User Stories are a fantastic agile tool, but they are not the only way for the product owner and team to reach a mutual understanding of what needs to be delivered. This workshop explores the use of hypotheses and experiments from the Lean Startup community. We see how using hypotheses instead of stories brings advantages to the development team, the customer, and the user. Stop telling stories about your product - start asking questions.
