| Criterion |  Product Discovery Test Card |  Growth Flywheel |
|---|---|---|
Purposedifferent | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | Growth often breaks down where a reinforcing mechanism builds up too much friction. A Flywheel shows the cycle of value, repetition, and reinforcement meant to sustain growth. |
Complexitydifferent | Low | Medium |
Timedifferent | 20-35 min | 60-120 min |
Participantsdifferent | 1-5 | 3-8 |
