Naming the touchpoints rather than describing them
A general instruction to clean touchpoints produces whatever each cleaner considers a touchpoint, which varies considerably. A named list does not: door handles both sides, push plates, handrails, light switches, lift buttons, bin lids, tap handles, dispenser levers, the specific items in this corridor. Naming them makes the work checkable and it makes an omission identifiable rather than arguable. Ambiguity in an instruction becomes variability in the work almost immediately.
The list is built at the walkthrough by walking the area and pointing at things, which produces a better list than any template. Corridors differ: one has a handrail and one does not, one has an intercom panel, one has a door that is held open and therefore never touched. Working from the real space is what keeps the list free of both gaps and irrelevant entries. Vagueness in an instruction turns into variation in the work almost at once.
