The Korean military is aware that EA(Enterprise Architecture) is an important tool for transforming national defense and building Korean NCW, being developing the Ministry of National Defense Enterprise Architecture(MND-EA). However, unlike the importance of MND-EA, they are building MND-EA without the explicit EA governance system Many researchers have emphasized that it is difficult to develop the useful EA without EA governance. In this study, we present the EA governance framework for implementing the effective MND-EA. Through the investigation of the state of EA development and EA governance of home and abroad public institutions, we recognize the importance of EA governance, identifying the EA governance components. We set up the basic governance model consisted of principle, organization and process, designing the MND-EA governance framework by mapping the model to governance scope and target. The proposed governance framework provides direction for explicit and formal MND-EA governance system.

In this paper, the function factors contributing to ITA/EA functions in their organizations, are suggested. Also the reasons to the construction of IT governance system and their effects on the their organizations are discussed and the relationships are verified by empirical model. From the survey, the data of the 227 respondents were collected and regression analysis was performed for validating the research model. ITA/EA functions consist of the IT infrastructure systemization, ITA/EA business process support, IT investment efficiency factors. And the factors of IT resource and performance management, IT process management, IT service management are included to IT governance. The main analysis results described significantly are shows as follows. At first, IT resource and performance management factor is effected by the ITA/EA business process support factor and IT investment efficiency factor. In similarly, IT service management factor is also affected by the factors such as ITA/EA business process support, IT investment efficiency, and IT infrastructure systemization. In additional analysis, IT investment efficiency factor in official sectors, ITA/EA business process support factor in private sectors respectively are described as the significant factors on the IT governance.

In this paper, we brought some influence factors of what the function contributing by ITA/EA in organization is. Also, we verified statistically the impact relation in mutual on the base of questionnaire, extracting in investigation the factors of why the IT Governance of organization is building up, and by what the effect of building up is estimated. In result of statistical analysis based on the 223 case of organizations, it appeared that the infrastructure management, decision making enhancement, and IT process and service functions are the contributing factors on the IT Governance.

The purpose of this research is to propose a practical guideline for activating EA which has been operated in the public institutions. For this purpose, how EA is being operated in the public sector, was analyzed from the viewpoint of IT Governance and on the basis of the result, key activities for EA managers could be developed. The key activities were also compared between the two different groups in terms of EA Maturity Level and the difference in the key activities between the two were examined. As a result, it was found that the use of EA has effect on building and improving IT management systems. It is suggested that the Relational Mechanism should be better understood and recognized as necessary activities for activating EA. In addition, the higher the level of EA maturity is, the more likely such various effects as the enhancement of IT management system, user satisfaction, IT utilization, and the improvement of business can be produced. This result could be interpreted that such desired outcomes of EA could be realized only when EA is actively utilized.

EA, efficient and hierarchical Information Resource Management(IRM) tool of Korean public agencie is one of the core of carrying forward the e-Government initiative. The objective of the paper is to study empirically whether using EA Governance for Controlling EA is related with their EA competency or not. the 190 person in charge of Information System service division are included for analysis. The various hypotheses established are validated by structural equation in SPSS and AMOS 18.0. The results shows that EA management and EA utilization of EA competency level was affected by EA Function, EA Organization and EA Human Resource of exogenous variable EA Governance but EA implementation level was not affected by EA Organization and EA Human Resource. also we investigated that the EA management level of endogenous variable EA competency was affected positively by EA implementation level and the EA utilization level of was affected positively by EA management level by stages.

현대의 조직은 급격한 업무 환경의 변화와 극심한 경쟁에 대응하기 위하여 정보기술에 상당부분 의존하고 있다. 업무 체계가 다양하고 복잡해지면서 이들 체계 간의 연계를 효과적으로 하여 조직의 전략들 달성하는 것이 중요하며, 또한 업무의 민첩성과 유연성을 확보할 수 있도록 정보체계를 구축하는 것이 필요하다. 이를 위하여 전사적 아키텍처(EA)와 서비스 지향 아키텍처(SOA)가 각광을 받고 있으나, 이들은 일회성 프로젝트로 추진하여서는 섬과를 얻을 수 없으며, 지속적인 관리가 필요하다. 이를 뭐하여 EA 거버넌스와 SOA 거버넌스가 필요하다. 이들 간의 어떤 관계가 있는지를 고려하며 어떻게 구축할 것인가를 설명하였다.

Enterprise Architecture (EA) is known as a means to solve IT management problems. In 2005, the South Korean government introduced it and required each agency to develop a variety of architectural products. Such an early-stage EA effort turned out to be not very effective because those products were hardly of use for pan-government IT governance. Realizing these problems, the Lee Myung Bak government has decided to change its direction so that EA products would also be utilized at pan-government IT decisionmaking. After reviewing the early stage of EA effort, we in this study describe such a transition. Future directions of EA efforts are also discussed at the end.

In the aspects of existing cultivation and management of forest resources, national forest informatization has been promoted so that the public can use the resources and so that efficient and systematic cultivation and management of forest resources can be performed constantly. In particular, even though forest informatization has been attempted a lot despite the distinct characteristics of forest, the attempts have achieved little effects. Typically, many of the internal work systems of Korea Forest Service have been built for the purpose of collecting top-down data in the main office rather than the actual work site, and also, from the aspects of use by the public as well, various contents have been provided by the persons concerned, so useful information has not been able to be transmitted systematically. Therefore, Korea Forest Service has promoted IT governance concept and EA-based informatization as a way to solve enterprise problems and also reinforce work and service in the existing system to promote the project to build the foundation of national forest informatization. Based on this, this study suggests chief challenges or implications.

The study focuses on EA experiences of Korea in public sector in terms of three distinguishing periods: preparation, adaptation, and utilization. Analyzing those experiences would lead to understanding of EA performance in Korea, and to derivation of future policy directions. EA efforts of Korea shows results in several areas, especially in prevention of duplicative investments, savings in IT expenses, and optimization of information resource management. The study suggests sustainable strategy for futre EA growth.

Korea has been ranked at the top consecutively in UN e-Government Survey. This fact reflects consistent efforts by public institutes in Korea. However, there were some duplicate efforts and inefficiency in the investment into IS(information systems). In other words, management and decision making on e-government have yet to improved. Accordingly, governmental institutes have long been promoting policies for EA in order to carry out and manage effectively IT projects including the e-Government projects. EA is being regarded as a means to facilitate IT Governance for systematic management of IT projects, A major objective is to firmly establish the decision making process for IS investment through EA, since the each institute is a large organization with so complicated and specialized demand for IS. As a result, systematic decision making is becoming quite difficult. Thus, this study attempts to identify different types of IT investment decision making and to figure out the relationship between the decision types and the organizational performance of public institutes where EA was implemented.
