Abstract: To determine whether or not a system has sufficient capability to complete a mission following a damaging event is part of the evolution of combat. This problem cannot be easily answered using traditional methods and metrics within the live-fire analysis community. As traditional analysis efforts have focused on qualitative metrics, a need for a quantitative methodology and metric was identified. To fill this need, the System Capabilities Analytic Process (SCAP) was developed. SCAP quantitatively and logically links the functional states of a system's components to the capabilities of the system, which are expressed in terms familiar to the military user of the system. The primary product generated by SCAP is the functional skeleton (FS), which is a map between a system's components and its capabilities. The FS includes both the material components of the system as well as the personnel operating the system. It will be shown how the FS can be used to link the capabilities between individual systems into system array capabilities, and also how the FS can be used to determine the performance of systems in an interacting system-of-systems. Methods for representing the FS mathematically are also discussed.
