| Criterion |  Product Discovery Working Backwards |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Product Discovery Smoke Test |
|---|---|---|---|
Purposedifferent | When the target state and benefit need to be clear first, it thinks backward from the desired outcome into the product logic. It sharpens vision, objections, and value proposition before elaboration. | 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. | When demand only needs to be roughly verified, it tests interest with minimal effort. It measures whether people would take a next step at all. |
