Framework · Double Diamond

Frame an ambiguous problem, then take it to a buildable solution.

Problem space (Discover fan → Define waist) then solution space (Develop fan + prototype → Deliver waist). Diverge widely to find the real pain, converge on one sharp point of view, explore solutions, and converge on a spec personas have actually used.

01Best for

When you have a How-Might-We question and want a rigorous problem framing plus a tested, buildable solution spec.

Shape

Two diamonds: problem space, then solution space.

Best for

Taking an ambiguous HMW from real pain to a buildable spec.

Gates

Convergence is refused until enough diverse personas have weighed in.

Engine

Seeds the analyze → act → verify plan; loops Deliver back to Develop.

Diverge → converge

01

Discover

Surface the real, lived pains broadly across personas and angles. No solutions yet — anti-steering is strongest here.

02

Define

Cluster the breadth into one core problem and a sharp Point-of-View, then frame the next How-Might-We.

03

Develop

Generate multiple solution candidates from the POV and build at least one real, minimal prototype.

04

Deliver

Personas actually use the prototype, then converge to a buildable spec — must-haves, who-for, validated solves, open risks.

02Run it for
