| Criterion |  Growth Growth Experiment |  Growth A/B Testing |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Product Discovery Learning Card |
|---|---|---|---|---|
Purposedifferent | When growth ideas surface quickly, the temptation to build immediately instead of learning is high. A Growth Experiment frames an assumption so target group, lever, and measurement are clear before the first deployment. | When two variants compete, discussions quickly decide by taste rather than effect. A/B Testing checks behavior under controlled conditions and separates real improvement from chance or expectation effects. | 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. |
