What makes Systems of Systems (SoS)Different?• Compared to a System, an SoS might:– Be larger in scope– Have more complex integration– Usually be subject to higher degree of uncertainty and risk– Evolve more continuously with elements of differing lifecycles– Lack a single management/acquisition entity and have abroader range of stakeholders– Have elements which are not designed to fit the whole, andwhich are integrated post-design and deployment– Exhibit emergent behaviors– Have more ambiguous requirements and fuzzy boundaries– Have continuous SE which is never finishedSystem-of-Systems Engineering is an emerging discipline in the aerospace communityand new methods and techniques are required to address SoS challenges, but theseshould be based on proven Systems Engineering methodsDeveloping Methods and Techniques for System of Systems EngineeringDr. Dimitri Mavris, dimitri.mavris@ae.gatech.eduSources: INCOSE SE Handbook v3, "Architecting Principles for Systems-of-Systems“ by Mark W. Maier, DoD SE Guide for SoS10
What is SoSE?• System of Systems (SoS) Engineering is an emerginginterdisciplinary approach focusing on the effort required totransform capabilities into SoS solutions and shape therequirements for systems. SoS Engineering ensures that:– Individually developed, managed, and operated systems function asautonomous constituents of one or more SoS and provide appropriatefunctional capabilities to each of those SoS– Political, financial, legal, technical, social, operational, andorganizational factors, including the stakeholders’ perspectives andrelationships, are considered in SoS development, management, andoperations– A SoS can accommodate changes to its conceptual, functional,physical, and temporal boundaries without negative impacts on itsmanagement and operations– A SoS collective behavior, and its dynamic interactions with itsenvironment to adapt and respond, enables the SoS to meet orexceed the required capability.Source: System of Systems Engineering Center of Excellence, Sponsored by the Office of the Under Secretary of Defense for Acquisition,Technology, & Logistics, Defense Systems, Systems and Mission Integration, Joint Force Integration (USD-AT&L)Developing Methods and Techniques for System of Systems EngineeringDr. Dimitri Mavris, dimitri.mavris@ae.gatech.edu11
