Prototype Testing

Also known as: Usability Testing, Product Testing, Beta Testing

Evaluation of early tangible versions of a product with real consumers to validate design, usability, and desirability before launch.

Prototype Testing is the evaluation of early tangible versions of a product—from physical mockups to functional prototypes—with real consumers to validate whether the design, usability, and value proposition satisfy the needs identified in research.

Unlike Concept Testing (which evaluates a described idea), prototype testing evaluates an artifact users can touch, use, and interact with. This generates rich qualitative insights about usage experience, usability friction, and improvement opportunities that don't emerge in declarative research.

Formats: low-fidelity prototype (mockup, wireframe), high-fidelity prototype (functional but simplified), and beta testing (near-final product with selected users).
