You heard that A/B testing enables you to take a data-driven approach to product design and development. So you start running a few experiments on your UI, then a few more. Suddenly, you’re hooked. Before you know it, you’re conducting many concurrent tests and your app is full of complex, difficult to maintain conditional logic.

This session will explore approaches for managing the unique challenges and complexity that multivariate testing brings to building and maintaining a product. Some of the questions we’ll discuss are:

- What is A/B and multivariate testing?
- How do I build multiple A/B test experiences?
- What are the engineering challenges that come with maintaining multiple, long-running A/B tests?
- How can I simplify the conditional chaos that comes with the complexity of A/B tests?
- What are some design patterns I can employ for HTML templates, CSS and JavaScript?
