A dashboard full of green can hide a business in trouble. Numbers don't lie, but badly defined ones mislead with total confidence.
The definition is the metric
"Active users," "revenue," "utilization" — each sounds precise and hides a dozen quiet choices. Active since when? Revenue booked or collected? Utilization of whom, against what baseline? Two teams reporting the same metric often aren't measuring the same thing, and the disagreement tends to surface at the worst possible moment — in front of a board, or after a decision's already been made.
A number is only as trustworthy as its answers to three questions:
- What exactly is counted, and what's excluded?
- Over what period, and compared to what?
- Who can change the definition — and would anyone notice if they did?
The dangerous metric isn't the one that's obviously wrong. It's the one that's slightly wrong and completely trusted.
Before you act on a number, make someone explain how it's calculated. If the explanation is fuzzy, the decision resting on it is fuzzier. Fewer numbers, clearly defined, beat a dashboard no one can fully account for.
