최근 Enterprise Architecture(EA)에 대한 관심이 매우 높아지고 있다. 공공분야 뿐만 아니라 민간분야에서도 정보화 노력에 아키텍처의 개념을 도입하려 하기 때문이다. 그러나 실제로 이들 조직에서 아키텍처의 개념을 도입하려는 노력은 매우 다양하다. 즉, 아키텍처 도입의 목적, 범위, 접근 등의 관점에서 매우 다양할 뿐만 아니라 시대에 따라 변해오고 있다. 이러한 아키텍처 도입의 다양성은 아키텍처의 본질적 모습에 대해 많은 혼란을 초래하고 있다. 최근 이 EA의 도입이 가시화되고 있는 실정에 비추어 이 EA의 개념적 실체를 보다 분명히 할 필요가 있다. 따라서, 본 연구에서는 현재 수행된 EA 산출물을 분석해봄으로써 EA 노력을 체계적으로 분류하고 이들 노력의 특성을 밝히고자 한다. 이러한 연구결과는 EA를 보다 정확하게 이해하고, EA 도입 프로젝트의 방향을 설정하는데 기여를 할 것이라고 본다.

The utilization of the Mobile Government system is having more than a few challenges including complexity of different mobile technologies, determining interoperability among existing systems and infrastructures, and establishing services with secured networks. To get over those challenges, integrated standard, innovative and comprehensive system architecture is required by the M-Government. Hence this study proposed reference EA framework for M-Government system in order to avoid unnecessary duplication of infrastructure deployment and integrate services among different government instructions. The study based on literature review, and current infrastructure and mobile network situation for delivering Government services of Mongolia. The study recommends innovative m-Government system framework used EA, and scope covered mobile service delivery area centered on G4C and C2G perspectives. The Federal Enterprise Architecture Framework has used in this research, and the proposed system service architecture defines the interoperable standards, infrastructure components, applications, and technologies for government institutions in Mongolia to aid interactions necessity among them to provide m-Service.

Refining the monitoring and evaluation reporting is an important thing in e-Government. Indonesia which has had e-Government roadmap since 2000, has not had the systematic mechanism to monitor and evaluate e-Government in which the report can be easily accessed by the public and used to be the best practice to improve other e-Government implementation. Enterprise architecture (EA) has the major objective to straighten an enterprise to its necessary requirements. It can be used to propose the required system and that was the purpose of this paper. It was started by reviewing the literature about e-Government monitoring and evaluation, using quality of service as the means, and understanding TOGAF as one of EA framework. The second step was comparing EA and the evaluation of e-Government in Korea and Indonesia to get the best practices. And the last step was creating EA for the monitoring and evaluation reporting system based on Korea and the literature reviewed. It is expected that the formulized EA can be a tool to improve e-Government implementation in Indonesia.

Architecture framework (AF) is a guideline to define components needed to develop and operate enterprise architecture (EA), and to define relationships among the components. There are many architecture frameworks to operate EA of governments and businesses such as Zachman framework, DoDAF, TOGAF, FEAF, and TEAF. DoDAF is the most representative AF to support the development of the EA in the military domain. DoDAF is composed of eight viewpoints and 40 views that are affiliated with the viewpoints. To develop an AF for a specific goal, system architects decide a set of views. Furthermore, they determine data that are needed for a view modeling. However, views and data in DoDAF are structurally inter-related explicitly and/or implicitly. So, developing an AF for a specific goal is going to be a project to be carried out over a long haul. To reduce the burden of its development, in this paper, we develop ONT-SAF (Ontology for DoDAF) that can infer inter-relationships like referential and transitive relationships and the sequences among the views. Furthermore, to promote reusability and consistency of the views and the data within an AF, we adopt the view-data separation strategy. ONT-DAT contains classes like 'viewpoint', 'view', 'data', 'expression method', and 'reference model', and 11 properties including 'hasView.' To prove the effectiveness of ONT-SAF, we perform a case study.

기업의 업무을 지원하고, 조직의 방향을 유도하는 정보 관리시스템에 있어, 전통적인 정보기술 관리에 대한 방법이 개발자 중심의 산출물과 고립된(Standalone) 데이터 처리의 문제점을 나타내고 있다. 이로 말미암아, 고비용, 저통합성으로 인하여 변화하는 기업 내외적인 경영환경에 대처하는 기반구조 변경이 어려운 실적이고, 임기 응변적이고 벤더 중심적인 시스템 개발에 통합성과 업무와 정보시스템간의 얼라이먼트에 문제가 발생하고 있다. 이러한 문제를 해결하기 위하여 ITA를 기업에 적용하여 전사적인 경영과 정보기술간의 통합성과 변화하는 환경에 유연한 적응의 필요성이 대두되기에 이르렀다. 이에 대한 문제점을 해결할 수 있는 경영과 조직에 아키텍처 프레임워크를 구축하여 경영환경의 변화에 따른 능동적인 시스템의 변화관리를 해야 한다. 이에 따라 본 논문에서는 ZachmanFramework,IndexFramework을 소개하고 이들 Framework과 TOGAF를 비교 분석한 다음 향후 기업에 맞는 ITA를 구축하는데 있어 TOGAF의 아키텍처 프레임워크의 활용방안을 고찰하려 한다.

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.

Many government offices have been proceeding a development of Enterprise Architecture(EA) according to apply Government-wide Enterprise Architecture'. Each office and working-level officials have had a hard time because of no guides related to a EA development method such as the Framework, Standards, Principle, Reference Model, Etc. This paper propose a method for developing e-Government Enterprise Architecture considered a characteristic of public institutes through analyzing existing cases. The method for development e-Government EA includes the EA Performance Management Model to monitor objectively each office's long-term business promotion because the e-Government EA development is a job of long duration and cooperation with many institutes. This method also combines the EA Change Management Activities for the officials to improve general knowledge about EA's idea and EA's value, etc. We show the EA case study of the Ministry of Government Administration and Home Affairs to demonstrate feasibility of our approach. As a result, public offices will carry out their BPR(Business Process Re-engineering) and ISP(Information Strategy Planning) more efficiently based on this EA development method.

Traditional information systems in the Ministry of National Defense(MND) are insufficient about interoperability between all kinds of them. Also there is no the applicable architecture framework to develop information systems. The Architecture Framework(AF) is to provide guidance for describing architectures for both warfighting operations and business operations and processes in the MND. Therefore, in this paper we propose the MND AF to develop and manage information systems in the MND.

1980년대 후반 국내에 정보시스템 감리 제도가 도입된 이래 그 효과성이 가시적으로 입증됨으로써 감리의 필요성에 대한 인식이 높아지고 있고, 공공기관 뿐만 아니라 민간기업에서도 감리를 시행하는 사례가 늘어가고 있다. 그러나 정보시스템 구축 프로세스에 근본적인 개선이 이루어 지지 않는 한, 감리만으로는 정보시스템 구축 프로세스나 구축된 시스템의 품질향상에는 한계가 있기 마련이다. 이 연구는, 기존의 정보시스템 프로세스의 문제점을 개선하고, 전사적인 정보화활동 관리가 가능하도록 지원하는 엔터프라이즈 아키텍쳐(EA)의 특징을 정리하고, EA에 기반한 감리프레임웤을 제시하였다 EA기반의 감리 프레임웤은 조직의 정보기술 활동이 경영전략과 업무 프로세스와 연계되도록 평가, 권고, 조정할 수 있는 유용한 수단을 제공할 수 있을 것으로 판단된다.

Korean government has operated EA by the act on efficient introduction of information system and operation, etc. But the evaluation system for EA and the criteria don't prepare well. Particularly, There is no model for EA performance measurement and the way is insufficient. In this study, we derived 8 areas and 17 criteria for the performance evaluation based on the Performance Reference Model of U.S FEA and Korea. And we also derived 8 areas and 10 criteria for it based on the OMB EA Assessment Framework and the EA maturity model in Korea. We propose the performance evaluation model of the five areas that consists of the business performance, customer performance, process, human resource and the technology for EA performance evaluation. To verify the model, we applied the model to three organizations and evaluated EA performance. In addition, we compared the performance result with the performance evaluation area of EA maturity model of Korea to verify the result. We also analyzed the criteria of the proposed performance evaluation model with the current EA maturity model and Performance Reference Model of Korea. As a result of the evaluation, we verified of the proposed performance evaluation model, too.
