Customer satisfaction index measurement and importance-performance analysis for improvement of the mobile RFID services in Korea

Mobile RFID Services will make us recognize the identification code of all kinds of items in which people are interested with the RFID Reader built into a cellular phone. They will also make us search for more detailed information through the mobile internet network.Recently, in Korea, a variety of mobile RFID services are being piloted, and their commercial roll-out is likely to be imminent. The goal of this study is to propose, ahead of the commercial launch of mobile RFID services, a customer satisfaction index model for this service category, and measure customer satisfaction index, so as to derive practical implications for their providers, and pointers related to service improvement. A web survey was conducted on Korean mobile phone subscribers having participated in a mobile RFID pilot program. Using the results of this survey, we tested the customer satisfaction index model we proposed and its hypotheses, by employing a PLS (Partial Least Squares)-based on structural equation modeling technique, and calculated the index. We further conducted an Importance-Performance analysis, to provide implications that may be useful for improving the quality of mobile RFID services.

A BUSINESS MODEL ANALYSIS FOR THE SUPPLY CHAIN CONVERGENT OF SERVICES

In this paper, we explore the merging of supply chains between media and telecommunications as an example of business application of industry convergence. The goal of this study is to provide managerial insight into the various facets of convergence of supply chains so that companies can effectively exploit business opportunities presented by the accelerating process of digital convergence and related technological innovations. In this study, the focus is set on business models, rather than business strategies as such, since digital convergence is an emerging sector that deserves independent attention as a new business concept. We formulated a series of propositions, related to customer value, value network, and supply chain efficiency, using frameworks borrowed from the existing business model literature and value creation theories for Internet business. Managerial implications are discussed and applied to DMB (Digital Multimedia Broadcasting), a new telecom-broadcasting convergence business model, recently introduced in South Korea.

Factors affecting customer loyalty of mobile RFID services in Korea

AbstractMobile radio frequency identification (RFID) services are expected to be launched in full-scale as a new service option in the telecommunications service market following the development of RFID technology and maturation of the IT infrastructure. Importance of customer loyalty has been widely recognized in business marketing for a long time, and the customer loyalty enhancement strategies for mobile RFID services is of significance to telecommunication carriers in terms of new business value creation. This study identifies the factors affecting customer loyalty for mobile RFID services and presents telecommunication service managers with information useful for improving customer loyalty for related new services. The data was collected from customers with some experience in the use of mobile RFID services through an online survey for an empirical analysis. And the collected data was analysed with structural equation model to verify the cause and effect relationship among perceived quality, switchin...

The business value of mobile RFID services in Korea

Korea has studied convergence technology to mount the miniature RFID reader on cellular phone through the mobile RFID forum established in February, 2005 by MIC(Ministry of Information and Communication Republic of Korea) and the relevant organizations. Mobile RFID services will make us recognize the identification code of all kinds of items in which people are interested with the RFID reader built into a cellular phone. They will also allow us to search for more detailed information through the mobile Internet network. Recently, the leading providers of mobile telecommunications in Korea, SKT and KTF, have been providing this as a trial service, and as a result, the commercialization of mobile RFID services will soon be launched. The purpose of this paper is to evaluate the business value for the mobile telecommunications service providers by measuring and forecasting the market value of mobile RFID services with CVM(Contingent Valuation Method), which uses the WTP(Willingness to Pay) of the customer. In Korea, this trial services are as followers: Genuine ginseng verification, U-Portal service, Genuine drug verification, Safe taxi service, Food history service, Korean premium beef verification, Touch book service, McDonaldpsilas touch order service, U-Museum service and so on.

A conceptual evaluation model of the RFID performance using a balanced scorecard

There are twe purposes in this study. One is to help draw objective and reasonable results of performance evaluation by developing and proposing radio frequency identification(RFID) performance evaluation models suitable for public-sector and private-sector. The other is to use the model for pulling and accelating demand for RFID through concrete and measurable evidences of the new technologys benefits. This study developed two models for evaluating the performance of RFID using a balanced scorecard (BSC); one for the public-sector and the other for the private-sector. To determine the most appropriate indicators to capture performance changes resulting from the introduction of RFID for the two sectors, we performed an Analytic Hierarchy Process (AHP) analysis on a set of indicators from the existing literature. The result showed that the most important of the four performance perspectives was the customer perspective for the public-sector, and the financal perspective for the private-sector. Meanwhile, the Key Perfromane Indicators (KPIs) which affected the attainment of organizational goals the most were customer satisfaction, cost reduction, economic effect, and inventory management efficiency for the public-sector, and return on investment (ROI), return on sales (ROS) and customer satisfaction for the private-sector.

A Study of Business Models and Strategic Alliance in the Home Network Industry in Korea: Analysis and Suggestions

In Korea, the home network industry has been the object of great expectations among the government and business community. Thus far, however, it has proved unable to fulfill these expectations. In this study, we categorize three classes of services and five participant industry sectors with regard to Koreas home network industry. We consider that the differences in their business models from these three different participant industry sectors hinder the growth of the home network industry. Hence we analyze business alliance theories for the home network industry to cooperate with each other in order to complement the differences between their business models. We propose five cooperation strategies for the three classes of home network services and two related issues. Finally, we offer some suggestions to help remove the obstacles to business cooperation among the participant industry sectors of the home network industry.

Radio resource requirements in the IMT-2000 network

Summary form only given. Successful implementation of IMT-2000 services will be decided in the market. Therefore, the strategy for the IMT-2000 industry should be planned with the view of the market. Many studies have adopted various estimation methods to measure economic efficiency on IMT-2000 services. The ITU-R forecasted the marketability of IMT-2000 services and introduced a method to estimate service channel requirements and terrestrial spectrum requirements in the IMT-2000 networks in 2010 based on the estimation of wireless transmission parameters. Because most of the huge amount of investment cost of the IMT-2000 services will be allocated to the construction of radio access networks and core networks in particular, this study attempts to provide IMT-2000 industry with the number of service channel and terrestrial spectrum requirements based on ITU-R recommendation in 1999.
