Melanie Sumner: Why Continuous Accessibility Is a Strategic Advantage

Melanie Sumner, Product Accessibility Lead for Design Systems at HashiCorp, joins Robby to talk about what it takes to scale accessibility across legacy products—and how aligning design and engineering processes creates lasting change. Melanie shares her work making Ember.js more accessible, her team’s philosophy behind their design system, and why she treats accessibility like any other technical concern.

From the pitfalls of nested interactive elements to the strengths of Ember's conventions and codemods, this conversation offers a roadmap for integrating accessibility into every layer of product development.

Melanie also reflects on why she trademarked the term Continuous Accessibility, how it fits into product lifecycles, and what other frameworks can learn from the Ember community’s approach.

“Accessibility is a technical problem with a technical solution.”

Melanie joins us from Chicago, Illinois.
