Specifying system requirements (SysReqs) is a critical activity in complex systems development. The SysReqs and emerging architecture are constructed through gradual and iterative transition from the problem domain and operational stakeholder requirements to the conceptual solution domain. They later constitute the basis for functional requirements elaborating, concept formation, technology selection,...
Problem formulation lays at the heart of systems engineering. While an over-constrained solution space may yield no satisficing solution affordably, properly defined solution spaces may enable developing solutions with high levels of affordability. Therefore, effective requirement elicitation from stakeholder needs is key to achieve a proper definition of the problem to be solved. Categorizing requirements...
In the twenty-first century, mission success will require unprecedented interoperability among disparate constituent systems resulting in a System of Systems (SoS). Unlike traditional systems engineering where systems are created based on a set of user needs, a SoS is composed of multiple constituent systems, at various stages within their lifecycles (i.e. new start systems, systems in-development,...
