What in your business only a person watching would catch, not a report?

Reports tell me what already happened. They almost never tell me what is about to happen if nobody steps in today. A client going quiet, a hire pulling back weeks before handing in notice, a location quietly underperforming while the numbers still look fine on paper. None of it showed up as a flag on any dashboard, someone just had to be paying attention closely enough to notice the shift before it became a complaint or a resignation letter.

Curious what the equivalent has been for people running more than one location, or more than one business at once. What is the thing that only ever gets caught by a person watching, never by a report sitting in an inbox?
