Lista de verificación para diseñadores, ingenieros, gestores de proyectos, aseguradores de calidad y creadores de contenido

Muy interesante el recurso The Checklist, que plantea diferentes listas de verificación según el perfil del implicado en un desarrollo web:

Designers
Make sure there is enough contrast between text and its background color
Don't indicate important information using color alone
Pair values of colors together (not only hues) to increase contrast
Don't rely on sensory characteristics as the sole indicator for understanding and operating content
Design focus states to help users navigate and understand where they are
Help users understand inputs, and help them avoid and correct mistakes
Write good alt text for your images
If an experience cannot be made accessible, create another route for users to get that information
Be as consistent and clear as possible in layout and copy

Engineers
Use the correct HTML element for your content
Support keyboard navigation
Understand and use HTML landmarks
Write good alt text for your images
Design focus states to help users navigate and understand where they are
Help users understand inputs, and help them avoid and correct mistakes
Use ARIA attributes when applicable
Give users a way to skip top level navigation to access main content
Make links descriptive
Avoid text in pseudo elements
Make SVGs accessible to assistive technology
Hide decorative elements from screen readers
Create alternate routes for users to access information
Links should be visually identifiable and have clear :focus and :active states

Project Managers
Familiarize yourself with the work associated with making content accessible
Build in time for accessibility during project planning and sprint planning
When sharing good work done by your team, praise efforts to increase accessibility
The tools and products that you create should make accessibility easier to achieve
Be an advocate for accessibility

Quality Assurance
Run through each page with the WAVE Chrome Extension
Users should be able to navigate through content using their keyboard
Users should be able to navigate content using a screen reader
The general architecture and hierarchy of the content should make sense
Charts and images should all have alt-text so that users with screen readers or users on a slow connection will still be able to understand the images
Decorative images should not be visible to screen readers

Editorial
Write good alt text for your images
Editorial Engineers: think about how custom experiences can be made accessible
Be as consistent and clear as possible
Links should be descriptive
Important information should not be conveyed through images, color, or sensory characteristics alone
