Executive SummaryThe Department of Defense (DoD) has placed a growing emphasis on the pursuit of agile capabilities via net-centric operations. The breadth of technological advancements in communication and sensing has generated exciting opportunities for battlefield systems to exploit collaboration to multiple effects. In this setting, systems able to interoperate along several dimensions increase the efficiency of the overall system-of-systems (SoS) manifold. However, the manner in which these system-of-systems are acquired (designed, developed, tested and fielded) hasn't completely kept pace with the shift in operational doctrine. In our current project, we have attempted to unravel the layers of complexities in an SoS acquisition program, outline an acquisition strategy better suited for such programs and develop an exploratory analysis tool to provide insights into the acquisition process.The research efforts during the report period have focused on the development of two types of tools to investigate the impact of development dependencies on the successful acquisition of SoS: 1) a computational exploratory model and 2) an analytical approach.The conceptual model for acquisition strategy proposed in our project is based on the 16 technical management and technical system-engineering processes outlines in the Defense Acquisition Guidebook (DAG), often referred to as the 5000-series guide. Our conceptual model for acquisition is centered on the revised processes of the 2007 System-of-Systems System Engineering (SoS-SE). Simulation of the development process, however, is not always feasible due to the large amount of information required to perform a simulation. The analytical approach seeks to augment the computational approach by developing a method that enables the comparison of networks of systems that are connected to each by developmental interdependencies by exposing and quantifying the cascading effects of development risk. The goal is to allow acquisition professionals to develop intuition for procuring and deploying system-of-systems.Applications of the modeling tool and the analytical network analysis method to different SoS topologies enables the comparison ...
