Metric map
One north star, four supporting signals
5 visual steps
A good north star sits in the center and gets stabilized by a small ring of supporting metrics that protect quality and learning speed.
Value deliveredHealthy retentionQuality guardrails
Signal 2
Retention depth
Track whether the behavior repeats often enough to indicate durable product pull.
Center
Primary value metric
Pick the one repeated action that best reflects user value delivered, not internal busyness.
Signal 3
Segment spread
Check whether improvement is broad or hiding inside one unusually strong cohort.
Signal 4
Efficiency guardrail
Protect cost, support load, or operational complexity while the main metric grows.
If the center metric rises while one of the outer signals collapses, you probably found a temporary win, not durable product value.
Good north star criteria
01- It reflects delivered user value, not internal activity.
- It can move often enough to guide weekly decisions.
- It forces tradeoff clarity across acquisition, activation, and retention.
Support metrics
02- Pair the north star with quality and efficiency guardrails.
- Track segment-level movement to avoid false confidence from blended averages.
- Review leading indicators that predict the main outcome earlier in the cycle.
Common mistakes
03- Picking a revenue-only metric before value creation is stable.
- Letting every team define a different top metric.
- Changing the metric too often to learn from it.
