Abstract:

This report presents an analysis of the state of the practice in system-of-systems SoS development. SoS architectures, or blueprints for integrating multiple systems based on common software platforms, have been successful in many commercial environments. The report discusses technical issues related to SoS common platform development and adoption in the Department of Defense DoD and the nontechnical constraints that must be satisfied. The analysis is based on information captured from 12 interviews of leading SoS developers in the DoD and industry, applying a SoS definition from the literature to identify gaps between the current state and the desired end state. The results of the study show that while commercial and DoD developers follow different approaches, all organizations report nontechnical constraints as more challenging than technical issues. For the DoD, these include leadership changes, shifting political priorities, and difficulty in replacing suppliers. The report recommends further study of SoS planning and agile approaches that better support incremental development bridging the gap from SoS to system concerns so that system designers understand SoS concerns and can focus on their products in the context of the SoS and documenting the platform at all software levels, including architecture views and component integration strategies.
