What problem does it solve? Teams facing a critical design challenge often spend weeks debating solutions or building untested features. This Skill structures the AJ&Smart Design Sprint 2.0 process, compressing the Google Ventures five-day sprint into four days (Map, Sketch, Decide, Test) so teams can move from a challenge statement to a user-tested prototype with validated findings. ## Core Features & Use Cases - Four-Day Sprint Facilitation: Guides Day 1 Map (HMW challenge framing, journey mapping, expert interviews), Day 2 Sketch (lightning demos, Crazy 8s, Art Museum voting), Day 3 Decide (supervote, assumption inventory, 10-16 panel storyboard), and Day 4 Test (prototype construction, five-user interviews, observation grid pattern analysis). - Evidence-Based Verdicts: Applies quantitative thresholds (>= 3 of 5 users for strong themes) to assign pass/fail/partial verdicts per sprint question with confidence classifications. - Cross-Framework Handoffs: Feeds validated findings to Lean UX hypothesis iteration, heuristic evaluation, and JTBD job stories. - Use Case: A product team unsure what to build for a new onboarding flow invokes the sprint to define the challenge, sketch competing solutions, select one via Decider supervote, and validate the prototype with five real users in four days. ## Quick Start Ask the /user-experience skill to run a design sprint for your product challenge, for example: "Facilitate a 4-day design sprint to validate our checkout redesign concept with real users."
