Recently, Enterprise Architecture (EA) has emerged as the important keyword in both private and public sectors. With this phenomenon, there are tremendous need for the measures of EA functions, one of the key EA research variables, to provide academic insights and accumulate research findings in this area. Thus far, multiple definitions and concepts for EA functions exist, causing confusion among observers. Thus, in order to clarify the conceptual meaning behind the term "functions of EA" once and for all, this study reviews previous literature and provides conceptual definition. Then, we identify 24 items and rigorously develop and validate the measurement instrument for EA functions, which results in five domains: Infrastructure Systemization, Integration Management, IT Governance Support, Development and Operation Management, and Investment Management.

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.

본 연구에서는 조직에서 ITA/EA가 기여하는 기능이 무엇인지 그에 관한 측정항목들을 도출하였다. 또한 조직의 IT거버넌스가 왜 구축되고, 구축효과는 무엇으로 평가할 수 있는지 측정항목을 탐색적으로 도출하였다. 그리고 설문조사를 바탕으로 상호간의 영향관계를 통계적으로 검증하였다. 분석 결과, IT거버넌스 영역중 IT자원 및 성과관리와 IT프로세스 관리에는 ITA/EA의 업무프로세스 지원과 투자효율화 요인이 유의한 영향을 미치는 것으로 나타났으며, 마찬가지로 IT서비스관리에는 업무프로세스 지원, 투자효율화, 인프라체계화 요인이 영향을 미치는 것으로 나타났다.

Today, IT governance has also become a subject of attention along with recent technologies such as ITSM (IT Service Management), PPM (Project Portfolio Management) and Compliance. At the national level, the market is fairly recent. and therefore, lacks detailed research in the field. Models specifically related to EIM has not yet been presented to this day, hence, firms that are considering EIM as a potential part of their information management system may fall into a state of disorder in the process of its implementation. To this end, this research attempts to construct an IT governance model for EIM based on existing models, surveys and interviews. In particular, E-discovery has been applied as means of protecting information assets and its use as evidence. In addition, by applying the research model to a particular global firm and then assessing its documentation management system, the overall feasibility of the research model has been tested.

The performance of Enterprise Architecture (EA) in the Korea's public IT domain produces mixed results and responses. On the one hand, EA earns positive remarks and enthusiasm as a central government-wide IT governance framework with its significant IT budget saving records. At the same time, however, the response to EA at the department and agency level is tainted with disappointment, fatigue, and reluctance. This essay suggests that this is perhaps caused by the sterile lackluster concept of EA Business Architecture employed in the current EA practice of the enterprise. The possibility for liberating and reviving the concept of EA Business Architecture is explored. Various conceptual axes and branches of EA Business Architecture are identified based upon extensive EA field experience and observations, and discussions are made on how the concept of EA Business Architecture can be expanded and amplified on those conceptual axes and branched. The resulting EA Business Architecture conceptualization is consolidated into an illustrative typology for EA Business Architecture. In the end the theoretical and practical implications of the research are discussed along with its contribution and limitation.

기업들은 정보기술 리스크(IT Risk)에 대하여 어떻게 대처하고 있을까? 금융기관이나 공공기관은 태생적으로 이미 위험관리를 적극적으로 수행하고 있다. 정보기술에 대한 위험관리도 지난 10년동안 전산망 마비, 해킹 사고, 디도스 공격, 고객정보 유출 등을 겪으면서 적극적으로 대응해 왔다. 특히 2011년 농협사태는 IT 성과보다는 IT 보안을 훨씬 중요하게 보는 계기가 되었다. IT 보안 인력과 예산이 대폭 강화되고 망분리 사업이 추진되는 것이 대표적인 사례이다. 하지만 그동안 IT 위험관리는 특정 기술에 대한 사전 대응 및 사후 대응 강화에 집중되었다. 현재 IT 위험관리는 단편적 관리에서 종합적 관리로 전환되고 있다. 최근에 많은 기업들이 전사 차원의 정보기술 리스크 거버넌스(IT Risk Governance) 체계를 구축하고 있거나 구축하는 계획을 갖고 있다. 하지만 아직도 IT보안은 전사적으로 통합되지 못하였으며, IT 위험관리 프로세스는 조직에 내재화 되지 못 하였고, IT 성과관리와 연계성은 고려하지 못하고 있다. 본 논문에서는 IT 관리와 기술을 효과적으로 연계하기 위하여, 그리고 IT 성과와 IT 위험을 균형되게 관리하기 위하여 엔터프라이즈아키텍처(EA: Enterprise Architecture) 활용을 제안하고자 한다.
