Are the non functional requirements same as the systemic qualities. By definition systemic qualities are properties of a system that establish the quality of service that the system can deliver. I'm assuming this would be part of SCEA 5. Thank you.

Non-functional requirements and systemic qualities are not the same thing but do overlap. Non-functional requirements include performance, scalability, reliability, availability, extensibility, maintainability, managability and security whereas systemic qualities are only related to the performance of the application - most particularly scalability but also reliability and availability. Any decent book on architecture can explain non-functional requirements for you in more detail.

What 'System Qualities' are in Systems Engineering parlance, I guess the same is called 'Non-functional Requirements' in Software Systems Architecture parlance (or even SCEA parlance :-))

In fact, it might even appear that SQ is a superset of NFR. Concepts like Usability or Recoverability is not listed under NFR.

I guess Gitzel, Korthausa, Schadera in Using established Web Engineering knowledge in model-driven approaches in Science of Computer Programming 66(2), 105-124 could provide some additional help.
