Definitions alone are not enough
This glossary is meant to help policy, QA, procurement, and delivery teams use the same terms in the same way.
Accessibility Glossary and Definitions
Long-form definitions with implementation context for accessibility, procurement, governance, quality, and SEO terminology.
Why this glossary is intentionally operational
Useful for onboarding and review
Use these pages to align internal language before training, vendor review, pilot planning, or incident-response discussions.
Built to reduce ambiguity
Each term is expanded with implementation context so the glossary supports real decisions instead of acting as a static dictionary.
