If you build reporting infrastructure for a living, you've watched this happen.
Leadership picks a metric. The metric becomes a target. The target gets a dashboard. And then the number starts improving — while the thing the number was supposed to measure doesn't move at all. Sometimes it gets worse.
Everyone in the room knows. Nobody says it. The dashboard is green.
This pattern has a name — two, actually. Goodhart's Law (1975): when a measure becomes a target, it ceases to be a good measure. Campbell's Law (1976): the more a quantitative indicator is used for decision-making, the more it corrupts the very process it was meant to monitor. Two researchers, working independently, warned us fifty years ago. We built the dashboards anyway.
The case studies are brutal. Wells Fargo set a cross-selling target — eight accounts per customer — and wired incentives to it. Employees opened millions of unauthorized accounts. The metric hit its numbers right up until the moment it detonated. In the English NHS, an 18-week treatment target produced exactly what Bevan and Hood documented in Public Administration: delayed referrals to keep the clock from starting, minor procedures scheduled to reset it, easy cases prioritized while complex ones waited. Wait-time metrics improved. Waiting didn't.
Here's what fifty years of evidence says, and it's the same thing this series has been saying about federal rules: the metric changes what the organization reports. It doesn't change what the organization is. People don't game numbers because they're dishonest — they game them because the metric became the job, and the metric was never the job.
Every reporting requirement — a federal disclosure rule, a compliance program, a KPI on an executive dashboard — is a bet that measuring a thing will improve it. Fifty years of research says: only if the capacity and the culture underneath already point that way. Otherwise you get a green dashboard and a red reality.
You've seen this one. What was the metric?
