  • Six sigma is focused on quality improvement through variation reduction, while lean is on process flow improvement and lead time reduction by waste elimination. However, lean cannot bring a process under statistical control and six sigma alone cannot dramatically improve process speed. Lean six sigma was developed to achieve faster rate of improvement in customer satisfaction, cost, quality, process speed, and invested capital. In this paper we present the importance of using value stream mapping and suggest a guideline on how to integrate lean and six sigma by is proposed.
