Relationship between Target Costing Practices and Organizational Performance : An Empirical study
Journal of the Korean society for quality management, volume 31, issue 3, 2003, Pages 1~18
Target Costing research has a long history in the study of management control systems. However, there is very little published empirical analysis studies on Target Costing. This study investigate the impact of Target Costing practices on organizational performance. This study uses survey responses from executive at 125 Target Costing practicing firms to better understand the benefits that firms have experienced through Target Costing adoption and whether a more comprehensive implementation is worthwhile. The research results demonstrate that Target Costing has a positive and significant relationship with low cost, efficiency of R&D, and interaction facilitation. In particular, there is significant and positive relationship between organizational structure and performance. This study indicate that Target Costing is a vital management strategy to build and sustain competitive advantage.
Building of PSMS in corporate of ISO 9000 certification
Journal of the Korean society for quality management, volume 31, issue 3, 2003, Pages 19~36
The manager of manufacturing industry just not to have known what to do related to the law of product liability(PL) that was put into operation in July 1, 2002. The law of PL is a public law about defective product, which was established in order to compensate consumer's damages of property and body caused by product, to make sound society by the safety products and to take international competitiveness. But the existing civil law has been having clause that compensation to be taken is limited. The law of PL is resolving this limitations and is characterized by the easy relief from damages of defective product. The decision in the case of Green-man has been a precedent since the court sentenced the manufacturer to liability. The law of PL has been in force in 27 countries, including all of the EU countries, Japan, Philippines and China. It has been shown that the corporations which meet the Global Standard, could survive in global competition. The economic effects by the law of PL are the increase of consumers relief production cost by the lawsuits. This paper will recommend more biref method that is able to cover PSMS by use of QMS. It will make domestic corporation improve in the plan, manufacture and sale of products to meet the Global Standard.
A study on the quality management status and performance recognition of enterprises
Journal of the Korean society for quality management, volume 31, issue 3, 2003, Pages 37~61
The purpose of this study is to identify (1) the successful quality management activities of domestic enterprises contribute to enhancing both corporate and national competitiveness and that the corporate and national competitiveness are related each other; (2) and to have the government and the citizens as well as enterprises re-recognize the importance of quality management and encourage them to make aggressive investments on quality management. It was found in this study that the enterprises with quality management scheme showed better performance that those without quality management activities. It was also found that quality competitiveness is a key factor for the enhancement of the national competitiveness, and that although quality improvement is normally realized through efforts of private enterprises (a conventional paradigm), active government support and participation are absolutely necessary for the competitiveness of the nation and industries. Accordingly, the quality management should be recognized not only as part of business improvement activities, but as nationwide activities where public sectors including government enterprises, hospitals, schools, regional governments, media companies and citizens groups are involved. In order to build a high-quality nation in the 21st century, the quality improvement should be realized through concerted efforts of the people, enterprises and the government.
The Methods of the Activation of Korean Private sector-driven Standardization for coping with the Dynamic International Standards
Journal of the Korean society for quality management, volume 31, issue 3, 2003, Pages 62~84
The typical reason of the private sector's increasing share in standardization is that the procedures of official standardization organizations are out of step with the rate of technical development. At today's so fast pace that the success of a technology is decided in the market even before it is standardized, several industry leaders jointly make their draft standard at the early stage of development, which becomes 'De fecto Standard.' To respond effectively to current trends of standardization where the market's decision is thought much of than official standardization procedures, it is necessary to shift from our current public sector-driven to private sector-driven standardization. Therefore, to vitalize the private sector-driven standardization in Korea, there is a need to: Run a standard foundation to secure stable resources for standardization Make information exchange between the govertment and private sector active and policy-making on standards consistent by designating a private organization to cover the roles, policies on standards, and support of the national standardization organization Establish a system to make private sector-driven standards approved as international standards Offer a training program to forster standard experts Publicize the importance of standards Promote standardization forums driven by private businesses, like the Integrated Forum. Maximize the benefits of linking standards and patents Now, Korea is on the threshold of developing into a world-class standard leader, and the private sector-driven standardization should be a stepping-stone for crossing over the threshold. This study is designed to suggest a method of promoting private sector-driven standardization to effectively cope with fast-changing international standards, based on the cases in developed countries.
A study of developing Customer Satisfaction Index(CSI) used for Structural Equation Model(SEM) and applications of customers' decision - focused on the domestic automobile industry -
Journal of the Korean society for quality management, volume 31, issue 3, 2003, Pages 85~97
There are various methods to assess to company's outcome. Among them, the customers satisfaction, which is assessed by customers, is the most important. If the customers satisfaction is measured by the CSI based on the proper reliability and validity, you can apply the result for various marketing methods. Therefore, this study develops a model to assess CSI for an industry, specifically, local automotive industry based on the SEM that is already proven valid through assessing models such as ACSI, KCSI and NCSI. Moreover, this research can be utilized for marketing strategy helping customers to decide as an AHP model, one of the decision making method.
Fuzzy KANO Model: Fuzzy Set-Based Classification of Customer Requirements
Journal of the Korean society for quality management, volume 31, issue 3, 2003, Pages 98~113
Kano model distinguishes three types of customer requirements, namely, one-dimensional quality, must-be quality, and attractive quality. There are a few methods for classifying a given customer requirement into one of the Kano's quality elements. However, the existing methods have a common limitation in that they are based on Kano evaluation table. Kano evaluation table is not always effective for the classification task, and suffers from a significant information loss. This paper proposes an alternative to Kano's evaluation table and a new classification scheme based on fuzzy set concept. The proposed method is illustrated using a case study on the ADSL service.

Journal of the Korean society for quality management, volume 31, issue 3, 2003, Pages 114~125
In this paper, we deal with the problem of modeling of agent-based robot manufacturing cell. Its role is becoming increasingly important in automated manufacturing systems. For Object Oriented & Queueing Petri Nets (OO&QPNs), an extended formalism for the combined quantitative and qualitative analysis of different systems is used for structure and performance analysis of mobile robotic cell. In the case study, the OO&QPN model of a mobile robotic cell is represented and analyzed, considering multi-class parts, non-preemptive priority and alternative routing. Finally, the comparison of performance values between Shortest Process Time (SPT) rule and First Come First Serve (FCFS) rule is suggested. In general, SPT rule is most suitable for parts that have shorter processing time than others.
Statistical Design of VSS
Charts for Monitoring an AR(1) Process
Journal of the Korean society for quality management, volume 31, issue 3, 2003, Pages 126~135
A basic assumption in standard applications of control charts is that the observations are statistically independent. However, this assumption is often violated from processes in many industries. The presence of autocorrelation has a serious impact on the performance of control charts, causing a dramatic increase in the frequency of false alarms. This paper considers a process in which the observations can be modeled as a first order autoregressive(AR(1)) process, and develops (equation omitted) charts with the variable sample size(VSS) scheme for monitoring the mean of this process.
A Study on the Step-by-Step Process for Effective Quality Circle Activities
Journal of the Korean society for quality management, volume 31, issue 3, 2003, Pages 136~159
The purpose of this paper is to propose the effective guidance of Quality Circle(QC) activities. Since 1975, variety of organizations in Korea have widely implemented QC activities for their management systems. The industries have enthusiastically used QC activities and were influenced from them. However, the academics were less interested in this subject, as a result, there were no systematic guidances for QC activities. Thus, in this paper, the effective guidance for QC activities were suggested which were based on the survey from QC proceedings presented in the companies, in the local areas and the national wide contests. As a result, the first main issue is to pick repeated mistakes up during the process period such as unmatched the causes and effects relations in characteristics diagrams, improper selection of important control items in Pareto diagram and so on. Secondly, how to overcome statistics and use them for QC activities. Thirdly, to remind team members about Quality Control 7 tools. Finally, Minitab(Release-13) software has been found that it is not matched with using Korean Standards(KS).
A Study on the Way to Improve Quality of Asset Portfolio Management Using Structural Time-Series Model
Journal of the Korean society for quality management, volume 31, issue 3, 2003, Pages 160~171
Criteria for the comparison of quality of asset portfolio management are risk and return. In this paper a method to use structural time-series model to determine an optimal portfolio for the improvement of quality of asset portfolio management is suggested. In traditional mean variance analysis expected return is assumed to be time-invariant. However, it is more realistic to assume that expected return is temporally dynamic and structural time-series model can be used to reflect time-varying nature of return. A data set from an insurance company was used to show validity of suggested method.
The misusage of statistical methods in Six Sigma projects
Journal of the Korean society for quality management, volume 31, issue 3, 2003, Pages 172~184
Many companies in Korea are paying close attention to Six Sigma to get better business results. And there are numerous success stories on the use of statistical methods in solving problems, improving processes and cutting costs. However, there are many cases in which statistical methods are misused or inappropriately applied. In this paper, the pitfalls to avoid in using statistical methods are discussed. Also the role of statistics in Six Sigma is examined.
On Optimal Replacement Policy for a Generalized Model
Ji Hwan Cha ;
Journal of the Korean society for quality management, volume 31, issue 3, 2003, Pages 185~192
In this paper, the properties on the optimal replacement policies for the general failure model are developed. In the general failure model, two types of system failures may occur : one is Type I failure (minor failure) which can be removed by a minimal repair and the other, Type II failure (catastrophic failure) which can be removed only by complete repair. It is assumed that, when the unit fails, Type I failure occurs with probability 1-p and Type II failure occurs with probability p,
. Under the model, the system is minimally repaired for each Type I failure, and it is repaired completely at the time of the Type II failure or at its age T, whichever occurs first. We further assume that the repair times are non-negligible. It is assumed that the minimal repair times in a renewal cycle consist of a strictly increasing geometric process. Under this model, we study the properties on the optimal replacement policy minimizing the long-run average cost per unit time.
Optimal Periodic Preventive Maintenance with Improvement Factor
Jae-Hak Lim ;
Journal of the Korean society for quality management, volume 31, issue 3, 2003, Pages 193~204
In this paper, we consider a periodic preventive maintenance(PM) policy in which each PM reduces the hazard rate but remains the pattern of hazard rate unchanged. And the system undergoes only minimal repairs at failures between PM's. The expected cost rate per unit time is obtained. The optimal number N of PM and the optimal period x, which minimize the expected cost rate per unit time are discussed. Explicit solutions for the optimal periodic PM are given for the Weibull distribution case.
