Are you implementing accessibility in software so as to be compliant with ADA and EAA regulations. How do you implement them, by adapt all your internal developments and checking COTS solutions compliance?

I have only done preliminary work on implementing accessibility in web applications. In planning for our web application development, I've met briefly with our Accessibility Team and gotten this general suggestion:
Use established frameworks such as bootstrap with its pre-defined color schemes as much as possible.
I've also briefly looked at one of the tools we use for running accessibility checks named the ARC Toolkit. It seems pretty easy to use and gives you a report of how accessible a given web page is.

From my employer’s perspective, implementing accessibility in software to comply with the ADA and the EAA is a critical aspect of ensuring inclusivity and legal compliance. Here's how this can be approached:

1. Internal Development Adaptations:

   - Inclusive Design from the Start: Accessibility is embedded into the design process from the beginning. This includes considering diverse user needs, such as those with visual, auditory, cognitive, or motor impairments. Design teams ensure that user interfaces are intuitive, easy to navigate, and compatible with assistive technologies.
   - Use of Accessibility Standards: We follows established standards like the Web Content Accessibility Guidelines (WCAG) 2.1 or later versions to guide the development of accessible web and mobile applications. These standards are integrated into the development lifecycle.
   - Automated and Manual Testing: Regular accessibility audits are conducted using both automated tools and manual testing with assistive technologies such as screen readers. This helps identify and fix accessibility issues before the software is released.
   - Employee Training: Continuous training is provided to developers, designers, and content creators to ensure they are aware of best practices in accessibility and how to implement them effectively.

2. COTS (Commercial Off-the-Shelf) Solutions Compliance:

   - Vendor Assessment: Before acquiring COTS solutions, we assess vendors for their commitment to accessibility. This includes reviewing Voluntary Product Accessibility Templates (VPATs) to ensure that products meet ADA and EAA requirements.
   - Accessibility Clauses in Contracts: Contracts with COTS providers include clauses that require ongoing compliance with accessibility standards. We may also request accessibility improvements if a product does not meet the necessary standards.
   - Continuous Monitoring: Even after implementation, we monitor COTS solutions for accessibility issues, ensuring that any updates or new features maintain or improve accessibility.

3. Cross-Functional Collaboration:

   - Accessibility Team: A dedicated team or accessibility champions within the organization work across departments to ensure accessibility is prioritized in all software and hardware developments.
   - Feedback Loops: User feedback, especially from employees or customers with disabilities, is actively sought and used to improve accessibility features. This ensures that real-world usage informs ongoing compliance efforts.

4. Compliance and Reporting:
   - Regular Audits: We conduct regular internal and external audits to ensure compliance with ADA and EAA regulations.
   - Public Reporting: Transparency in reporting accessibility progress and challenges is maintained, often shared in corporate responsibility reports or other public documents.
