Kylie Castellaw
Maryam Aidini

If you’ve ever worked on a software delivery team, it’s likely you know the challenge of having to build a large, complex feature without knowing if it’s the right thing to do or if it will deliver the anticipated value. This is especially concerning if your team is investing a lot of time and effort. The good news is that there’s a way to minimize risk and ensure you’re moving forward with the right feature.

Join experts Kylie Castellaw and Maryam Aidini to learn how to apply the practical technique of hypothesis-driven software development. You’ll discover how to find initial data for your user stories and ensure you’re moving in the right direction. Along the way, you’ll walk step-by-step through an actual case study that shows how to create a framework to evaluate the success of a product and set metrics for each task and user story.
