The U.S. Department of Defense (DoD) System Engineering Guide for System-of-Systems Engineering (Version 1, August 2008) defines four types of systems of systems, directed, acknowledged, collaborative, and virtual.* We focus our research efforts on the first three of those types, directed, acknowledged, and collaborative.

In applying this research to real-world situations, we are seeking collaborations with organizations that looking for system-of-systems solutions through investigations such as

Our research thrusts rest on a set of system-of-systems practices—a conceptual framework, methods, processes, and tools for supporting multiple dimensions of distributed collaboration. Among the practices we are exploring are the following:

  • Distributed, loosely coupled collaboration promotes system-of-systems agility.
  • Independent and continuous evolution means that system-of-systems behavior cannot be completely predicted.
  • Influence is more important than control in getting collaboration between system-of-systems stakeholders.

Based on that set of principles (which we continue to enhance), we view the needs of those types from the viewpoints of governance, engineering, and acquisition.

  • For system-of-systems governance and acquisition, we are looking at the influence and reward structures in system-of-systems collaborations, ensuring relevant stakeholder participation in decision-making, guidance on system-of-systems acquisition and evolution.
  • For system-of-systems engineering, we are working toward the development life-cycle practices by leveraging research and best practices from SOA and other implementation approaches.
