| Criterion |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Product Discovery Learning Card |  Product Discovery Hypothesis Prioritization Canvas |
|---|---|---|---|
Purposedifferent | 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 Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. | When many hypotheses compete for attention, it brings order to their learning sequence and importance. It separates problem, assumption, solution, and evidence. The result is captured as a prioritization canvas and a hypothesis backlog. |
Complexitydifferent | High | Low | Medium |
Timedifferent | Several meetings plus preparation and analysis; total effort depends on scope | 25-40 min | 60-90 min |
Participantsdifferent | Evaluation team, architects, and relevant stakeholders | 1-5 | 3-8 |
