A strong mapping output is a requirement matrix, not a slide. For each product or service surface, record the Annex I outcome, the EN 301 549 clause or clause group, any linked WCAG criterion, the engineering acceptance criterion, the test method, and the owner. This turns the legal text into something teams can build and QA can verify.
The AccessibleEU guidance in the grounding pack also points to practical clause examples for text alternatives, heading structure, keyboard accessibility, captions, audio description, voice alternatives, real time text, contrast, flash limits, and clear instructions. Those are good anchors for building your initial clause library.
