What problem does it solve? Teams often spend months debating and building products without knowing if customers actually want them. This Skill compresses that risk into a structured five-day process that maps the problem, sketches solutions, picks a winner, builds a realistic prototype, and tests it with five real users before any production code is written. ## Core Features & Use Cases - Day-by-Day Sprint Facilitation: Step-by-step exercises for Map, Sketch, Decide, Prototype, and Test phases, including Crazy 8s, HMW notes, storyboarding, and the Five-Act Interview. - Decision & Prototyping Frameworks: Structured voting (heat maps, straw polls, Decider supervote) and guidance on building facade prototypes with tools like Figma or Keynote. - User Testing Playbook: Interview scripts, note-taking grids, and pattern-recognition methods for extracting clear findings from five customer interviews. - Use Case: A product team debating three onboarding redesigns runs a sprint: Monday they map the signup journey, Wednesday the Decider picks one solution, Thursday they build a clickable Figma facade, and Friday five target users reveal which flow actually works. ## Quick Start Ask the assistant to plan and facilitate a five-day design sprint for your product challenge, starting with Monday's mapping exercises.
