Define the one metric that captures the value your product delivers — then pressure-test it against the five marks of a real North Star before your team commits to it.
A North Star Metric is the single number that best captures the core value customers get from your product — and a leading indicator of sustainable growth. Draft a candidate, score it, and map the inputs that move it.
Your North Star is the destination; input metrics are what your team actually pulls to get there. List 2–4.
The trap is picking a number that looks like progress but isn't. Revenue lags, total signups only ever climb, and "engagement" can mean anything. A real North Star reflects value customers actually receive, predicts revenue rather than reporting it, and moves when your team does good work.
Use it like this: one North Star for the whole product, reviewed rarely. Input metrics underneath it are what individual teams own and move week to week.
The honest caveat: no metric captures everything. The North Star focuses the org — it doesn't replace judgement, qualitative insight, or guardrail metrics that catch harm.
The North Star Metric guide breaks down how to find yours and avoid the classic traps — one of 151 frameworks on PM Mapped.
