Making Your Service Accessible
Varies on site size
Operability, Usability, Perceivability, Robustness
Choose your accessibility principle:
Operability - Possibly most important, operability in practice means that any user should be able to navigate and use our web application just as well as anyone else regardless of technical competence and any disabilities or disadvantages they might have.Perceivability - which is to say that all of the user interface and content on a website should be perceivable to the user in a way they can understand, even if they have a disability.Understandability - you have to make sure people can understand your content and how the service works.Robustness - make sure your content can be reliably understood by different browsers and assistive technologies
Decide if you want to test one aspect of your service, or the whole thing. Test your service, this might be with actual users (see user testing) or a system you can run your site through which highlights accessibility areas.
We like to use tools such as Color Oracle and NoCoffee which test different aspects of accessibility on your website. Your designers can also implement tools as they are designing such as Color Contrast Analyzer for Sketch
Create a clear report. We like to use traffic light systems to show things that must be changed, might need to change and that are accessibility friendly.
Assign this to the right people to apply these changes and once they are done you can run step two and three again.
