Experimenting on Humans - A/B Tests and Feature Toggles

Dalia Simons

How do you know what 100 millions users like? Wix conducts hundreds of experiments per month, on production, to understand which features our users like and which improve or damage our business. At Wix Engineering we have developed our 3rd generation experiments system called Petri, which is Open Sourced. Petri helps us maintain some order in a chaotic system that keeps changing. In this talk, Dalia explains how it works and what are the recommended patterns in conducting experiments that will have a minimal effect on performance and user experience.
