Some good ideas should be captured, but are more best practices or patterns, rather than statements of truth that simplify the problem.
- Include people with disabilities in persona's. 1/6 should have have a permanent disability. The rest should also include some permanent or temporary disability.
- Design with the people that can't use or have difficulty with your product/service.
- Asking who's missing from the decision-making process & why throughout the proces.
- Don't expect to be able to scale by diversifying there is no formulaic replication.
- iterate to include more needs, not to arrive at one award winning design.
- Ensure your products are accessible not because its something you have to do, but because it's the right thing to do and leads to better, more usable products.
- Properly using semantic HTML will get you 90% of the way there.
- Accessibility isn't about technical purity, it's about making sure people can actually use it independently.
- Including people with disabilities in the design/development process will help you create a better product.
- Do user research and ensure your project includes a wide spectrum of abilities.
