The toolset for executable models development that can be customized to different systems will be useful within DoD organizations in which software intensive product lines are common. For example, the Unmanned Aerial Vehicles (UAV) Domain is enjoying a period of significant expansion. UAVs have progressed from target drones to reusable weapon systems. Their software systems have become complex and extremely diversified. Domain specific executable SysML models could reduce development risks by enabling many alternative operational concepts and designs to be evaluated before significant effort is expended developing poor designs. In the commercial arena, adopting the same type of approach for software intensive system can be used in a broad range of areas, such as airplane, power plant SCADA systems, and vertical business applications such as Human Resources applications. This type of technology can be adapted to these different domains and provide benefits similar to those provided to NASA.
