The best way to do this is to nominate a team member to take the lead, to be your internal accessibility advocate. When undertaking internal design critiques, add a section for an accessibility review. These conversations help to up-skill the whole team on conformance guidelines. You can also decorate the office with educational snippets; the GDS team here at Dept UK have produced some great posters about accessibility that you can download for free.
Secondly, we need to create empathy within our UXD teams. In design, it can be hard for people to grasp the importance of accessibility if they have no personal experience, whether directly or indirectly. Invite people with disabilities into your design process so they can educate the team on the challenges they face with your creations. This real world experience will stick in the team’s mind much longer than statistics ever will, and its impact will be much more profound.
