The room is ready and the desk does not know

On a busy changeover day the constraint is not cleaning capacity. It is the delay between a room being genuinely ready and the desk knowing it, during which an arriving guest waits in the lobby.

Twenty minutes, repeatedly

Each individual delay is small and forgivable. Across a full changeover it adds up to rooms sold late, guests waiting, and a desk that starts guessing readiness to keep the queue moving — which produces the worse failure of sending someone to a room that is not ready.

Status at the room

Updated by the person who did the work, where the work happened. Anything requiring them to return to a desk or find a supervisor reintroduces the delay it was meant to remove.

Turnaround as a number

Once status carries timestamps, turnaround per room becomes visible. Hotels usually find the variation is by floor or by shift rather than by person, which points at supply logistics rather than at effort — and that is a fixable, blameless finding.
