The necessity of research for EA service and performance is surfacing while nation-level and individual agency level performances utilizing Government-wide EA information. In this study, performance model for EA service has been developed categorizing characteristic elements of EA as service. And weight differences between quality items that constitute performance model have been calculated using AHP analysis method. To achieve the stated, SERVQUAL applied performance model for EA service has been developed working through logical reasoning and a broad range of theoretical studies concerning EA service. Moreover, relative weight differences between quality items that constitute the model have been calculated. The results of weight analysis find that importance differences between quality items in order of significance are as follows: EA administrator > EA information > EA education > EA policy > EA operating system. This study, as the nation's first research to graft the public-sector EA service onto SERVQUAL Model that is capturing remarkable attention, has considerable practical and theoretical implications.

Korea has won 3 times in a row in the evaluation of e-government services in 2014. And the last year, the government-EA has been awarded the UN Public Service Award. Because of the development and execution of personalized integrated services based on the government-EA, Korea has won the two award from the UN. EA has been selected and proceeded as one of the 31 e-Government projects in early period, in 2005 the law which public sector must adopt the EA for efficient informatization had been enacted. Many public agencies in which actively utilized to derive such as internal and external performance through the EA. On the other hand, in the last 10 years, some public agencies have still been as recognized level of management in the EA. In this study, the main purpose is that to find out what is a major factor for successful use and result of EA, what is the EA success Model and how to examine it. To do that, this study will study the related prior research such as EA services, information systems success factors, performance measures, and develop the success model for EA and then examine the model. This study will contribute great implications in practical and theoretical in EA success model because this is the nation's first research that SERVQUAL model and the IS Success Model(DeLone & McLean 2003) has been combined and examined.

Despite the increasing importance of information technology in firms, the extent to which IT governance are established varies widely across the firms. To perform desirably the role of IS needed in most companies, high level of IT governance and the effective management should precede. However, the impacts of such activities and management on the IT governance have not been empirically examined in depth until now. Thus, building on the theory of governance and the institutionalization, the research model and the hypotheses of the study were formed and then empirically tested. The study used a survey of senior IT managers from 108 firms in order to examine hypothesized relationship among the following constructs: strategic alignment, IT governance committee, IT planning, EA, PMO, SLM, IT compliance, incident management, IS effectiveness, visibility, and corporate performance. A structural equation model is developed by using LISREL to assess the relative effects and interrelationship among these constructs. The results show that strategic alignment has positive influence on IT governance committee and IT planning. IT governance committee, IT planning, SLM, incident management from IT governance activities have positive effects on IS effectiveness, whereas IT compliance has a negative effect on IS effectiveness. Visibility is positively influenced by IT planning, EA, SLM. IT compliance, and both IS effectiveness and visibility have positive effects on corporate performance.
