3. Integrating the tool into their development workflow to ensure ongoing compliance.

Key Considerations for Tool Selection

1. Ease of Use: The tool had to be user-friendly for designers, developers, and QA teams.
2. Comprehensiveness: It needed to detect diverse accessibility issues, such as contrast ratios, keyboard navigation, and ARIA roles.
3. Integration Capabilities: Compatibility with existing CI/CD pipelines for continuous testing.
4. Cost: Budget constraints required an affordable or open-source solution.

Evaluation Process

1. Tool Testing:
   • Conducted pilot tests with Axe, Wave, Lighthouse, and Pa11y on sample pages.
   • Evaluated each tool’s ability to detect issues, generate reports, and provide actionable fixes.
2. Stakeholder Feedback:
   • Involved designers, developers, and accessibility experts to assess usability and effectiveness.
   • Gathered feedback on how well each tool aligned with their workflows.
3. Scoring Criteria:
