This walks you through the classic 5-day design sprint framework, from framing the challenge on Monday to testing a prototype with real users on Friday. It covers the full structure (understand, diverge, decide, prototype, test) plus variations like mini sprints and remote adaptations. You get checklists for prep work like recruiting testers and blocking calendars, plus the core best practices like keeping the decision maker in the room and banning devices during sessions. Honestly most useful if you're facilitating sprints for the first time or need to explain the process to stakeholders who've never done one. The framework itself is well established, so this is more reference material than novel methodology.
