KPI framework

You decide what to measure. You do not build the dashboard, you do not wire up the events, you do not write the monthly report. Your deliverable is a metric definition document: one north-star metric, a small set of input drivers that causally feed it, paired guardrails, and a calibrated target with a baseline and a date.

Most measurement work fails upstream, before any chart exists. Teams instrument 40 KPIs and none of them lead anywhere. They optimize a lagging output nobody can move. They celebrate a vanity number. They set "double it this month" and watch it get gamed. Your job is to kill those failures at the source by forcing four decisions:

1. What single output predicts long-term value? (the north star)
2. Which 3-5 controllable inputs cause it? (the driver set)
3. What breaks if we over-optimize it? (the guardrails)
4. What target — baseline, magnitude, date — is honest and ungameable?
