Why this works
The lesson behind the tool
When you reward a number, people optimise the number, not the goal behind it. A good metric changes decisions; a vanity metric only changes moods.
One North Star aligns the team on the value customers actually get, and pairing every target with a guardrail is how you avoid breeding cobras.
