prototyping-pretotyping

SKILL.md

Test assumptions and validate ideas before investing in full development. Use cheapest/fastest method to answer key questions: Do people want this? Will they pay? Can we build it? Does it solve the problem? Pretotype (test idea with minimal implementation) before prototype (build partial version) before product (build full version).

Pretotyping (Alberto Savoia): Test if people want it BEFORE building it

List all assumptions (demand, pricing, feasibility, workflow), rank by risk (probability of being wrong × impact if wrong). Test highest-risk assumption first. See Common Patterns for typical assumptions by domain.

Use when testing ideas cheaply before building (pretotyping with fake doors, concierge MVPs, paper prototypes) to validate desirability/feasibility, choosing appropriate prototype fidelity (paper/clickable/coded), running experiments to test assumptions (demand, pricing, workflow), or when user mentions prototype, MVP, fake door test, concierge, Wizard of Oz, landing page test, smoke test, or asks "how can we validate this idea before building?".
