Abstract. The United States Navy's focus on Information Dominance as a warfare enabler requires an integrated and coordinated System of Systems (SoS) for mission success. The Space and Naval Warfare Systems Command (SPAWAR) has been designated the Information Technology Technical Authority (IT TA) to address the challenges posed by this unprecedented interoperability among Navy systems. To address these engineering and planning challenges, SPAWAR has adopted a System of Systems Engineering and Integration (SoSE&I) methodology. SoSE&I is the planning, analyzing, and integrating constituent systems into an SoS capability greater than the sum of those systems. This paper defines the SoSE&I "Vee" process model, and discusses how it is used to engineer the SoS throughout its life-cycle, and how it can be used by decision-makers to increase systems integration and interoperability to directly impact the operational effectiveness of the Navy's networks and weapons.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
