| Criterion |  Product Discovery Smoke Test |  Product Discovery Test Card |  Agile Affinity Estimation |
|---|---|---|---|
Purposedifferent | 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. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | When many tasks need to be classified quickly, it sorts them by perceived effort and similarity. It reduces the effort of fine-grained estimation for large volumes. |
