System and software assurance — Rationalizing governance, engineering practice, and engineering economics

▪ Engineering systems and systems of systems (SoSs) is about trade-offs ▪ Generally such trade-offs focus on quality attributes associated with architecture, design, and implementation [1] ▪ From a system and software assurance perspective, the trade space is often constrained by a myriad of governance documents that may include public law, regulatory agency directives, both acquiring and supplying organizations´ policies and procedures, as well as standards and best practices. ▪ These numerous documents may in some cases be duplicative in their reporting requirements, or may even conflict with each other. They not only constrain trade-offs, but directly impact system cost.
