prototyping-when-and-what

What problem does it solve?

It prevents teams from wasting time by choosing the wrong prototype scope, using the wrong fidelity, or continuing prototyping past the point where it should ship.

Core Features & Use Cases

• Guides what to prototype: Helps you select prototyping targets such as risky assumptions, disputed decisions, and high-investment choices.
• Helps choose the right fidelity: Aligns fidelity level to the question being answered (sketch, mockup, clickable, code, or production beta).
• Defines when to stop: Establishes stopping criteria and “good enough to ship” framing to avoid endless iteration and stakeholder confusion.
• Supports stakeholder communication: Teaches how to label fidelity, name what’s not built, and set timeline expectations to reduce misinterpretation.
• Proposes proven patterns: Covers common approaches like spike + commit, test-then-design, prototype-then-spec, and continuous prototyping.

Quick Start

Ask an AI to recommend what to prototype, what fidelity to use, and clear stopping criteria for a design phase given your specific decision, constraints, and remaining unknowns.
