Design Sprint

5-Day Structure (Google Ventures Model)

Monday: Understand

• Map the challenge (user journey, business goals)
• Expert interviews (15-20 min each)
• Define sprint question: 'Can we [desired outcome]?'
• Pick target: specific user + specific moment

Tuesday: Diverge

• Lightning demos (existing solutions, inspiration)
• Sketching: 4-step sketch (notes, ideas, crazy 8s, solution sketch)
• Silent critique: everyone reviews sketches with dot votes

Wednesday: Decide

• Sticky decision: vote on winning approaches
• Storyboard: map the prototype flow scene by scene
• Assign roles for prototype building

Thursday: Prototype

• Build a realistic-looking facade (doesn't need to work)
• Tools: Figma prototype, HTML/CSS, Keynote/Slides
• Realistic content (no lorem ipsum)
• Divide and conquer: each person builds sections

Friday: Test

• 5 user interviews, 1 hour each
• Interviewer + note-takers in separate room
• After each session: quick debrief
• End of day: pattern identification, decisions

When to Sprint

• New product or major feature (high uncertainty)
• Team disagreement on direction (need alignment)
• Tight timeline (compress weeks of debate into one week)
