Anatomy of a Design Sprint: What Actually Happens in 5 Days

Design sprints sound almost too good to be true: go from problem to tested prototype in five days. But after running over 40 sprints, we can confirm — they work.

Day 1: Map & Define

The first day is about alignment. We map the user journey, interview stakeholders, and pick a specific target to focus on. Most teams try to boil the ocean. A sprint forces you to pick one thing.

Day 2: Sketch

Everyone sketches solutions individually. No groupthink, no design-by-committee. We use Crazy 8s and Solution Sketches to generate a wide range of ideas before converging.

Day 3: Decide & Storyboard

The team votes on the strongest ideas and we create a storyboard — a step-by-step plan for the prototype. This is where the magic happens: hard decisions get made in hours, not weeks.

Day 4: Prototype

We build a realistic-looking prototype in a single day. It doesn't need to work — it just needs to look real enough to get honest feedback from users.

Day 5: Test

Five users test the prototype while the team watches. By the end of the day, patterns emerge. You know what works, what doesn't, and exactly what to build next.
