Criterion	Engineering Hypothesis-Driven Troubleshooting	Architecture ATAM (Architecture Tradeoff Analysis Method)	Product Discovery Test Card	Product Discovery Fake Door Test
Purposedifferent	When systems fail unexpectedly, spontaneous attempts often produce more noise than insight. Hypothesis-driven Troubleshooting translates symptoms into testable assumptions and makes troubleshooting learnable.	ATAM helps teams weigh architecture decisions when quality goals compete. The team considers business goals, stakeholder expectations, and technical decisions together. The evaluation shows which risks need further investigation.	The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success.	When demand is still unclear, it measures interest in a feature before it is built. It separates real behavior from polite agreement and deliberately keeps build effort small.
