Criterion	Product Discovery Problem Interview	Architecture LASR (Lightweight Approach for Software Reviews)	Product Discovery Test Card	Product Discovery Assumption Mapping
Purposedifferent	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.	LASR helps development teams identify where their software falls short of important quality goals and which improvements to consider. A small group with existing system knowledge can make an initial assessment and investigate open questions in more detail.	The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success.	When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first.
