Non-functional requirements are formalized as SEI-style quality attribute scenarios attached to specific use cases, defining a stimulus, a measurable response, and an acceptance measure to ensure verifiability and traceability.

SEI-style quality attribute scenarios are structured formats that define a stimulus, a response, and a measure. They capture quality attributes like performance, security, and scalability to make non-functional requirements testable and verifiable across use cases.

You ensure traceability for quality attributes by attaching QA scenarios to specific use case IDs or the entire system, linking non-functional requirements directly to architecture, design, and testing decisions through structured QA-IDs.

Yes, you can define system-wide quality attributes. The approach formalizes non-functional requirements for the entire system or attaches them to specific use cases, covering performance, security, availability, compliance, and observability.

The best way to make non-functional requirements verifiable is to define them as quality attribute scenarios with explicit stimuli, responses, and measures. This structured output ensures they are testable and traceable to specific use cases.

You need use cases defined to attach specific QA scenarios with traceability. However, you can also capture system-wide quality attributes independently if your use cases are not yet fully defined.
