Interest in EA has been Increasing recently, however, with the coming into effect from July 2006 of the 'Information Technology Architecture Act' which requires the public sector to adopt EA. Until now, the study of EA has been focused on concepts and methodologies for the adoption of EA. The fundamental issue, however, the study on the factors affecting the adoption of EA, has rarely been explored. This thesis therefore surveyed which factors have affected the adoption of EA. The analysis found that the adoption of EA was affected by the external environmental characteristics such as rules or regulations and the level of competition in the Industry concerned, and by the organization's information technology level. However, technological aspects such as perceived usefulness or perceived ease of use - traditionally considered as critical factors in adopting information technology - were found to be less influential. These results show that in Korea we still do not regard EA as a method of optimizing the IT resources of a company. In order for EA to be widely adopted, therefore, we should Put primary emphasis on efforts to properly appreciate its technological aspects, such as its technological usefulness or convenience.

The purpose of this paper is to provide an abstracted meta-model for executing Capabilities Portfolio Management (CPM) effectively based on DoDAF2.0. The purpose of developing an architecture is for beneficial use of it. A good set of architectural artifacts facilitates the manipulation and use of them in meeting its usage objectives well. Systems engineering methodologies evolve to accommodate or to deal with enterprise or SoS/FoS level problems. And DoD's Capabilities Portfolio Management (CPM) is a good example which demonstrates enterprise or SoS level problems. However, the complexity of the architecture framework makes it difficult to develop and use the architecture models and their associated artifacts. DoDAF states that it was established to guide the development of architectures and to satisfy the demands of a structured, repeatable method for evaluating alternatives which add value to decisions and management practices. One of the objectives of DoDAF2.0 is to define concepts and models usable in CPM which is one of DoD's six core processes. However, DoDAF and various guidelines state requirements for CPM rather than how to. This paper provides methodology for CPM which includes process and tailored meta-models based on DoDAF Meta Model (DM2).

정부는 공공기관의 자율 책임경영체계를 확립하기 위해 경영관리와 주요사업에 대해 경영실적을 평가하고 있다. 그리고 많은 공공기관이 전략과 IT의 정렬, 정보자원관리, IT 표준화 등을 위해 Enterprise Architecture를 구축 운영하고 있다. 경영평가와 EA 간에는 BSC 기반의 성과관리, PDCA에 기반을 둔 관리 개선 절차 등 많은 유사성이 있다. 본 논문은 두 제도 사이의 유사성과 연관성을 분석하고, 전략관리, 성과관리, 자원관리의 관점에서 경영평가에 EA를 적용하는 방안을 연구한다. 이를 통하여 EA의 활용을 확대하고, 공공기관이 체계적으로 경영평가를 준비하여 성과중심의 경영체계를 운영하는 방안을 제시한다.

본 연구에서는 한국의 EA 추진노력을 준비기, 기반/적용기 및 활용기로 구분하여 정리하였으며, 이후 개별기관 EA와 범정부 EA의 성과 및 시사점과 향후 정책방향에 대한 조언을 제시해보았다. 한국의 EA 추진노력은 개별기관 차원에서는 중복투자 방지, 자원 재사용 등의 성과를 보이고 있으며, 범정부 차원에서도 자원 최적화에 따른 정보화예산 절감의 성과를 보이고 있다. EA 추진현황 및 성과를 알아보고 향후 공공부문의 EA가 지속적으로 발전해 나갈 수 있는 정책방향을 제시한다.

Enterprise Architecture has become a key tool for transforming business process, data, IT and application resources. The "Efficient Adaptation and Management of Information System Act" was established to support the planning and development of the information system in order for the public sector to adopt Information Technology Architecture (EA) into its organization through the act. Until now, the study of EA has been mainly focused on concepts, methodologies and success factors for the implementation of EA. User involvement, which is one of the critical factors in adopting information systems, has been rarely studied in the field of EA research. The purpose of this study is to identify the effects of user characteristics on user involvement in EA implementation. After discussing intrinsic motivators and situational motivators as predictors of user involvement, a research model were developed and tested using survey data. The results showed that among intrinsic motivators, perceived competence had a strong positive effect on user involvement. Some implications were discussed for implementing and utilizing EA for public agencies.

최근 각광 받고 있는 SOA(Service-Oriented Architecture)는 서비스 지향 아키텍처로서, 소프트웨어 개발 및 응용의 새로운 패러다임이라고 할 수 있다. 본 논문에서는 서비스 통합의 중요성이 강조되는 U-City 사업에서 SOA를 기반으로 다양한 서비스들을 효과적으로 관리, 제어할 수 있는 통합 아키텍처를 제시한다. SOA의 주요 특정이라고 할 수 있는 느슨한 결합, 표준 기반, 그리고 분산 컴퓨팅은 U-City 사업의 다양한 서비스를 통합하여 제공하기 위한 필수적인 요소들이다. 본 연구에서는 SOA의 이러한 특징들을 반영하기 위해 통합 플랫폼인 ESB(Enterprise Service Bus)를 이용하였는데, ESB는 상호 이질적인 컴포넌트와 시스템을 연결함으로써 서비스들 간의 통신을 구현하는 SOA의 핵심 모듈이 라고 할 수 있다. 본 논문에서는 U-City 서비스에서 SOA의 필요성과 이를 실제로 구현할 수 있는 가상 시나리오와 구현방법에 대해 논한다. 최종적으로 U-City 통합운영센터를 위한 SOA 기반 통합 아키텍처를 제안한다.

Recently, software distribution method, along with advent of era of Web 2.0, is rapidly evolving from ASP(Application Service Provider) method into SaaS(Soft as a Service) method due to development in concepts and technologies including SOA(Service Oriented Architecture) Web Service, On Demand and Component. Determining factor in market competitiveness of newly emerging SaaS business model will be analyzed by focusing on Group-Wares, POS(Point of Sale) System, CRM(Customer Relationship Management) and ERP(Enterprise Resource Planning), which are the most representative SaaS business models in Korea. It is anticipated that the outcome of analysis of determining factors for market competitiveness for each of the main SaaS Business Models acquired through questionnaire survey can be utilized as important benchmarking material in setting the direction of cultivating SaaS market by the government as well as new entries into SaaS market.

The importance of reliability information management for an effective product quality management has been increased. Reliability management requires many different kinds of human and technical expertise and cost over the various discipline in the organization. However, it is difficult task to set up appropriate and effective life data analysis because of lacking engineers with reliability knowledge, statistical background and of funds in small and medium-sized enterprise. It is needed to develop a low cost implementation architecture of reliability information supporting system for small and medium-sized enterprise under web environment. In this paper, research efforts are presented to solve such problems of small and medium-sized enterprise under web environment.

Intellectual capital is one of the most valuable assets of any enterprise. This empirical investigation examines the causal relationship between intellectual capital and the performance of architecture firms. More than 100 architecture firms across Taiwan have each been assessed for the levels of human capital, structural capital, relational capital, and business performance. The results suggest that the architecture firms exhibit higher levels of relational capital. However, the firms indicate relatively low levels of human capital. Additionally, the results from the correlation analysis suggest that all the four measures (human capital, structural capital, relational capital, and business performance) are highly correlated. The findings from the path analysis also indicate that human capital may influence the performance of architecture firms via structural capital and relational capital.
