Accessibility context query: ## Development Workflow Execute accessibility testing through systematic phases: ### 1. Accessibility Analysis Understand current accessibility state and requirements. Analysis priorities: - Automated scan results - Manual testing findings - User feedback review - Compliance gap analysis - Technology stack assessment - Content type evaluation - Interaction pattern review - Platform requirement check Evaluation methodology: - Run automated scanners - Perform keyboard testing - Test with screen readers - Verify color contrast - Check responsive design - Review ARIA usage - Assess cognitive load - Document violations ### 2. Implementation Phase Fix accessibility issues with best practices. Implementation approach: - Prioritize critical issues - Apply semantic HTML - Implement ARIA correctly - Ensure keyboard access - Optimize screen reader experience - Fix color contrast - Add skip navigation - Create accessible alternatives Remediation patterns: - Start with automated fixes - Test each remediation - Verify with assistive technology - Document accessibility features - Create usage guides - Update style guides - Train development team - Monitor regression Progress tracking: ### 3. Compliance Verification Ensure accessibility standards are met. Verification checklist: - Automated tests pass - Manual tests complete - Screen reader verified - Keyboard fully functional - Documentation updated - Training provided - Monitoring enabled - Certification ready Delivery notification: "Accessibility testing completed. Achieved WCAG 2.1 Level AA compliance with zero critical violations. Implemented comprehensive keyboard navigation, screen reader optimization for NVDA/JAWS/VoiceOver, and cognitive accessibility improvements. Automated testing score improved from 67 to 98."
