This paper analyzes the limitations and provides alternative options for Korean Military LISI model, which is based on interoperability assessment model, LISI(Level of Information System Interoperability), developed for US defense information systems and reformed to suit the Korean Military environment by ADD. Korean Military's LIST model is applied to all systems(information system, weapon systems, non-weapon systems)' interoperability assessment defined in acquisition regulations by Joint Interoperability Test Center, a subordinate unit of Defense Command and Control Forces and the only assessment agency of defense interoperability. LISI was basically developed as an assessment model for information system's interoperability, but due to it's shortfall in assessing complex systems including information systems, weapon and non-weapon systems required from New environment SOSI(System of Systems Interoperability) has recently been researched and developed. On the other hand, it is inevitable that Korean Military's LISI model face fundamental limitations as an interoperability assessment tool for Defense Information System as well as for weapon and non-weapon systems, since it was benchmarked and reformed from the US LISI model. In order to overcome such limitations, MND and associated agencies are providing improvement methods through studies. This paper will provide LISI capability model's assessment criteria on Application(P), Infrastructure(I), Data(D), restraints of on comparison assessment process of unit systems evaluated and politic alternatives to overcome the restraints.

Recently, the LISI(Level of Information System Interoperability) model has been used to measure level of interoperability in the Ministry of National Defense. This study is proposed for improvement of interoperability level measurement method. The MND has been devoting a lot of effort to ensure defense weapon system interoperability. They enacted related regulations and developed SITES for measuring the level of interoperability. However, the LISI model has problems with using just only DITA and applying MND-AF based on Architecture development. To overcome these problems, this paper proposes how to apply reference model to LISI Model and how to apply LISI Model to MND-AF architecture development.

There are many demands for interoperability between weapon systems as the operational needs for joint and coalition based on network in modern and future warfare have been increasingly needed. In DoD, LISI has been applied throughout information system life cycle from the planning phase to the development phase to assess the level of interoperability. We also developed SITES which is a tool to assess the level of interoperability in information systems. But we should extend the assessment model from the previous information systems to the weapon systems to assess the level of interoperability including weapon systems as well as information systems. In this paper, we proposed the assessment model of interoperability, implemented the E-SITE based on the proposed model, applied 12 weapon systems and analyzed the experimental result.

In Korean military measuring systems interoperability is based on LISI (Level of Information System Interoperability) model at the requirement generation and acquisition process. However, LISI model cannot be used for interoperability measurement of system of systems (SoS) because LISI model is focused on interoperability measurement of a given system or system pair. Also, LISI model cannot provide quantitative information for interoperability decision because of qualitative rather than quantitative approach. This paper proposes a quantitative interoperability measurement methodology of SoS. At the proposed methodology, mission threads and supporting systems are identified using architecture approach, and Interoperability of SoS is measured with systems multiplicity and resemblance coefficient. Finally, a case study is presented to show the usefulness of the methodology.

The Systems Interoperability Test and Evaluation System(SITES) is an T&E support tool for both information system and weapon system. The SITES was developed by reference to the Level of Information Systems Interoperability(LISI) in US. We use the tool via MND Broad convergence Network(BCN) in order to assess information system's interoperability. Nowadays, there are many ongoing researches on expanding assessment capability into weapon systems. As part of those research topics, this paper analyze the characteristics of tactical data-link messages which is the way to exchange the information among the weapon systems, and reflect that characteristics in interoperability level assessment.

The level of information system interoperability of DPMS(Defense Procurement Management System) and DCMIS(defense weapon system configuration management information system) was measured. Two information systems interoperability is analyzed using measured results and the level of interoperability were estimated. The results was directed to the future improvement project of information system.

According as the requirement of custom for the enterprise or government organization gets to be various, the enterprise or government organization has been quickly changing to cope with the situation. Recently, by considering a domestic situation which is intending the e-government, the service for the people to apply the information technology of a local autonomous entity is very much need. However, it is actual circumstances that share and application of information is not smoothly realized in the state that government organization introduces the relevant system. To solve this problem, this paper performs a study what the level of interoperability has relation to organizational Performance using interoperability with information system.

본 연구에서는 정보기술 표준의 활용과 그에 따른 정보시스템의 상호운용성 수준과의 관계를 알아봄으로써 정보기술 아키텍처(ITA)에서 강조하고 있는 정보기술 표준의 활용 수준이 높으면 정보시스템의 상호운용성 수준도 높을 것인지를 실증적으로 알아보고자 하였다. 또한 정보기술 표준의 활용에 대한 측정을 위해 정보기술 아키텍처의 3가지 요소(EA, TRM, S/P) 중 하나인 기술참조모델(한국전산원의 TRM)의 표준서비스 분류를 선택하였고, 정보시스템의 상호운용성 수준을 측정하기 위해서는 정보시스템 상호운용성 수준(LISI : Levels of Information System Interoperability) 모델에 따름으로써 정보기술 아키텍처적 관점에서 접근하였다. 설문지를 통한 실증연구 결과, 다양한 표준서비스 중에서 보안서비스, 플랫폼서비스 및 데이터교환서비스 표준만이 실제 정보시스템 상호운용성에 영향을 미치는 것으로 나타났다.

Korea has been ranked at the top consecutively in UN e-Government Survey. This fact reflects consistent efforts by public institutes in Korea. However, there were some duplicate efforts and inefficiency in the investment into IS(information systems). In other words, management and decision making on e-government have yet to improved. Accordingly, governmental institutes have long been promoting policies for EA in order to carry out and manage effectively IT projects including the e-Government projects. EA is being regarded as a means to facilitate IT Governance for systematic management of IT projects, A major objective is to firmly establish the decision making process for IS investment through EA, since the each institute is a large organization with so complicated and specialized demand for IS. As a result, systematic decision making is becoming quite difficult. Thus, this study attempts to identify different types of IT investment decision making and to figure out the relationship between the decision types and the organizational performance of public institutes where EA was implemented.
