System-of-Systems Engineering (SoSE)

System-of-Systems Engineering (SoSE) is a set of developing processes and methods for designing and implementing solutions to System-of-Systems problems. SoSE is relatively new term being used in Department of Defense applications, but is increasingly being applied to non-military/security related problems (e.g., transportation, healthcare, Internet, search and rescue, space exploration). SoSE is more than systems engineering of complex systems because design for System-of-Systems problems is performed under some level of uncertainty in the requirements and the constituent systems, and it involves considerations in multiple levels and domains. Whereas SE focuses on building the system right, SoSE focuses on choosing the right system(s) to satisfy the requirements.
