  • Proliferation of IT applications and developments lead to many useful yet diverse information systems being used in an organization. Users of information system have been satisfied with useful functions and prompt outputs, however they have become realized the problem of incompatibility of diverse systems and asked for more compatible systems in which more data and software can be shared among users. Information technology architecture (ITA) is suggested as one way of avoiding such problem by many researchers. This paper ananlyzes and introduces the ITA approach used primarily in US governments and in many other organizations. In Korea, many researchers view ITA as a technical concept that deal with interperability and standards. However, ITA is more managerial oriented concept than technical, because it allows us to achieve managerial objective, for example alignment of IT to strategic objectives, with ease and more confidence. This paper proposes the necessity of ITA in IT management and clarifies the relationships of managerial focus with technical focus of ITA.

  • As the innovation of Information technology in the Public sector is in progress, the "Efficient adaptation and management of information system Act" (passed the National Assembly in December 30, 2005) was established to support the information system planning and development which are systematic and integrated in the enterprise view point. The public sector should adopt Information Technology Architecture into it's organization by the act. This paper reports on the issues, solutions and CSFs (Critical Success Factors) considering the adoption of ITA through the implementation for the case of the Korea Post. To adopt ITA program to the Public sector successfully, Korea Government should set the clear goals for IT A, set the standards for IT A project pricing, and collaborate with the system integration industry to make successful IT A program cases. The case study of Korea Post of MIC will be useful in developing and managing ITA programs for all agencies and organizations considering adoption of ITA.

  • This study is an approach to solve the problem concerning informatization and its investment of the existing information system. In this regard, IT Architecture is becoming a prominent figure, and great efforts are being taken to establishment of related infrastructure environment such as the 1st and 2nd pilot programs, ITA related law's legislation, and development of a reference model and its guidance. Especially, with 'the bill on the introduction and management of the information system' passing the National Assembly, all sorts of environment involved for the introduction of IT Architecture in the future such as establishment of the political foundation for IT Architecture introduction of public organizations, and integrated IT Architecture management system(G-ITAMS) is establishing the constituency. Therefore, this study aims to grasp accurately the actual condition concerning the introduction and utilization of IT Architecture at domestic public organizations, which was followed by investigation to present the right direction in the future, and the findings were discussed in the main body as follows:

  • The Law of effective building and operation for the information systems took effect at Dec. 2005. Every government and public agency have to build own enterprise architecture(EA), sometimes it's called the Information Technology Architecture(ITA), by this law. The Ministry of National Defense(MND) built the enterprise architecture(EA) during 2006. 12$\sim$2007. 11 by this law too. We knew the specific characters of the public sector thru the EA project. The public sector is less active than commercial sector and most members of the public sector are just looking on the project as a spectator. So the most of key for the success of EA is how to catch the Sponsorship and Participation of members. In this paper we propose the effective building methodology for the Enterprise Architecture of public agency applying the MND-EA. The other governments and public agencies can build own the EA easily by the proposed methodology.

  • As $\ulcorner$Law about efficient introduction and operation etc. of information system$\lrcorner$ that is called ITA law is enforced by July 1, 2006, Information Technology Architecture introduction is beginning in earnest in public institution. Because information present condition grasping, policy-making, and efficiency of information investment decision are increased in country dimension through Information Technology Architecture. This paper introduces Information Technology Architecture's concept and domestic Information Technology Architecture construction's present condition, NTIS Information Technology Architecture construction example, and describes about 'Information Technology Architecture Framework' that is the point of 'Information Technology Architecture base thesis' for Information Technology Architecture induction, practical use and management among them.

  • ITA (Information Technology Architecture) satisfies the requirements of information system, supports the information used in the institution's business to guarantee the interoperability and security, and analyzes the components of information system. ITA consists of EA (Enterprise Architecture), TRM (Technical Reference Manual) and SP (Standard Profile). The SP, one of the major components of ITA, is a set of information technology standards. In this paper, to construct and utilize the ITA, we mention the applications of information technology about the SP system implementation based on the TRM. The SP management system implemented in this paper is the first trial in Korea, and designs the software with object oriented programming languages such as JSP and Java. Moreover the basic and detailed specification based on the UML notation, system design using the component and system design pattern consisting of software architectures enhance the software reusability. And the constructed system in this paper shows less maintenance cost by using the public softwares such as Linux system, Korean DBMS, Apache and Tomcat, etc. Finally, the system includes the SP reference system which is used in the other institutions and cannot be found in other institutions. Also it includes the additional diverse service modules which support the subsequent processing for the establishment and revision of standards via internet.

  • 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.

  • Information Technology(IT) was introduced to the business as a means of improving operational efficiency. Nowadays, IT has become an essential component of an organization's survival. Almost no operations of an organization can be performed without IT. The benefits of using IT in organizations can not be underestimated. Some organizations have flourished because of the competitive advantages derived from the IT systems they have developed. Most IT systems, however, have been extended, changed and integrated with ad-hoc and makeshift solutions without thinking long-range view. It results in high maintenance cost and uncontrolled system for managing information resources. Especially, public institutions under the Project-Based System (PBS) have some problems in keeping a good management systems for information resource, because they are usually operated for a set period. Therefore, we propose the framework how to efficiently manage the IT assets and resources based on the Information Technology Architecture (ITA) that is introduced for the overall optimization of IT investment, change management and inter-operability.

  • 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.
