Abstract
This study aims to identify the effects of the technological and individual characteristics of army tactical command information system (ATCIS) on situation awareness and decision making, under the concept of network-centric modern warfare. On the basis of adaptive structuration theory and situation awareness theory, we consider the technological characteristics of the system as real time, convergence, and information visualization effect. System experience and IT capability are used as the variables for individual characteristics. We hypothesize that these variables affect users’situation awareness which leads to their decision making. A field survey is administered to the Republic of Korea (ROK) Army officers who have experienced using the system for more than six months.BR Survey results show that excluding real time, convergence and information visualization effect influence users’situation awareness. Users’ system experience and IT capability also increase situation awareness. The higher the degree of users’ situation awareness, the better their decision making. Theoretically, this study implies thatthe effects of the technological and individual characteristics of ATCIS on situation awareness must be investigated. Practically, our study guides and suggests development plans for the ATCIS to the ROK Army.
