Given
Core journeys have test fixtures; supported browser/device matrix and load profile are agreed.
When
Use keyboard, narrow viewport, focus/validation checks and defined concurrent load, including negative access paths.
Then / oracle
Forms/actions are operable and readable; errors are associated with fields and focus is visible. Record latency/error evidence against Balanced targets agreed by DG. No 99.5% uptime or monthly availability is claimed from staging.
Evidence required
Browser/accessibility checklist; measured load report with dataset, concurrency and environment.
Decision dependency (verbatim)
Q09: load, responsiveness, accessibility expectations and acceptance thresholds; not original full-scope targets by default.
