Performance and Accessibility
Performance and accessibility are release qualities, not optional polish. Define budgets against representative workflows and test the exact release artifact.
Performance Review
Measure response latency, query volume, repeated work, memory, asset weight, and browser responsiveness. Investigate regressions against the route's established baseline instead of assuming one universal threshold fits every workflow.
Accessibility Review
Target WCAG 2.2 AA for critical experiences. Automated checks should cover landmarks, headings, labels, accessible names, focus visibility, and common contrast failures. Manual checks should include keyboard-only navigation, zoom, screen-reader announcements, dialogs, menus, errors, and focus return.
Automated tests catch common regressions; they do not replace testing a new workflow with assistive technology.
