| Criterion |  Growth Flywheel |  Product Discovery Test Card |  Growth Growth Experiment |  Product Discovery Learning Card |
|---|---|---|---|---|
Purposedifferent | 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. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | 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. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
