|---|---|---|---|---|
Purposedifferent | Pretotyping clarifies whether a customer problem and solution idea create enough real demand. It separates problem, assumption, solution, and evidence, and captures the result as a pretotyping sketch, test setup, and conversion data. | 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 demand only needs to be roughly verified, it tests interest with minimal effort. It measures whether people would take a next step at all. |
