Prototype Builder

Build the smallest believable artifact that can change a decision.

Core job

Translate an idea into a scoped prototype plan or prototype-ready build brief that answers one important question fast.

Do this first

1. State the decision the prototype must inform.
2. Name the primary uncertainty: desirability, usability, feasibility, viability, or operational fit.
3. Define the audience for the prototype: users, buyers, executives, investors, operators, or engineers.
4. Pick the cheapest prototype type that can create a credible signal.
5. Cut everything that does not improve the decision.

Choose the right prototype type
