Participants will develop detailed solution concepts independently. They'll build on previous inspiration, create self-explanatory sketches for team review, and maintain anonymity to reduce bias.

• A solution sketch.


• A visualized, detailed concept.


• A foundation for a prototype.

Individual work is critical; no collaboration during this exercise. Anonymity is important to reduce bias in voting. The progressive approach (rough → rapid → detailed) works well. The 3-panel storyboard should tell a complete story without verbal explanation. Encourage self-explanatory sketches with labels and arrows. Thick markers force an appropriate level of detail. Some participants may want to perfect their sketches; remind them that 'good enough to communicate' is the goal. This exercise is typically followed by Art Museum and voting. It's best used after inspiration gathering (Lightning Demos) and problem framing (How Might We). This exercise combines divergent and convergent thinking.
