This study is designed to define the competencies of EA experts. We investigated domestic and oversea curriculums and finally suggested basic and common competencies of EA experts. Especially, various EA stakeholder can commonly refer and use our competencies. Therefore those can be the foundation of continuous EA competencies development model. We define 4 EA core competencies such as common, development, analysis, management and provide definition of competencies. And we also classify the competencies importance of 3 career paths (Architect, Enterprise Architect, Chief Architect). The results of this research can help EA experts and IT personnel to understand EA and to enhance their competencies by providing standard competencies of teaching course and curriculum.

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.

Many Countries are recently focued on building capability based military and operating for the defense budget efficiency and operational effectiveness. The EA not only defines enterprise scope but also identifies relation among them, manage change and complexity. Accordingly, this research aims to build architecture framework which can achieve alignment, integration and interoperability by developing it with output. Through this, architecture framework can be changed into force development and operation. And it can be used for construction of effective force and operation for NCO by applying mathematical model and method of force priority development based on developed capabilities-based architecture framework.

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.

EA (Enterprise Architecture) is an SI (System Integration) approach, i.e., a comprehensive plan for SI, which shows the elements of SI and the relationships among them. Since EA can be utilized in every stages of SI, the more large-scaled and complicated SI projects are, the more important EA is. Although many central government agencies and wide local governments implemented EA, the current level of EA utilization is still low. One of the reasons is the low level of EA updating. Some reasons of the low level of EA updating are the low frequency of EA updating, and the shortage of workers, as well. In order to improve the frequency of EA updating and alleviate the workloads of SI officers, MLTM (Ministry of land, transport, and maritime affairs) standardized the processes and documents for SI projects, and implemented PMS (Project Management System) that can support the unifying management of SI projects and be connected with EA system. We expect that EA information are updated efficiently, the level of EA utilization is boosted, and the qualities of SI products are improved, by the implementation of the PMS connected with EA system.

Today, a corporate and the government is making significant investments in informatization in order to enhance competitiveness however, question on the outcome of information-oriented investment has continuously been posed and in order to resolve such problems, the technique of Enterprise Architecture (EA) Despite such fact, in the case of the central administrative institute, even if the EA maturity standard has continuously improved through continuous investment when compared to the past without deviation between institutes, the establishment of EA and the work utilization of EA compared to the management competence still is analyzed to be relatively weak. This study completed the preliminary feasibility study in 2012 for Korea Customs Service which has been appointed as the representative institute that best utilizes EA in the field of information operation and evaluation field in the 2010 EA Maturity Evaluation and it can become a case study that can contribute to more continuous development and improvement of other public institute EA by introducing the performance of EA-based 4th Korean National Customs Information Network which has entered into total reconstruction in 2013 and by identifying the implications of EA performance arising from such.

The rapid development of IT and the large-scale investment of IT motivate the public agencies to find the ways of effective IT management. Even though the public agencies adopt Enterprise Architecture (EA) as the new alternative for effective IT management, EA practices are still insufficient in the area of utilization and management after the adoption. Therefore, this research aims to identify the influencing factors for improving EA maturity level in terms of the long-term business activities such as establishment, management and utilization. Also, this research empirically identifies the influencing factors on the adoption and operation of EA in the public agencies, and clarifies how such factors impact on EA maturity level.

Since EA includes huge information of a company, it takes long time and high cost for company's employees to search for what they need. We try to make the foundation to solve this problem by using ontology technology based on semantic web. In this paper, we try to verify efficiency of EA ontology by developing ontology for Business Enterprise Architecture(BEA). The purpose of this paper is to develop BEA ontology to provide new information by reasoner and to discover new relations between matadata by using extracted information and data. The EA ontology we developed will provide the new way of access and use for companies. The experience of ontology development will help EA ontology development in various domains. In the future, the development of other EAs which has more information resources will help to solve problems for interoperability between different EAs.

This paper explores how the provided information from Enterprise Architecture (EA) affects the activities to for performing IT projects. The IT projects analyzed in this paper are projects to for developing and maintaining Korea Customs' UNI-PASS. This research was conducted based on surveys to demonstrate the effects of the information from EA on activities for IT projects. Information from EA is categorized into propriety, sufficiency and consistency. Activities for IT projects are defined as management, participation, communication, requirement management and human resource. Correlational analysis is used to measure the effects of the inf ormation on the defined activities. The analysis, which verifies the provided information by EA, does not have meaningful correlation with project management nor human resource. For public officials in charge, Sufficiency of the information produces a positive effect on decision making. For operation company, consistency of the information encourages utilization of the resources required for the project. This research suggests that strategies for performing IT projects with EA information that can support the verification of characteristic environments of each project and performance of vital activities required by the participants' roles will ensure the success of government IT projects.
