This presentation details the real-world journey of building a sustainable accessibility program by shifting from a reactive "fix-it" mode to a proactive culture where accessibility is integrated from the start. We will share practical strategies and key lessons learned, from building a compelling business case to implementing a two-pronged strategy for managing existing debt while building for the future. The talk will also introduce the concept of an accessibility maturity model as a tool for charting your course, with attendees leaving with a blueprint of actionable steps for creating lasting impact in their organizations.
