The Relationships among the Degree of Quality Cost Deviation, Quality Management Activities and Performance
Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 1~18
Quality is a critical competitive factor in today's environment because of the impact of quality on costs and delivery. Many companies regard quality as a key concept of company strategy in order to achieve the competitive edge. Measuring and reporting quality cost is the first step in quality management program. The supposition of quality cost model is that investment in prevention activities will bring rewards from reduced failure costs, and that further investment in prevention activities will show profits from reduced appraisal costs. In this study, the degree of quality cost deviation is conceptualized. This means a deviation between the ideal and present ranking in the amounts of quality cost categories. This study analysed that the effect of its deviation on quality management activity and performance variables. However, there are no difference in these variables. The major reason is that most of companies are endeavoring for quality management but operating quality cost system unsystematically. The review against a prevention and appraisal activity is necessary.
The Relationship between Empowerment and Service Quality, and Moderating Effects of Tenure
Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 19~35
With the increase in family income in Korea and the improving quality of life, there is a rapid growth in the restaurant industry. Therefore there is a demand for quality service in this industry. This paper reviews the relationship between service quality and the degree of employee empowerment. The first objective of this research is to test the effects of employee empowerment on service quality, and the second one is to test how tenure affects this relationship. According to statistical analysis, meaning, competency, and autonomy generally have an affirmative impact on many service quality factors. Also the results of regression analysis to test the moderation effect show that long term employees are more sensitive to autonomy than short term employees.
A Comparative Study of Measuring Air Liners′ Service Quality
Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 36~54
There have been academic debates upon which measure is more desirable in measuring service qualify between SERVQUAL and SERVPERF. In addition, Korean air lines industry is rapidly growing due to the increase of Koren family income and globalization. This study tried to contribute to both academic and practical issues. This study compared SERVQUAL and SERVPERF measures to determine which is superior to measure service quality in Korean air lines industry. Data was collected from two airliners' customers of Korea. According to the results of confirmatory factor analyses, regression analyses and analyses of goodness of fit, SERVPERF appears to be better in measuring service quality in Korean air lines industry than SERVQUAL. We suggest that SERVPERF be used to measure service quality in Korean air lines industry.
A Comparative Study on Total Quality Management Education between Manufacturing and Service Companies in Korea
Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 55~63
Total quality management (TQM) is regarded as a tool for improving the competitiveness not only for a manufacturing sector, but also for a service sector, The objective of this paper is to classify TQM education by management level, to identify how TQM education be implemented by the type of industry, to analyze the relationship of TQM education with business performance, and finally to analyze the difference between companies with ISO certification and those without ISO certification in terms of TQM education. The findings suggest that there was a significant difference between manufacturing and service sector in TQM education level. Also, the relationship of TQM education with business performance was partially correlated. Finally there was no significant difference between companies with ISO certification and those without ISO certification in terms of TQM education.
A Study on the Effects of Rewards Factors on Performance of Total Quality Management
Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 64~80
According to the study of TQM implementations, the odds that an organization will successfully implement total quality management are two to oneagainst it. However, organizations armed with knowledge of the factors that have the biggest impact on their success can take steps to influence or change those factors. In this paper, we first are reviewed those rewards factors through literature study and gave the test for them in the Korean industry. This study also proposes that appropriate successful rewards factors are necessary for TQM implementations.
An empirical study on the major factors of implementing six sigma successfully through black belts
Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 81~94
Six sigma is a management innovation strategy which improves all managerial processes in an integrated manner, Six sigma can be applied to every aspect of managerial functions such as marketing, engineering, purchasing, accounting, and so on. Six sigma is trying to solve quality problems from the customer's viewpoint in the scientific manner, thus maximizing profits through the elimination of quality costs. This paper is presented to verify empirically the successful factors of implementing six sigma through the survey of blackbelts of Korean firms. The bluechip companies in Korea and across the world have already adopted Six Sigma, and it is becoming an integral part of the corporate culture of these companies. In conclusion, the most important factors to the success of six sigma are found to be the leadership of top management, and the compensation/ incentive system. The analysis also shows that the important factors are different in terms of both the process type and implementing stage.
A Study on Relationship of Airmen influencing Airline Flight Quality
Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 95~116
The primary purpose of this paper is to determine the impact of shared values, conflicts and balanced power that reside in the relationships between airline maintenance engineers and pilots who are considered to be core components in operating aircraft. According to the analysis, the higher the shared values, the lower the conflicts, and the more balanced power between those two parties, the higher the mutual trust and job satisfaction levels. It was also found that the quality of flight operation changes depending on the mutual trust and job satisfaction levels. These results clearly show that the quality of flight operation is directly related to the interactions among two parties and feelings for each other in an environment where mutual dependencies are highly required.
A Case Study on the Assessment Method for Quality Circle as Knowledge Activity
Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 117~126
In order to maximize the effect of TQM in the Korean industry, quality circle activity as a bottomup management should be expanded and revitalized. Quality circle activity can be regarded as a kind of knowledge activity where new knowledge is created and knowledge is shared in the economy. This paper proposes new metrics of intangible effect as knowledge assessment focusing on the intellectual capital aspect of quality circle activity, that may be useful for revitalizing quality circle activity from viewpoints not only of financial effect but also of intellectual capital aspect. New metrics of intangible effect consist of two factors： the intellectual capital effect and the intellectual maturity effect. In order to test the validity of new metrics, a case study of 11 companies was done. The result of the case study is that two factors as an intangible effect of quality circle activity should be evaluated to identify the total effect of quality circle activity correctly.
Development of R＆D Standard Processes for E Research Institute
Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 127~149
With the rapid change in today's R＆D environment and the enlargement of the expected quality level for R＆D outcomes, it has become increasingly necessary to effectively define the R＆D standard processes tailored for our organization and projects. To meet this needs, we defined the R＆D standard processes based on the standards for systems and software engineering and our traditional work methods and applied them to our ongoing projects. We will improve our defined R＆D standard processes continuously by monitoring of the processes and the feedback of the application results. In this paper, we introduce the R＆D standard processes developed by E Research Institute and the requirements and approaches used for their development. We compare our defined R＆D standard processes with ISO/IEC 15288 which is the first international standard for systems engineering.
Selecting on the Preferred Alternatives of MADM with thesmallerthebetter or thelargerthebetter Characteristics using SN Ratios
Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 150~163
The purpose of this paper is to propose an interactive method using the concept of SignaltoNoise (SN) ratios and cutting ranges for selecting the most preferred alternatives of Multipleattribute DecisionMaking(MADM) with thesmallerthebetter or thelargerthebetter characteristics. In this method the decision makers could make a grouping of attributes by their priorities. This research is based on the assumption of an equality between the attributes of MADM with the characteristics of Taguchi method. As a result, this interactive method could transform the characteristic value of Taguchi method into the size of SN ratios which are relatively easy to understand by decision makers.
Bootstrap Confidence Intervals of the Process Capability Index Based on the EDF Expected Loss
Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 164~175
This paper investigates bootstrap confidence intervals of the process capability index(PCI) based on the expected loss derived from the empirical distribution function(EDF). The PCI based on the expected loss is too complex to derive its confidence interval analytically, so the bootstrap method is a good alternative. We propose three types of the bootstrap confidence interval; the standard bootstrap(SB), the percentile bootstrap(PB), and the acceleration biasedcorrected percentile bootstrap(ABC). We also perform a comprehensive simulation study under various process distributions, in order to compare the accuracy of the coverage probability of the bootstrap confidence intervals. In most cases, the coverage probabilities of the bootstrap confidence intervals from the EDF PCI turned out to be more accurate than those from the PCI based on the normal distribution. It is expected that the bootstrap confidence intervals from the EDF PCI can be utilized in real processes where the true distribution family may not be known.
On the Economics of Quality Improvement Activities
Won, You-Dong ;
Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 176~183
The concept of cost of quality has become important economic measures of quality issues for several decades. Most of the research to date has focused on the problem and solution under static business conditions. However, some researchers have found that prevention cost of COQ is one of the expenses of investment and the payback will be shown by the improvement of product quality. These approaches have considered cost of quality issues based on a time factor. It means that there is a tradeoff between prevention/appraisal costs and failure costs. Based on a capital budgeting approach, this research reviews the economics of quality improvement activities and proposes the decision criteria to justify quality improvement activities.
Research about Integrated System construction design of ISO 9001；2000, KS and Product Safety Management by PL(Product Liability) law practice
Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 184~193
PL has been developed centering around England and America. Recently many countries are introducing PL system changing the world a single economic bloc based on the rapid development of Technology and Economy. This paper is studied with related literatures and theses, organizational consulting cases within the framework of the firm as the central operating bodies of PL system. In the past, Some papers about System Integration which was operated as a same Certificate System and enacted in a single organization, was studied and presented. But most of papers was a theoretical study related model and conception. In this situation Government supports PSMS of a single system at government expense to 100200 companies for improving organizational confrontation ability of PL this year. This paper proposed a design and effect of Integration system model based on the analysis of ISO 9001：2000, KS, PSMS and ISO 14001. The integrated system has the following three distinctions. Firstly, KS is a national establishment, national leading certification and forcing standard. Secondly, ISO 9001：2000 and ISO 14001 are an international organization's establishment, nonofficial certification and optional standard. Finally, PSMS isn't a national law and forcing matter. And it isn't the concept of certification but the operational system by itself. Also if a lawsuit by defect is happened, it is very dangerous. This paper, which is integrated by four management systems and has many consulting cases, is the first in this department and is different from others. Also If people has the basic knowledge about management system, they can directly connect it to the organizational system according to this paper's guidance. It is very good result in this study because the law of PL is executed now.
Test of Exponentiality in Step Stress Accelerated Life test Model based on KullbackLeibler Information Function
Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 194~202
In this paper, we propose goodness of fit test statistics for exponentiality in accelerated life tests data based on KullbackLeibler information functions. This acceleration model is assumed to be a tampered random variable model. The procedure is applicable when the exponential parameter using the data from accelerated life tests is or is not specified under null hypothesis. And we compare the power of the proposed test statistics with KolmogorovSmirnov, Cramer von Mises and AndersonDarling statistics in the small sample.

Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 203~218
The ongoing debate over IT productivity has revealed paradoxical effects of IT. This study proposes that IT business value is paradoxical structured. IT impacts are not easy to generalize according to one perspective or paradigm. This study assumes multiplicity in the phenomenon of IT value and explores effects of these multiple interpretations. The study seeks to understand organizational performance. Hypotheses are developed to test the relationship between competing interpretations of IT value and organizational performance. The purpose of this study is to determine whether or not senior managers perceive IT value on the basis of divergent managerial value frames.

Twodimensional warranty data can be modelled using two different approaches： twodimensional point process and onedimensional point process with usage as a function of age. The first approach has three different models. First of all, bivariate model is appealing but is not appropriate for explaining warranty claims. Next, the rest of the two models (marked point process, and counting and matching on both directions independently) are more appropriate for explaining warranty claims. However, the second one (counting and matching on both directions independently) assumes that the two variables (variables representing the twodimensions) are independent. Last of all, onedimensional point process with usage as a function of age is also promising to explain the twodimensional warranty claims. But the models or variations of them need more investigation to be applicable to real warranty claim data.

A preferencebased design metric in dynamic robust design
Journal of the Korean society for quality management, volume 31, issue 4, 2003, Pages 239~246
Dynamic robust design has been regarded as the most powerful design methodology for improving product quality, Dynamic SN ratio adopted in dynamic robust design combines two major quality attributes, the variability around the linear function and the slope of the linear function, into a single design metric. The principal shortcoming associated with the dynamic SN ratio is that the metric is independent of designer's preferences for the quality attributes due to priori sets of attribute tradeoff values inherent in it. Therefore, a more rigorous preferencebased design metric to accurately capture designer's intent and preference is needed. A new design metric that can be used in dynamic robust design is proposed. The effectiveness of the proposed design metric is examined with the aid of a demonstrative case study and the results are discussed.
