01Best for
When you want depth: many personas, broad problem exploration, clustered key problems, lo-fi prototypes tested and down-selected, a refined mid-fi prototype, and a buildable solution presentation.
Shape
Three diamonds: problem → exploration → refinement.
Best for
High-stakes work that warrants a full fidelity ladder.
Fidelity
Lo-fi prototypes diverse in kind, down-selected, then a mid-fi build.
Innovation
Creativity lenses push for at least one genuinely non-obvious concept.
Diverge → converge
Discover
Empathize broadly across distinct angles in a few real multi-persona councils. Surface lived problems and frictions; include a disconfirmation angle that tests the premise.
Define
Affinity-cluster the explorations into themes; name the key problem(s) and a sharp Point-of-View.
Ideate (Lo-Fi)
Generate many distinct, non-obvious concepts; build several lo-fi prototypes diverse in kind, including a deliberately extreme dark-horse.
Lo-Fi Test & Down-Select
Personas use the lo-fi prototypes in real sessions, then down-select to a shortlist to carry to mid-fi.
Refine (Mid-Fi)
Build mid-fi prototypes of the shortlist and explore concrete refinements, one per angle.
Deliver
Personas use the mid-fi prototype; synthesize the final solution presentation — winning concept, who it wins, validated solves, evidence trail, open risks, hand-off spec.
