The Real Cost of Accessibility
Teams skip accessibility because they think it's expensive. The data says otherwise. Building accessibility into your workflow from day one adds 10-15% overhead. Retrofitting it after launch costs 3-5x the original feature development. Which one sounds more expensive?
The 12-Point Sprint Checklist
Every component we build passes these checks before it leaves development:
1. Color contrast ≥ 4.5:1 for text, 3:1 for UI. 2. All images have meaningful alt text. 3. Form inputs have visible labels. 4. Focus indicators are visible and styled. 5. Tab order follows visual order. 6. Interactive elements have 44px minimum touch targets. 7. Error messages are descriptive and associated with fields. 8. Headings follow sequential hierarchy. 9. Content is readable at 200% zoom. 10. Animations respect prefers-reduced-motion. 11. ARIA labels present on icon-only buttons. 12. Screen reader announces state changes.
What Can Be Automated
Tools like axe-core and Lighthouse catch about 40% of accessibility issues automatically. We run these in CI so every PR is scanned. But the other 60% - keyboard navigation, screen reader flow, cognitive load, real-world assistive technology compatibility - still needs human testing.
Sprint Habits That Work
Design phase: Use Stark or Figma's built-in contrast checker. Annotate focus order on every screen. Design all four states: default, hover, focus, disabled.
Development phase: Start with semantic HTML. Add ARIA only when native semantics are insufficient. Test with keyboard after every component.
QA phase: 10-minute screen reader walkthrough of each new feature. Check tab order. Verify error announcements.
The SEO Bonus
Accessible products rank better. Semantic HTML, proper heading hierarchy, descriptive alt text, and clean structure are exactly what search engines reward. Our accessible projects show 28% better organic performance on average. Accessibility isn't just the right thing to do - it's good business.
