| Criterion |  Product Discovery Opportunity Interview |  Product Discovery Solution Interview |  Product Discovery Opportunity Solution Tree |  Product Discovery Learning Card |
|---|---|---|---|---|
Purposedifferent | When opportunities are still hidden behind signals of need, it structures conversations around needs and obstacles. It looks for patterns that lead to new product opportunities. | When a solution idea is already on the table, it checks how it is understood and evaluated. It looks for resonance, objections, and missing fit early in the conversation. | When discovery keeps swinging between goals, ideas, and learning loops, it creates clear steering logic. It connects the desired outcome, opportunities, and experiments into a legible structure. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
