Five numbers, every Monday, no exceptions

The operators who run the best companies share a small habit: every Monday morning, five numbers, the same five numbers, shipped to themselves before anything else.

The five are different for every business. Common ones: trailing four-week revenue, new customer count, gross churn count, cash in the bank, burn. The goal isn't to act on each number every week. The goal is to notice when one of them drifts.

Drift is silent. By the time a quarterly review surfaces it, the drift has been running for 10 weeks. Five numbers on Monday catch it in week two.

It's a ten-minute habit that replaces a six-hour crisis meeting three times a year.
