Utilization is the whole game

Part 01 ended on an assumption worth pulling apart: that the surveyor is busy all day. Almost nobody is, and the shortfall does not show up anywhere in a P&L. It shows up as a cost per survey that keeps drifting up while everyone insists nothing changed.

Here is a Tuesday. Two jobs booked, a third slot open because a homeowner moved to Thursday.

Twenty-four percent. Nothing went wrong on this Tuesday. Nobody was lazy, no truck broke down, the weather was fine. One homeowner rescheduled and one was not home, which is a normal week, and the day still returned under two hours of the work the customer is actually paying for.

The surveyor was not underworked. The day was.

Why this is the number that matters

Because every fixed cost in Part 01 divides by it. The truck costs the same on a two-survey day as on a four-survey day. So does the insurance, the tablet, the salary. Utilization is the denominator under all of them at once, which is why a ten point swing in booked density moves cost per survey more than any wage negotiation you will ever have.

It is also the number that is hardest to fix from the inside. The levers are real but slow: tighter geographic clustering, a scheduler who batches by zip rather than by request order, confirmation calls that actually reduce no-shows, a capture standard that stops sending people back. Every one of those is a quarter of work, not a week.

Run your own Tuesday

The reason outsourcing changes the arithmetic

Not because somebody else's surveyor is cheaper per hour. Usually they are not. It is because the idle minutes stop being yours. A dead slot on a partner's Tuesday is a cost they absorb across a national book of work, and the density they can build across many customers in one metro is density a single installer cannot build from their own pipeline alone.

That is the entire structural argument, and it is worth stating plainly because it is often oversold. Outsourcing converts a fixed cost into a variable one. That is good when your volume moves and bad when it does not. If your volume is flat, high and geographically tight, an in-house crew running at genuine density is hard to beat, and you should keep it.
