A design sprint is a 5-phase framework that helps teams answer critical business questions through rapid prototyping and user testing. The phases are: Map (understand the problem), Sketch (generate ideas), Decide (select the best concept), Prototype (build something testable), and Test (get user feedback). This process helps spark innovation, encourage user-centered design, align teams, and launch products faster. A key benefit is that it provides validated direction and user input to inform product development. Design sprints are best for when a team needs clarity on a new opportunity or is stuck on an issue.
