Two tiers, one framework
Every lesson is built around the same Double Diamond. Tier 1 is included with any dthinkr account; Tier 2 is part of the paid plan.
The Double Diamond, explained
Five lessons on what design thinking is and how its four phases — Discover, Define, Develop, Deliver — turn fuzzy problems into clear action, plus a final multiple-choice test. Included with any dthinkr account.
The framework, inside dthinkr
Five practitioner modules that teach you to use the dthinkr tools — which agents to call in each phase and how to turn their output into real decisions. Requires the paid dthinkr plan.
The Double Diamond course
Five self-paced lessons, then a multiple-choice test to check it stuck. Sign in with your dthinkr account to open them — we recommend going in order.
Overview of Design Thinking and the Double Diamond
A guided tour of design thinking and the Double Diamond model — the shared language every later lesson builds on.
First Phase: Discover
Learn to explore the problem space before jumping to solutions — gathering real signals instead of guesses.
Second Phase: Define
Turn a heap of research into one sharp, shared problem statement the whole team can rally behind.
Third Phase: Develop
Generate a broad field of ideas, then twist and refine them into a shortlist worth building.
Fourth Phase: Deliver
Prototype fast and validate with real feedback before committing serious resources.
Final Assessment: The Double Diamond Test
Ten questions drawn at random from a pool of thirty, shuffled on every attempt — including scenario questions that check whether you can place a real situation in the right phase, not just recite the definitions.
Use dthinkr to solve real problems
Apply the framework with the dthinkr tools
Tier 2 shows you exactly how to run each Double Diamond phase inside dthinkr — which agents to call, in what order, and how to turn their output into decisions. It requires a dthinkr account and a paid subscription.
