The sticky-note layer.
Every audit we run, by the end of the second hour, the most important system in the practice has revealed itself: it is the layer of paper. Sticky notes on monitors, an index card under the keyboard, a printed sheet with handwritten margin notes, a Post-it on the fridge in the break room. Every one of them is a workaround for a coordination event the practice's software did not surface.
You can map a practice's revenue gaps faster by reading the sticky notes than by reading the PMS. The PMS will tell you what was billed. The sticky notes will tell you what almost wasn't.
It is a generous habit, kept up by people who care about the work. It is also a system the practice does not own and cannot scale — and the day the coordinator who wrote the notes stops working there, the practice loses something the software never knew was there.
