Enterprise architecture is a business transformation effort. In an effort to assess an organization's EA effort and to identify complementary measures, most of countries utilize an EA maturity model. In Korea, the EA maturity model v2.1 has been used for this purpose. Since some limitations in the model were reported recently and there was much change in EA-related policy or approach with the advent of the new government, the need of modifying the current model has occurred. In this regard, our paper proposes an improved EA maturity model. The new model was developed through a series of systematic analysis such as an in-depth comparison of existing EA models, elicitation of alternatives for each decision-making element, and interviewing of experts.

장기간동안 여러 기관의 협력을 통해 이루어지는 전사적 아키텍처(Enterprise Architecture, EA)의 특성상, 기관에서 EA를 도입부터 운영 및 정착, 그리고 고도화시키기 위해서는, 조직의 EA업무 수행 능력을 평가하고 개선하기 위한 적합한 EA기준이 필요하다. 하지만 국내 EA에 대한 연구는 아직 도입단계이기 때문에, EA조직의 수준측정을 위한 EA성숙도모델에 대한 연구는 활발하지 않다. 이러한 상황에 따라, EA조직의 수준측정을 위한 EA성숙도모델에 대한 연구는 활발하지 않다. 이러한 상황에 따라, EA성숙도 모델을 정의하고, 측정을 위한 평가항목과 해당 지침을 제시하고자 한다. EA성숙도 모델은 CMMI의 연속형 모델을 참고하여, EA성숙도 모델의 선진사례 분석과 정부 '정보시스템의 효율적 도입 및 운영 등에 관한 법률'을 기반으로 하여 총 4개영역 15개평가요소를 정의하였다. 성숙도 단계는 인식부터 최적화 단계까지 총 5단계로 정의하였으며, 이 중에서 첫 번째 단계인 인식단계의 평가항복별 지침을 제시하였다. 이렇게 각 항목에 대한 측정 대상자들의 이해를 높임으로써 좀 더 정확한 성숙도 평가 결과와 이를 기반으로 EA고도화를 위한 좋은 기준을 제시하고자 정의하였다.

Networked enterprise (NE) is an organization of independent companies that collaborate with each other temporary or permanently for accomplishing common goals. The USA and EU have been developing principal concepts, techniques, and solutions to enhance the competitiveness of traditional industries including small-and-medium enterprises (SMEs). In Korea, however, implementation as well as R&D of NE is very few, which we believe comes from lack of understanding on Its meaning and lack of effective information systems for it. This paper is to suggest an Enterprise Architecture (EA) framework or reference model of NE and an Information Technology Architecture (ITA) of NE. The EA framework will help stakeholder of NE (e,g., policy makers, members of NE, IT solution providers, and researchers) understand structural and behavioral characteristics of NE. The ITA will be used as a guideline of developing information systems for NE that is essential for spreading networked business models, The focus of this paper is not on logical-level design but on conceptual-level modeling of NE. As verification of the suggested framework and architecture is still required, so we'll apply them to various manifestations of NE, e.g., dynamic supply chain, vertical integration of extended enterprises, and P2P-style virtual enterprises.

Recently a new IT planning effort, Enterprise Architecture (EA), is being carried out by a number of organizations. According to many previous studies, this EA effort intrinsically differs from information systems planning (ISP). In practice, however, it is often performed just like ISP, pursuing identical objectives with just a few more modeling methods. It might lead to a misunderstanding that EA is no different from ISP. In an effort to clarify the difference, we investigate how these two planning efforts differ one from another in richness of architectural description. 19 RFP(request for proposal)s were empirically analyzed to see the difference between EA and ISP in terms of the richness of architectural description.

In a knowledge-information based society, effective management across IT industries, value of information and interoperation are more important than eyer before. Therefore, ITA/EA which helps to plan and manage IT systematically and effectively, was enacted and announced in 2005 and has been considered as an innovative IT management approach. Unfortunately, however, new standardization of ITA/EA has not fully discussed yet. How to successfully apply EA/ITA to IT is considered as the most urgent challenge and this study aims to find out the most effective method. To this end, it was emphasized that training systems for specialized experts must be operated systematically through 'standardization of terms and tasks' and 'standardization of manpower training' and certification of specialty must be newly established. In addition. it was strongly demanded that dual structure caused by mixed concepts between ITA and EA must be eliminated. At the same time. a new model for domestic standardization was suggested so that not only ITA/EA can be recognized as IT engineering but also professional engineers can accept ITA/EA as a scientific field. In summary, this study is intended to propose how to improve information management efficiency through ITA/EA.

본 연구에서는 엔터프라이즈 아키텍처(Enterprise Architecture:EA)의 운영 및 성과에 영향을 미치는 요인으로 EA의 핵심성공요인과 EA 전담조직의 역할을 선정하였으며, 특히 EA 전담조직의 중요성을 증명하고자 한다. 구체적으로 EA 관리 및 운영단계에서의 핵심성공요인을 기반적, 문화적, 제도적의 세 요인으로 분류하였고, EA 전담조직의 역할은 계획관리, 체계관리, 인적자원관리, 정보관리, 위험관리의 다섯 가지 분류로 나누어 각각의 요인이 EA 성과에 어떠한 영향을 미치는지 알아보고자 한다.

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.

정부의 행정 서비스를 보다 효과적이고 효율적으로 제공하는 것은 정부혁신의 핵심키워드이다. 이를 위한 수단으로 정부 공공기관들은 전사적 아키텍처(Enterprise Architecture)를 적극적으로 도입, 활용해야 한다. 전사적 아키텍처란 아직까지도 진화중인 개념으로 해당 기관 정보화 업무의 전 영역을 업무 프로세스(Business Processes), 정보 흐름 및 관계(Information Flow and Relationships), 애플리케이션(Applications),데이터 명세 및 관계(Date Descriptions and Relationships), 그리고 기술 하부구조(Technology Infrastructure)로 구분 짓고 각각을 구조화된 산출물로 정리함으로써 공공정보화의 청사진을 제시한다. 이렇게 구축된 아키텍처 결과물은 기관 내 뿐 아니라 타 기관 EA와의 연계를 통해 상호 운용되어야 하며, 이 과정에서 어휘의미중의성(Word Sense Ambiguation)등 상호운용성 문제가 핵심 이슈로 대두되리라 예상된다. 공공분야로 한정짓더라도 200여 정부부처 EA간의 상호운용성 문제는 정부조직 간 경계를 넘어 통합된 EA정보를 취합, 활용하는 데 있어 가장 큰 장애요인이 되리라 예상된다. 본 논문에서는 온톨로지를 사용하여 각기 서로 다른 EA간 상호운용성 문제를 해결하는 방안에 대해 논의하고자 한다.

Recently, EA has been introduced in the Korean government as a tool for improving both IT management and IT investment. However, EA has been superficially used at the conceptual level without any efforts for facilitating it. As a result, it seems that any substantial outcomes from using EA could be hardly realized. This study suggests EA Service Model as a framework for facilitating the use of EA and then generating benefits. The purpose of EA Service Model is to provide a framework with which information and data can be linked, interconnected and shared in the whole process of IT management. It is expected that EA Service Model will possibly make a contribution to improving IT management. Empirical Analysis shows that key factors of EA Service Model make significant effects on improving the IT management, proving practical value and the validity of the model.
