Broken Windows and Interesting Anomalies

Details matter more than founders want to believe. Rabois applies the broken-windows idea to companies: visible sloppiness, a dirty office, a buggy signup page, a shabby interview process, teaches everyone that sloppiness is acceptable here. Standards decay from small things outward. Sweat the food, the bathrooms, the error messages.

The last skill is noticing. When a metric does something weird, most people normalize it or explain it away. Great operators chase the anomaly, because anomalies are where reality disagrees with your model of the business.

His example: PayPal noticed a strange cluster of users, a seller doing volume no model predicted, power sellers on eBay. That anomaly became the company's entire strategy. The surprising data point you're tempted to dismiss may be your biggest opportunity wearing a disguise.
