| Criterion |  Product Discovery Solution Interview |  Decision Making Eisenhower Matrix |  Architecture ARID (Active Reviews for Intermediate Designs) |  Product Discovery Problem Interview |
|---|---|---|---|---|
Purposedifferent | 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. | It separates true priorities from noise so it becomes clear what should be done now, scheduled, delegated, or dropped. | ARID examines how well developers can work with a technical design. It focuses on a part of the system that can still be revised, between the architecture overview and the detailed specification. | When the picture of the problem still needs to become solid, it asks about real situations and consequences. It separates genuine suffering from mere interest in a solution. |
