| Criterion |  Architecture C4 Model |  Product Discovery Learning Card |  Product Discovery Smoke Test |  Growth Growth Experiment |
|---|---|---|---|---|
Purposedifferent | The C4 Model makes a system legible across several resolution levels, from context down to code. It suits situations where different audiences need to understand the same architecture from different altitudes. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. | 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. | 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. |
