The Impact of Supplier Involvement, Customer Involvement, and Employee Learning/Training on Product Quality and Organizational Performance
Park, Chul-Soon ;
Journal of the Korean Society for Quality Management, volume 40, issue 1, 2012, Pages 1~14
DOI : 10.7469/JKSQM.2012.40.1.001
This study investigates the impact of supplier involvement, customer involvement, and employee training on product quality and organizational performance. Based on literature review, this study develops hypotheses and tests them by employing a structural equations model. Using survey data of 193 firms from 22 manufacturing industries, this study empirically shows that the activities for supply chain quality management (SCQM) enhance the quality and organizational performance. Specifically, quality leadership is revealed to be an antecedent of other SCQM activities. The most contributable finding is, while the supplier involvement and employee training directly enhance the organizational performance, customer involvement indirectly improves it via quality performance.
A Study on the Construction and Analysis of Fractional Designs by Using Arrays for Factorial Experiments
Kim, Sang-Ik ;
Journal of the Korean Society for Quality Management, volume 40, issue 1, 2012, Pages 15~24
DOI : 10.7469/JKSQM.2012.40.1.015
For the construction of fractional factorial designs, the various arrays can be widely used. In this paper we review the statistical properties of fractional designs constructed by two arrays such as orthogonal array and partially balanced array, and develop a quick and easy method for analyzing unreplicated saturated designs. The proposed method can be characterized that we control the error rate by experiment-wise way and exploit the multivariate Student
-distribution. Especially the proposed method can be used efficiently together with some exploratory analysis methods, such as half normal probability plot method.
Corrective Action Strategy based on SWOT Analysis in Service FMEA

Service FMEA may yield several possible corrective actions for each failure mode with large RPN. Corrective actions for each service failure are usually interrelated with the customers and environmental elements of the service system. SWOT analysis can provide an effective way to analyze the inner and outer environmental impacts for each corrective action. In this paper, we suggest a way for selecting and ranking corrective strategy in service operation based on SWOT analysis. Every candidate of corrective action strategy is ranked and evaluated on the basis of the impact factors of the SWOT variables, correlations between possible corrective actions and SWOT variables, and RPNs of service failures. The most desirable set of corrective actions is selected considering the preference score of each corrective action, required resources and budgetary allowance. The proposed methodology is demonstrated with an illustrative example.
Economic Evaluation of Early Detection System for Warranty Issues
Jung, Sung-Hwan ;
Journal of the Korean Society for Quality Management, volume 40, issue 1, 2012, Pages 39~48
DOI : 10.7469/JKSQM.2012.40.1.039
An early detection system for warranty issues periodically collects customers` claim data and automatically reports alarms about emerging issues based on statistical algorithms. It helps companies to reduce an issue definition time and save the handling cost of warranty claims. This paper provides an evaluation framework to validate the economic effect of an early detection system project. For this purpose, we present economical index of a project with explicit formulas such as ROI(return on investment), PP(payback period), NPV(net present value), PI(profitability index) and IRR(internal rate of return) and analyze the sensitivities of the index according to the variation of project input parameters. The proposed analysis framework is expected to be used for evaluating economic values of various system integration projects.
A Case Study for Finding an Efficient M&S Meta Model through Sequential Response Surface Methodology
Kim, Sang-Ik ; Kim, Yong-Dai ; Lim, Yong-Bin ; Choi, Ki-Heon ; Kim, Jeong-Eun ;
Journal of the Korean Society for Quality Management, volume 40, issue 1, 2012, Pages 49~59
DOI : 10.7469/JKSQM.2012.40.1.049
In computer simulation models the output from the computer code is often deterministic, i.e., running the code twice with the same values for the input variables would give the same output. It is discussed why the response surface method with polynomial approximation for the true response function is a good approximation to the computer experiments model. A sequential strategy to find the proper reduced quadratic polynomial model is illustrated with a case study in the military war game computer simulation model.
A study on Mobile SNS Attributes Effects on Information share, Relationship formation, and User satisfaction
Sim, Sun-Hee ; Moon, Jae-Young ;
Journal of the Korean Society for Quality Management, volume 40, issue 1, 2012, Pages 60~72
DOI : 10.7469/JKSQM.2012.40.1.060
This research conducted a survey targeting mobile SNS users in order to see whether mobile SNS attribute( accessibility, usefulness, newness, connectivity) through the medium of information share and relationship formation had a positive influence on user satisfaction. The results of the analysis showed that usefulness and accessibility had a significant influence on information share, while accessibility and connectivity had a significant influence on relationship formation. Information share and relationship formation both had a significant influence on user satisfaction. Based on this research, an angle of approach different from the business transactions and information services offered in existing mobile networks is necessary when corporations provide SNS through mobiles. When considering that the most important part in the use of mobile SNS is the social component, this can be actively used for the development and marketing of SNS services. Therefore, the SNS provider must focus its efforts on finding a method to stimulate user sensibilities in order to increase customer satisfaction and draw out continuous usage.
The Effects of Service Quality and Costs of Power Plant Maintenance Services on Customer Value and Customer Satisfaction
Lee, Jin-Ho ; Kim, Jong-Hoon ; Yoo, Han-Joo ;
Journal of the Korean Society for Quality Management, volume 40, issue 1, 2012, Pages 73~87
DOI : 10.7469/JKSQM.2012.40.1.073
The previous researches have addressed the importance of service quality, customer perceived value, and customer satisfaction, but the precise nature of the interrelationship that exist between these constructs still remains a key issue. This study extend the previous researches by developing a conceptual framework linking all of these constructs, additionally including service costs and customer expected value, in a business-to-business setting. The hypothesized model indicates that delivering high quality and lower costs service can create superior customer value and results in higher customer satisfaction. The authors test the hypothesized model on data obtained from power plant operators using structural equation modeling. The results suggest that service quality displays a stronger potential for creating customer value than costs consideration. In addition, the results reveal that managing the customer expected value is important for obtaining higher customer satisfaction.
Joint Optimization of Age Replacement and Spare Provisioning Policy
Lim, Sung-Uk ; Park, Young-Taek ;
Journal of the Korean Society for Quality Management, volume 40, issue 1, 2012, Pages 88~91
DOI : 10.7469/JKSQM.2012.40.1.088
Joint optimization of preventive age replacement and inventory policy is considered in this paper. There are three decision variables in the problem: (i) preventive replacement age of the operating unit, (ii) order quantity per order and (iii) reorder point for spare replenishment. Preventive replacement age and order quantity are jointly determined so as to minimize the expected cost rate, and then the reorder point for meeting a desired service level is found. A numerical example is included to explain the joint optimization model.
