Product design sprint methodology 5-day

Run focused 5-day design sprints to solve big product challenges. Day 1 (Map): 1. Define long-term goal and sprint questions. 2. Map customer journey from start to finish. 3. Ask 'How Might We' questions and collect notes. 4. Target specific part of journey for sprint focus. Day 2 (Sketch): 1. Lightning demos of inspiring solutions. 2. Four-step sketching: notes, ideas, crazy 8s, solution sketch. Day 3 (Decide): 1. Present solution sketches anonymously. 2. Heat map voting and feedback. 3. Storyboard winning solution for prototype. Day 4 (Prototype): 1. Build realistic prototype (InVision, Figma). 2. Write realistic content, not lorem ipsum. Day 5 (Test): 1. 5 user interviews with prototype. 2. Document learnings and next steps. Team: 7 or fewer people, including decision maker. Outcome: validated or invalidated hypothesis with user evidence.
