  • Purpose: Many firms have implemented Six Sigma in order to improve employee's creativity and performance. However, few researchers have studied the effect of Six Sigma on performance through creativity process. This study aims to investigate the impact of Six Sigma, exploitation, and exploration on performance. Methods: Based on literature review, this paper develops hypotheses and tests them by employing a structural equations model. Using survey data of 209 Six Sigma experts who have conducted Six Sigma projects from different companies, this study empirically shows that the activities for Six Sigma enhance exploitation, exploration, and performance. Results: Six Sigma affects exploration and exploitation, each of which in turn enhances performance. It is noted that Six Sigma has an indirect influence on performance through exploitation and exploration. Conclusion: Apart from Parast(2011) who insists that Six Sigma is effective in improving exploitation rather than exploration, this study suggest that Six Sigma can affect both in order to enhance corporate performance.

  • Since the advent of Six Sigma in 1980's, Six Sigma is widely used in various industry areas, such as manufacturing, financial, government, and service, and proves its innovation ability and value by providing lots of success stories. Several researches have been conducted to adopt Six Sigma for Software Development and Software Quality Assurance-Software Six Sigma. Although the wide use of Six Sigma, there is no software tool to support the execution of Six Sigma Project. For this reason, the Quantitative Six Sigma Project Management is required to support for measuring and analyzing Six Sigma Projects, storing and reporting the results from Six Sigma Projects, and managing Six Sigma Projects through the whole process of, DMAIC or DMADV. In this paper, we introduce the design and implementation of a Quantitative Six Sigma Project Management Framework and Tool. The execution of Six Sigma Project based on Six Sigma Project Management Tool benefits the quantification, the systematization, and the integration.

  • Purpose: Most enterprises adopt six sigma acts to maximize the business performance with raising the executiveness for the project improvements in each parts. But there are little studies about six sigma actual operations in manufacturing whether the six sigma improvements that have injected a lot of budget, efforts, labours and time are run properly. Methods: This study select 31 interviewees who have MBB or BB from 5 large enterprises running six sigma over 10 years and 5 SMEs running six sigma over 5 years to understand and review the operational status of six sigma actions in manufacturing industry and to secure representativeness. This study identify the operational status of six sigma actions and key factors enhancing or impeding execution of six sigma projects through face-to-face interviews and online surveys by e-mail. Results: This study figured out the operational status of six sigma actions and key factors enhancing or impeding execution of six sigma projects. We used SPSS 16.0 for the reliability and the validity of survey data. Conclusion: There can be a lot of different factors that affect six sigma project improvements besides the key factors from this study. More study need to think of the organization characteristics and the basic conditions and to remedy the unreasonable points and defects rather than following foreign companies and enterprises.

  • It is generally thought that the quality management and the six-sigma management innovation are not applicable to service industry, which might be derived from some differences between service and manufacturing industries. However, both are substantially alike in some intrinsic attributes. KT is leading the quality management and the six-sigma innovation activities in service industry, especially among telecommunication companies in Korea. Six sigma management innovation has been fostered in KT within short period of time and played an important role in helping KT privatized successfully. The successful cases of six sigma innovation activities in KT could be introduced to other Korean companies in service industry. Five key factors for the success of six-sigma innovation activities are suggested, The hidden factory in all the fields of company should be eliminated. Six-sigma projects need to be connected with the company strategy. The project should be carried out intensively in a short time. The innovation activities in the field need to be integrated. The best practice of six-sigma should be disseminated in the field.

  • 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.

  • To maximize the operational efficiency of production and operations systems, Six Sigma and Lean Production System have been widely used. The main focus of Six Sigma is reducing variations, whereas that of Lean Production System is eliminating losses. To take advantage of the two approaches Six Sigma and Lean Production System was integrated into Lean Six Sigma, and the integrated approach has been used in recent years. In the implementation of Lean Six Sigma, the problems under consideration have often physical or technical contradictions which are difficult to be solved by conventional methods. To solve such contradictions TRIZ is useful in many cases. In this thesis, it is considered that how TRIZ can be applied to Lean Six Sigma. An integrated road-map of Lean Six Sigma and TRIZ is suggested and some cases are reviewed.
