Abstract: This paper discusses a detailed method for accomplishing situational awareness (SA) on a computer. Following an earlier paper on the topic, the specific case of the Iraq conflict from 2003–2008 is used as an example context. To validate this computational SA, a rudimentary system dynamics model is used to generate fictitious extreme-case data that bounds the actual data. For reasons to be explained in this paper, the computational SA is then built from the extreme-case data and then tested on the actual data. From this approach, it is shown that the implementation of the computing algorithms used here delivered results consistent with observed behaviour in the theatre. Consequently, this study contributes an alternative way in which computer-based calculation can aid large organizations in making decisions on complex matters of international policy.
