At Etsy, we push code over 30 times a day, we run dozens of experiments simultaneously and we have terabytes of data generated by the tens of millions of members of our community. We’ve worked hard to establish a product development process informed by — and often driven by — data. Of course, using data does not mean that decisions are easy or clear cut. In this talk, Nell will discuss the tensions that arise in such a data-informed product ecosystem, including tradeoffs between depth of understanding vs speed of iteration, making decisions with ambiguous findings, and the role of company values in interpreting statistical tests. Her talk will touch on the role of engineers, product managers, data scientists and analysts in making launch decisions, day after day, across web, mobile web, and four apps. She will also discuss the tooling behind this data driven culture, all built in house at Etsy.

Etsy is the world’s online marketplace for handmade and vintage goods. Etsy’s mission is to enable people anywhere to easily build and directly support independent, creative businesses.
