Six sigma has been the most influential management innovation program since 1996 in Korea. As a result of successful implementation of 6 sigma, there have been a number of dramatic quality improvement cases. However, no empirical study of 6 sigma implementation study has done especially in the service industry of Korea. This article reviews status of finance companies which implemented 6 sigma programs in Korea and then demonstrates the relationship between 6 sigma problem solving tools such as analysis of variance and graph techniques, etc and project success and operational performance. Customer survey tools, process analysis, and documentation tool are identified as influential tools on project success. Tools of measure steps, customer survey tools, and documentation tool are found as influential tools on operational performance.

This paper purports to investigate the statistical basic principles through "TRIZ-used 6-sigma integrated activity design" and further, to raise "the importance of measuring technical innovative activities based on 6-sigma integrated design methodology by organization". This paper intends to investigate how the activities of the best conditions, which are necessary for the stage of 6-sigma design, are chosen in the TPM-based 6-sigma integration activities. And it will examine the options, when used together with other technique, in the probability statistical methodology. Through the combination of the situations which are chosen when activity techniques, which are mostly used for production and technology, and 6-sigma integration activities are used together, it intends to practically use as the basic data for company standards.

In 1999, Six Sigma was introduced into Korea and after that it had general influence on company-wide management system. Quality Circles apply the various quality problem solving techniques such as QC 7 Tool, New QC 7 Tool, and statistical methods to rationalization, improvement in the shop floor. This paper empirically investigates the effects of Six Sigma on Quality Circles by analyzing the difference of problem solving technique's use. The number of teams employed in this study is 342, which participate in National Quality Circles Contest from 1997 to 2002 in Korea.

It is important to estimate the magnitude of settlement and the time of primary consolidation in geotechnical engineering projects. For these purposes, site explorations and laboratory tests are usually performed. However, the mechanical properties determined from laboratory tests on the samples obtained by different sampling techniques show different trends. In this study, three types of consolidation test were carried out on the soil samples obtained by three different sampling techniques (76mm tube, 76mm piston, and block samples), to verify the effect of sample disturbance on consolidation properties. It was found that sampling methods have influence on the $\varepsilon$ - log $\sigma$'$_{v}$ relationship. While insignificant difference of compression indices from the samples obtained by different sampling techniques was observed in compression region, these values showed a different trend in precompression region. The values of $c_{v}$ and k of block samples had a tendency to be larger than those of piston and tube samples. At consolidation pressure larger than $\sigma$'$_{p}$, however, these properties became similar regardless of sampling methods. The block and piston samples gave slightly higher values of $C_{a/}$ $C_{c}$ than tube samples. In the results of I $L_{EOP}$ and CRS test, it was observed that the values of $\sigma$'$_{p measured}$/$\sigma$'$_{p best estimated}$ of Yang-San clay decreases when strain becomes larger than 1.0% and that precompression strain of block samples is in the range of 1.5~2.0% while those of piston and tube samples are 1.75~3.75%. It was also shown that the values of $\sigma$'$_{p}$ of block samples exceed those of piston and tube samples by about 6~10%.6~10%.%.%.%.%.

This study aims to analyze chemotherapy medication safety management system and formulate efficient methods to solve problems in the medication safety practices through application of 6 sigma techniques. From the results of analysis conducted, targeting nurses, such 3 factors as process-related factor, nurse-related factor and environment-related factor were identified as problems of the chemotherapy medication safety management. Through analyzing the prior knowledge about chemotherapy mediation safety and level of performance of nurses, the educational performance to complement deficiencies were selected as the final improvement plan, and the improvement activities were completed through drawing out management plans that specify management methods and countermeasures in the event of problems.

The service industry is becoming greater importance in the current economy. The service quality has become an important competitive factor in service industry. Until now, 6 sigma method has well accomplished in manufacturing industry. 6 sigma method has been applied to the service industry to improve service quality, but it has not been reported that 6 sigma method is a successful method for service industry to improve service quality. In this paper, we suggest a MAVIC model to improve service quality. It is a model which is combined with advantages of a SERVQUAL model and 6 sigma method. We has proved its effect with applying a MAVIC model to real service techniques.

Enterprises are continuously trying management innovation activities for survival. Among representative management innovation activities in domestic manufacture enterprise, which are TPS, 6 sigma, Lean 6 sigma etc. Many enterprises through these reform activity have gotten good result. However, these techniques have merits and demerits according to circumstance of enterprise. Specially, there are a lot of difficulties in medium and small size enterprises. In this research, We introduce Lean-SMAIS Method for medium and small size enterprises that is consists of the merit of lean 6 sigma and software(which is called ProEye). We prove Lean-SMAIS method is useful by applying medium and small size enterprise A company.

In order to improve the performance of succeeding superstore construction projects, it is essential to find out an effective way for applying the opportunities of improvement on their repetitive construction process based upon the analysis of various success or failure cases occurred on previous similar projects. This research study suggests a way to improve their construction process through the applications of six sigma techniques on superstore construction projects. A literature review was implemented on the basic concept of six sigma and its general performance steps, and the step by step applications of six sigma techniques were accomplished regarding to the speciality of superstore construction projects. The opportunities of improvement for superstore projects were figured out, and the result of their applications on other superstore projects was analyzed. As a result, it was found that the adoption rate of identical success or failure cases was increased. Also, there were several improvement effects on the projects such as $10{\sim}20$ days of time savings by projects, decrease of reworks by preventing failure cases, quality and safety improvement. These results indicate that the six sigma techniques are applicable and valuable for improving the repetitive process of superstore construction projects.

Successful Six Sigma methodology involves continual success of projects, each incrementally moving the organization closer to its strategic goals of shareholder return and customer satisfaction. However, Six Sigma methodology has some disadvantages in long-term technical strategy parts, systematic technology management techniques and concrete idea creativity methodology. To complement these Six Sigma problems, Triz technique is considered. Triz focuses on solving such problems efficiently, effectively, and creatively. The purpose of this paper is to improve the temperature inspection method of a refrigerator through the DAGEV(Define-Analyze- Generate-Evaluate-Verify) cycle of Triz.
