One of the main ways of doing this is through VPATs, or Voluntary Product Accessibility Templates. While there are legal reason why Cayuse uses VPATs, they contain useful information for the UX team as well. If there are products, features, or even components where we see a lot of accessibility issues always happening, we can make sure our Design System documents the correct way to meet accessibility standards from WCAG, as well update our Figma designs, in the library AND in created designs.

The UX team did training on accessibility as well, and would always make sure to reference WCAG documentation. My designs at Cayuse were accessible because of expert knowledge of accessibility, combined with designing with accessibility in mind, as well as a Design System that covers accessibility within it's components and patterns.
