Abstract: In this paper, we describe the FINC methodology for analysing C4ISR and NCW architectures. We utilise the "Black Hawk Down" incident in Mogadishu as a case study, in order to demonstrate how the FINC Intelligence Coefficient metric is calculated. We show how the FINC methodology can be used to evaluate possible improvements to the C4ISR architecture used in Mogadishu, and to NCW architectures more generally.
