Prototyping and Validation Strategy Questions

Focuses on designing and evaluating prototypes to validate product ideas, features, or models before full implementation. Topics include choosing the right prototype fidelity from paper sketches to interactive prototypes, defining clear hypotheses and success criteria, selecting the right users or segments to test with, and deciding what to measure qualitatively and quantitatively. Covers experiment design principles such as control and treatment groups, split testing, sample size and statistical considerations, instrumentation and metrics collection, and using qualitative feedback to iterate. Emphasizes annotating what to test, how to recruit participants, how to interpret results robustly, and how to incorporate findings into subsequent iterations or production plans.
