In this paper, we analyze and review introduction, implementation, and revision phases in the six sigma movement in LG Electronics. In LG Electronics, 6 sigma activities have been activated not only at manufacturing divisions but also in transactional processes, business, product R&D, marketing, and software development. At present, six sigma is a tool to improve processes and also become the engine of the business innovation. In this paper, concepts and contents of an on-going LG innovation process called TDR(Tear Down & Redesign) are explained in detail. We also propose important aspects and give the future prospect for six sigma.

소프트웨어 프로세스 개선의 효율을 높이기 위해 하나의 개선 모델을 사용하기 보다 둘 이상의 서로 보완 가능한 개선 모델의 통합 모델이 사용될 수 있으며, 그중에 하나가 CMMI(Capability Maturity Model Integralion)와 소프트웨어 식스 시그마의 통합 모델이다. 하지만 소프트웨어 식스 시그마 도구는 그 수가 많고 통계적 지식을 요구하므로 소규모 조직에서 모든 소프트웨어 식스 시그마 도구를 적용하는 것은 어려운 실정이다. 본 논문에서는 조직의 비즈니스 가치를 달성에 도움을 주는 소프트웨어 식스 시그마 도구를 선정하는 프로세스를 제시함으로 소규모 조직에서도 적은 비용과 빠른 성과로 인해 점증적인 소프트웨어 식스 시그마 도구의 도입을 통한 효율적인 CMMI의 구현이 가능케 된다.

Purpose: The purpose of this paper is to study whether the adoption of Six Sigma quality management by a firm positively affects its financial performance. The correlation between the duration of Six Sigma implementation period and the financial status of the firm is investigated as well. Methods: We conduct the analysis using data from Manufacturing Industry Productivity Panel Survey 2013 provided by Korea Productivity Center and Ministry of Trade, Industry and Energy. Propensity score matching is used to reduce sample selection bias of observational study. Furthermore, we use multiple linear regression in order to study the relationship between the implementation of Six Sigma quality management and financial performance. The return on assets and ratio of net income to net sales are considered as dependent variable and implementation of Six Sigma as independent variable. Results: The indication of this analysis is that implementation of Six Sigma quality management does not significantly enhance financial status. The firms that adopted Six Sigma quality management were categorized into three groups according to the implementation period. Comparison of each group with the firms that do not adopt Six Sigma quality management does not show statistically significant enhancement of financial status. Conclusion: In conclusion, both adoption and duration of six sigma quality management do not affect financial performance significantly.

This study has been attempted to find that factors for successful six-sigma implementation influence non-financial performance & financial performance in korean finance industry. In addition, goal of this study is to find out core factor in korean finance industry. To achieve the aim of this study, a document study and interview and an empirical analysis were performed. The collected questionnaires for the empirical analysis were processed statistically through data cording. Cronbach'a was conducted to get the construct reliability. To identify which factors for successful six-sigma implementation influence performances of six-sigma implementation, factor analysis was conducted to get the construct validity. After factor analysis, multiple regressions were utilized to identify the core factors (or factors for successful six-sigma implementation). The result of the study that has been derived through this process is summarized below. Firstly, by analyzing the effect factors for successful six-sigma implementation has on non-financial performance of finance industry, it shows that Process-integration & standardization variable has influenced. Secondly, by analyzing the effect factors for successful six-sigma implementation has on financial performance of finance industry, it shows that 'Process-integration & standardization' variables and 'Customer & Market mind' variables have influenced. The results of this study show that 'Process-integration & standardization' and 'Customer & Market mind' are core factors to influence non-financial performance & financial performance in korean finance industry

The methodology of six sigma originated at Motorola in the early 1980s is now days proved to be an effective way in improving the quality. Many companies are paying their attentions to 6 sigma quality technique, proved to be successful by many examples of advanced firms. However most companies where Six sigma is implemented confront many difficulties in service industry. In paper we research successful Six Sigma in the service industry.

The statistical approach to quality control aims at alerting its user to any variations in the properties of a manufactured product. Motorola developed and pursued a quality management program called six sigma. The goal of six sigma programs is to improve customer satisfaction through reducing and eliminating defects. six sigma uses several statistical measure to characterize defect levels and process capabilities. The upper and lower specification limits are $\pm6\sigma$(sigma) from nominal, and the process mean is centered at nominal. only 0.002PPM are outside specification limits. Cp=2. this is the design target in a six sigma program. This article presents an important tool available for quality control of a production process at the occurrence of defects in manufactured products at view low levels to improve the efficiency of the manufacturing productivity and to satisfy customer through the reduction of defect rates. To understand the consequences of the level of quality on competitive position, a more technical perspective is needed.

This paper proposes a model to assess the maturity level of Six Sigma activities. We classify the maturity level into 5 stages: initial, forming, storming, performing and mature stage. To evaluate the maturity level, 10 categories of Six Sigma with 3 factors each are identified: management leadership, belt system, expert training, establishing execution system, compensation, organization, corporate culture, customer focus, project selection, and management of project results. Scoring 277 items in total, the value of each factor is evaluated by weighted average of those items. Maturity level is appraised by rating the sum of scores of 10 categories that are obtained by summing up the values of its 3 factors. Values of weights and criteria of rating maturity levels are determined by analyzing 90 companies and Six Sigma exper's opinion. This study also shows the actual appraisal results of some companies.

Despite its brilliant success, Six Sigma has suffered from two shortcomings, namely, the lack of a systematic method to identify the right projects in the "Define" stage and to sustain the improvement in the "Control" stage. The integration of Six Sigma and Business Process Management(BPM) seems to be a promising way to overcome the shortcomings of Six Sigma. This paper first reviews the existing efforts on this issue, and then proposes a framework for an effective integration of Six Sigma and BPM. The framework consists of five phases - DEFINE, EXECUTE, MONITOR, ANALYZE, and IMPROVE(DEMAI). A detailed description on the procedural model is also presented.

A new campaign, known as "Six Sigma", to increase market share, decrease costs, and grow profit margins has been adopted by a selected group of leaders in American industry. Although the initial emphasis of Six Sigma was for quality improvement in manufacturing, it is rapidly being applied in key areas beyond manufacturing, and beyond what would traditionally be considered quality. There are a lot of Six Sigma success stories in companies such as Motorola, AlliedSignal, Asea Brown Boveri, and GE. The financial results of Six Sigma in those companies are investigated and their success factors are discussed. The applications of Six Sigma in Korean companies such as Samsung Display Device, Hanjung, and LG Electronics are also introduced.
