System-of-Systems Software Architecture Evaluation

White Paper
System-of-Systems Software Architecture Evaluation

Software Engineering Institute


Software-intensive systems often suffer severe integration and operational/ behavioral problems due to a lack of consistency between the system and software architectures in addressing system quality attributes. These problems often result in rearchitecting and redesigning efforts and operational failures, which significantly affect system cost, schedule, and mission effectiveness. These problems are further exacerbated in a system of systems (SoS) context.

In conjunction with the Mission Thread Workshop (MTW), the SoS Architecture Evaluation Method provides an initial identification of SoS architectural risks and quality attribute inconsistencies across the constituent systems.
