Principlev1
Build rough prototypes for immediate testing with affected
Build rough prototypes for immediate testing with affected users rather than perfecting solutions in isolation, because creative problem-solving requires feedback from material reality.
Why This Is a Principle
Derives from Generative Externalization (externalization through writing/making is generative) and Learning occurs when outcomes differ from predictions, (learning occurs when outcomes differ from predictions). The principle prescribes rapid prototyping with real-world testing as the mechanism for creative learning and problem refinement. It's actionable design guidance.
