This document provides an overview of design sprints, which are a five-phase framework that helps teams answer key product questions through collaboration, rapid prototyping and user testing. The phases are understand, sketch, decide, prototype and validate. Design sprints allow teams to reach goals quickly, encourage user-centered thinking and faster product launches. Research findings can be turned into a sprint challenge to action results. Activities include lightning talks, user sessions, how might we brainstorming, crazy 8 sketching, dot voting and prototype testing.
