Abstract:

Accessibility is not something to be left to specialists hired to clean up our mess at the end. It should be a priority of the entire development team from the beginning. Yes, companies should definitely have accessibility people on-board, but they should act as much as educators and coaches as designers. Everyone on the development team must be aware of and responsive to the full spectrum of identified users if your product is to sell to the widest possible audience. That’s the only way to achieve inclusive design.
