Last night I spoke for about 25 minutes at the Accessibility Toronto meet-up. Joseph McLarty led with an overview of accessibility as a concept, touching on disabilities and simple testing techniques (see his slides at SlideShare). Then I ran through the following slides discussing how, from a process perspective, you can work to bring accessibility into your organization.
During the Q&A after (and hallway chats), I got some questions about how to motivate people within an organization to care about accessibility. I referenced my talk Selfish Accessibility (that links to the version I gave at Google in late 2015) that discusses one tactic, but please note that it may not apply for your organization.
