Where guesswork shows up first
It is rarely the dramatic theft story. It is the steady drift: pars that “everyone knows”, deliveries signed without a count, prep made on instinct, and write-offs that never get coded to a cause. Each item looks small until you multiply it across weeks and sites.

- Count what moves — start with top ten cost lines, not the entire storeroom on day one.
- Investigate quickly — variance should be discussed while service memory is fresh.
