At Netflix, all new UI features and changes to existing UI elements undergo rigorous A/B testing to measure their impact on the end user. This includes all non-trivial accessibility components. This presentation will investigate some of our (sometimes surprising) findings.
Netflix is one of the leaders in Big Data analytics and almost all new development is rigorously A/B tested before being productized. While experience, intuition, industry best practices and user studies provide valuable starting points, at-scale user testing often exposes surprising impact of even the smallest changes.
This presentation will investigate how small, innocuous changes to the UI can have surprising consequences, and how non-trivial accessibility improvements can affect the experience and behavior of the general user base as a whole.
