Summary

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.

Abstract

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.
