|---|---|---|---|
Purposedifferent | When product teams track many metrics, the view of the actual customer outcome easily gets lost. A North Star Metric bundles growth, usage, and value contribution into one signal that makes the system's direction visible. | 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. |
