The Republic of Korea’s Ministry of National Defense (ROK-MND) has developed various defense information systems, and most of the projects for the development of such information systems are now in their completion or maintenance stage. Because information system (IS) use is a precondition to get the benefit and it can show what IS should be improved, measuring IS use is important. In this study, we benchmarked ISO/IEC 25010 and a guideline of Korean government for operational performance of information systems. We proposed the framework that can measure the degree of IS use with three perspectives such as task support, relevant information provision, and user convenience from the viewpoint of users, and conducted an evaluation of defense information systems with it. Moreover, we classified the defense information systems into four groups by two dimensions such as the status of use and the frequency of maintenance demand, and then made suggestions for better management of IS in each classification.
