The document describes how to conduct a design sprint, which is a five-day process for building and testing a prototype. It involves setting the right challenge and team, then mapping out user journeys. The team sketches solutions, decides on a top solution, prototypes it, and tests it with users. The goals of a sprint are to answer vital questions, create prototypes and user testing reports, and validate hypotheses before fully developing a solution. Conducting sprints in this focused, time-boxed way allows teams to quickly iterate on ideas.
