Selected:Solution Interview ARID (Active Reviews for Intermediate Designs)Empathy Mapping Problem Interview

Criterion	Product Discovery Solution Interview	Architecture ARID (Active Reviews for Intermediate Designs)	UX Research Empathy Mapping	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.	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 a lot is assumed about a target group but little is seen jointly, empathy mapping makes knowledge and gaps directly comparable. The picture also shows which assumptions hold up and where evidence is missing.	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.
