Over the past two years, PayPal has been on a journey to modernize its internal development and test systems, from test environments, implementing enterprise continuous integration and code propagation into the development pipeline, to release processes and production code validation. Jose Buraschi and Nir Szilagyi will talk about transforming the code of 5,000 developers across 350 teams and how it required social “magic” to influence behaviors and motivate engagement. This modernization of PayPal's development practices has involved creating reliable integrated test environments, continuous integration, automated code propagation, and automated validation before each deployment. Instead of asking for a list of things developers need to do differently, Jose and Nir asked for simple changes that, through side effects, led to the desired results.

In agile, everything we do is an experiment. Product development is no different. We think we know what the customer wants, and the customer thinks they know what they want, but it turns out we're all wrong! To get to validated discoveries about our features, we must understand how to write a better hypothesis for our development experiments. This session focuses on challenging the mindset that we are validating options during our experiments. Natalie Warnert will show you how to eliminate options that don't work with data and feedback by looking at your product hypotheses as tests that cannot be proven. This way of testing your product design preserves options and helps to eliminate choosing the wrong thing because of your confirmation and customer biases. Natalie will present key metrics you can use to help guide your experiments and practical ways to look at your ideas as something to test, rather than validate.
