The Design Thinking Arc

A human-centered answer, earned stage by stage.

Last updated 2026-08-13

Design thinking runs on alternating modes: go out and learn, come back and make sense, diverge, make, test. Your Leefy tree is the come back half — the place where what you learned outside becomes structure you can act on.

Two of these five moves happen away from the keyboard entirely. That is not a gap in the tool; it is the method. The tree's job is to make sure nothing you learned out there evaporates.

  1. 1

    Empathize — outside Leefy

    Outside Leefy

    Talk to the people you are designing for. Interviews, observation, shadowing — done in the world, not in the app. Bring back raw notes and paste them into the tree as you go.

    You’re here when: The Empathize season is open and the tree holds assumptions rather than evidence.

  2. 2

    Define the insight

    Harvest

    Synthesize what you heard into a sharp point of view: who, needs what, because why. One banked artifact that the rest of the project answers to.

    You’re here when: The Define season is open and research notes are waiting to become a stance.

  3. 3

    Ideate against it

    Grow

    Grow branches wide against the defined need — volume first, judgment later. Cross-pollinate distant ideas; prune only when the season closes.

    You’re here when: The Ideate season is open and the point of view has few competing answers yet.

  4. 4

    Prototype the best

    Produce

    Pick the strongest idea and produce the cheapest thing that makes it testable — a sketch, a script, a mock. Rough on purpose; it exists to be argued with.

    You’re here when: The Prototype season is open and one idea has been chosen but nothing testable exists.

  5. 5

    Test — with people

    Outside Leefy

    Put the prototype in front of real users, outside the app. Bank what you learn on the tree — and let it send you back to whichever earlier stage it contradicts.

    You’re here when: The Test season is open and a prototype is ready to meet reality.
