Courses/Introduction to Design Systems/Accessibility First: WCAG & Inclusive Foundations/
Exercise #1

Accessibility as a Systemic Multiplier

In traditional product teams, accessibility (a11y) is often treated as an afterthought—an eleventh-hour audit before launch that results in rushed, fragile fixes. Teams test screens individually and repeatedly miss basic errors like missing labels or unreadable contrast.

A design system transforms accessibility into a systemic multiplier:

  • When an accessibility engineer and designer ensure that a core Button or ModalDialog component is fully WCAG-compliant (proper contrast, focus management, ARIA roles, and screen reader announcements), every product squad inheriting that component is compliant automatically.
  • Baking accessibility into the foundation prevents hundreds of repetitive regressions across web, iOS, and Android applications.
