# Design Sprint Framework A five-day process for answering critical business questions through design, prototyping, and testing ideas with customers. Developed at Google Ventures and used by Google, Slack, Airbnb, and hundreds of startups. ## Core Principle **Compress months of debate, design, and testing into one week — and test with real users before writing any production code.** The sprint replaces endless discussion with a fixed Monday-to-Friday spine, hard time-boxes, and a single Decider, so a high-stakes product question gets a real answer in five days instead of five months. ## Scoring **Goal: 10/10.** Score a sprint plan or execution by awarding 1 point for each item present and correct (10 total).

Monday produces a target customer and moment (not a vague "test the product"). 3. Hard time-boxes used (Crazy 8s in 8 min, 10am-5pm days, no open-ended sessions). 4. Solution sketches done alone and anonymous — no group brainstorming. 5. Wednesday ends with a single Decider Supervote, not consensus. 6. Storyboard specified before any prototype is built. 7. Prototype is a Goldilocks-fidelity facade, testable in 5-15 min, with a trial run done. 8. Exactly 5 target users recruited via screener (6 scheduled to absorb a no-show). 9. Friday uses the Five-Act Interview; users interpret the prototype unexplained. 10. End-of-sprint debrief ...
