Journal of the Korea society of IT services, volume 9, issue 1, 2010, Pages 1~25
Many organizations are facing larger and more frequent changes in the current economic and managerial environment. And what is more, change is supposed to be a business as usual. Considering the importance of change management process and the organizational competency to rapidly and successfully change, in this study the components of change management maturity(CMM) was selected such as the leadership, communication, resistance, people culture factor, methodology, functional group, and change review. And information system performance affected by CMM is confined to the efficiency and effectiveness of information systems. Some results from the verification of research hypotheses and the analysis of the most appropriate model was drawn out. The result of this study can be applied to all organizations which plan to manage more successful change and implement more effective information systems.

Recently, many organizations are actively adopting Enterprise Architecture (EA) as a methodology to manage IT assets and build IT-based business system. However, most existing studies on EA have focused on the adoption stage of EA. Now the research concerning effective management and utilization of EA after adopting EA is keenly required. This study intended to empirically examine how the role of EA operating unit and the EA utilization capability of organizational members impact on EA performance at the post-adoption stage of EA. Based on Resource Based View (RBV), this study proposed the model and the hypotheses describing that the impact of the role of EA operating unit on EA performance is mediated by the EA utilization capability of organizational members. In order to test the hypotheses, the field survey whose respondents were seventy four Korean public agencies which have adopted EA was conducted by means of questionnaire. Data analysis was done with partial least square (PLS), which is a structural equation modeling (SEM) technique that uses a component-based approach to estimation. The results of the empirical analyses showed that the organizational operation ability of EA operating unit significantly influenced EA performance via the EA utilization capability of organizational members, but that EA education and training performed by EA operating unit did not. The results of this study provided a lot of theoretical and practical implications regarding EA management activities at the post-adoption stage of EA to enhance EA performance.

With the improvement of the Information Technology and the change of the business environment, the dependency of business on the Information Technology shows sharply increase. The Information Technology, however, is centered on the support of the technology viewpoint and thus the influence and effect of Information Technology on the business is hardly analyzed. The information system, therefore, requires not only technology-centric support management but service-oriented and systematic introduction of Information Technology Service Management(ITSM). The domestic ITSM market is currently expanding into variety of industries like finance, telecommunication, manufacturing and public service and at the same time the consequent reconstruction process of information system is continuously under way so as to qualify for the ISO 20000 certification. Especially the public organizations rapidly adopt the ITSM, in order to improve the quality of public service together with a goal of realizing the electronic government and of managerial innovation. The existing ITSM still, however, shows the tendency of depending only on the system construction and the management on the visible requirements whereas the overall process is not likely being improved. Hence, this study suggests, focusing on the life cycle of service, the model of ITSM based on Information Technology Infrastructure Library(ITIL) v3 which is appropriate for the public service. We expect, as stated in this study, that our ITSM model shall be widely accepted to the public agencies who promote the advance campaign by setting up the ITSM or reconstructing the existing process.

The purpose of this study is to verify the competence level of IT service companies in Korea from the view point of capability of creating customers value and outcome as an independent companies which have been growing in the captive customers(market) circumstance by performance data analysis and IT specialists survey. This study presents a growth model which emphasis on the importance of the correlation between IT service companies and captive customers. It proves that the captive customers have been being the growth power and motive of the IT service company, because IT service companies have been cumulating the competence for IT service through the service for the customers, and with this competence, IT service companies have been expanding its service out to non-captive market(customers) and got good outcomes as an independent companies. And this study proves that the captive customers who served by the IT service companies which have a higher level of service capabilities have better business outcome. IT service companies contribute to improve the IT level of the captive customers and to make the customers to increase sales by conducting IT projects.

Up to now, a shortage of SW staff has been a threat to providing satisfactory SW services in Korea. Therefore, it is necessary for us to understand factors that satisfy SW personnel and then retain them not to leave their current job positions. Hereafter, we examine whether SW manpower's job satisfaction fully mediates or partially mediates the relationship between the drivers of turnover intention such as satisfaction on IT education, job fitness, fairness of rewards and organizational moods and turnover intention. Using survey data from 745 SW staffs, we found that all antecedents except for satisfaction on IT education have significant impacts on job satisfaction as well as verified that the job satisfaction partially or fully mediates the relationships between job fitness, fairness of reward and organizational moods and turnover intention. Based on our findings, our results allowed us to provide a deeper understanding of the forces on turnover intention by examining the role of mediating effect on job satisfaction.

Journal of the Korea society of IT services, volume 9, issue 1, 2010, Pages 91~111
An efficient industry structure is essential for competitive IT Service industry in a global world. The purpose of this research is to derive a policy direction paradigm for strengthening IT service industry structure. To find an effective policy direction, an in-depth analysis on deep-rooted problems of IT service industry has been conducted. The root-causes of industry problems are found with new perspectives on IT service industry. Past and present policies on IT service industry have been reviewed based on desirable industry behavior. A new policy paradigm and a roadmap for efficient industry policy are suggested. To justify adequacy of new policy direction, global benchmarking has been performed. USA, Germany, and Japan's IT service industry has been reviewed based on global competitiveness and desirable eco-system. And an in-depth analysis has been performed for two big competitors, India and China, The adequacy of the new policy paradigm has been tested, and mostly approved. IT service industry policy needs to be transformed from manufacturing concepts to service concepts, from domestic focus to global focus, from zero-sum policy to positive-sum policy, from supplier focus to market focus, from internal industry itself to co-growth with main industries. etc. The results of this study can be used for policy adjusting and policy making to strengthen IT service industry's global competitiveness and to improve long-term performance of Korean economy. Further in-depth researches with quantitative analysis will be needed to fully justify the adequacy of the derived new policy directions.

Journal of the Korea society of IT services, volume 9, issue 1, 2010, Pages 113~125
Recently, a smart space with Ubiquitous Environment is expanding rapidly due to the development of Ubiquitous Sensor Network. Therefore, more appropriate and intelligent services of the context awareness system is being required. The previous context awareness system can provide a service to the user through the inference only on the current situation. But, it does not handle certain situation properly when the system provides abnormal result. Also it does not have any proper method of generating reliable semantic data from sensed raw data. In this paper, we are trying to solve the problems as the following approaches. First, the system recognizes abnormal result and corrects it by learning feedback from the user. Second, we suggest a method of converting sensed data into more reliable semantic data. Third, we build the system based on an Ontological context model that is capable of interoperability and reusability. Therefore, the context awareness system of our study can enhance the previous system that can generate more reliable context data, can provide more effective inference method, and can provide more intelligent system structure.

Due to the development of information technology and business related to geographical location of customer, the need for the storage and analysis of geographical location data is increasing rapidly. Geographical location data have a spatio-temporal nature which is different from typical business data. Therefore, different methods of data storage and analysis are required. This paper proposes a multi-dimensional data model and data visualization to analyze geographical location data efficiently and effectively. Purchase order data of an online farm products brokerage business was used to build prototype datamart. RFM scores are calculated to classify customers and geocoding technology is applied to display information on maps, thereby to enhance data visualization.

Service industry has become the integral part of economy. And the activation of industry requires a scientific and systematic approach. As one of these kinds of efforts, IBM presented a service model which consisted of strategies, processes, technology, manpower and so on through Service Science. And IBM raised the needs of considering the main issue and methodology of service model's scientific approach. On that account, this study worked out factorial definitions and measurable items by the four components of service model presented by Service Science in order for it to be measured through studies on related literature and interviews of specialists. In order to prepare an opportunity of categorizing the conception of the service model of which character was strongly intangible and of systematically approaching to it, the investigator examined related literature and applied it QFD methodology. Through this kind of redefinition, the investigator concretely conceptualized the service model which was standstill at the level of theoretical approach so far and presented guidelines with which researchers could classify it more concretely. In addition, the investigator tried to present a systematic frame which could be applied to business by working-level officials or decision-makers. Therefore, the investigator expects that study findings will be used as references for the design or implementation of service-oriented business model.

Recently 'full browsing service' is growing rapidly throughout the world. This service allows mobile phone users to access websites using their mobile phone as they do using a PC. Despite the rapid expansion of the mobile phone market, however, criteria or scales for evaluating the new services are being developed slowly and far behind the current demand trends. Thus, this study proposed a customer satisfaction evaluation model for full browsing services through empirical research. The proposed model is expected to derive and suggest key factors that users consider important in full browsing services and those factors can be used in developing marketing strategies for maintaining existing customers and creating new customers.

Though service is recognized as not only a new driver for economy growth but also a source for sustainable value creation, it has been misunderstood in the literatures because of traditional characteristics of service such as inseparability, heterogeneity, intangibility, and perishability. This perspective can be a cause of barrier to approach a service. The purpose of this study is to develop and validate an instrument to measure of the service process. A series of statistical procedures were used to analyze the data, which proved that the instrument is valid and reliable. This study makes a contribution to both academic research and management practice. Theoretically, this study provides a measurement of service process in organizations for identifying service process. In practice, the results of this study will help organizations evaluate their service process innovation.
