Recently EA(Enterprise Architecture) has been receiving growing attentions again from the public sectors. It is because EA maturity result is reflected to the organization's informatization level and EA maturity ratio has been enlarged. There has been more participation from the Chief Information Officers of the public sectors. EA research in the public sectors has influenced IT environment since the research started in late '90, the legislation work done in '05, and the maturity model developed in '06. However, there are some remaining tasks to solve. EA policy is introduction oriented, its contribution to the consecutive the best UN e-Government rank is limited, and its user-friendly responding system is still lacking. Related research outcomes are rather microscopic focusing only on the models and maturity than implicating on the public policy in a macroscopic manner. In this respect, this study will provide the implication on how EA policy should be. Requirements derived from EA stakeholders and the tasks will be arranged in accordance with its domain, then the performance and tasks will be demonstrated. As guiding EA stake holders and information related officers to setup the EA policy with these results, this study is expected to support information the policy drivers.

Many countries have implemented EA as a core tool for planning and managing IT resources. Due to its importance, there have been many studies for the successful implementation of EA. However because most previous studies simply focused on either a certain time horizon as a cross sectional study or a list of success factors, they failed to raise fundamental issues investigating inherent difficulties or efforts to overcome. This research conducted a case study based on interviews with EA experts and derived five practical guidelines for the successful EA implementation. Simultaneously we propose a future research model for an empirical validation based on current findings.

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.

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.

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.

최근의 정보화환경을 반영한 정보화 관리방법과 도구의 통합 활용에 대한 필요성이 대두되고 있다. 이제는 기존 프로젝트관리 방식만으로는 다원화된 업무, 고객 요구를 충족시키지 못한다. EA, PMO 등 보다 발전된 방법들을 도입하고 활용해야 한다. 그러나 아직도 공공부문 정보화추진에 유용한 개념과 도구들을 통합적으로 활용하지 못하는 것이 현실이다. 공공부분 정보화 정책 환경이 변했지만 아직 현실에 맞게 그러한 사항들이 반영되어 있지 않다. 변화에 맞게 적절한 수단과 방법을 개발하고 지속적으로 발전시키지 못하면 기대한 효과를 거두기도 어렵다. 이제는 CIO 등 정보화를 추진하는 여러 주체가 범정부 EA, IT거버넌스, IT아웃소싱, 각종 지침과 기준 등을 통해 업무생산성을 제고할 수 있는 새로운 접근방법에 대한 제시가 필요하다. 이를 위해 본 연구에서는 EA기반의 PMO제도 적용 활용을 위해 방법론 및 도구의 통합적 활용이 가능한 모델을 제시하고자 한다. 연구방법은 기존 연구결과, 정책, 사업에 대한 문헌연구 및 분석 등을 통해 함의를 도출한다. 결과는 공공부문 정보화 추진 시 생산성 제고를 위한 참조 및 연관되는 유사 IT정책을 추진할 때 방향 정렬(Alignment)에 필요한 시사점 제공과 선행연구로서 의미가 있으리라 기대한다.

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.

This paper presents GDOCF(Government Document Enterprise Architecture Framework) based on the direction of EA(Enterprise Architecture) framework to build GDOCEA. The construction of EA for GDOC offered various types of information technology Platform which advanced the interoperability between Government Information Systems. In addition, it insured the interoperability between the e-Government Initiatives and helped a consistent management for information resource. As a result, MOGAHA could support a policy decision and capital investment plan for information. Also, all the information needed for the operation and management of GDOC has been being referenced, shared and utilized as EA repository. Eventually Pilot EA would be a corner stone to build EA master plan considering all the information systems in MOGAHA.

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.

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.
