Ranking by consequence rather than by room
The instinct is to work through a premises room by room, which is efficient in terms of movement and poor in terms of outcome when time is short. If the window closes with two rooms untouched, the outcome depends entirely on which two rooms those were. Ranking the tasks by what a missed item actually costs produces a much better result from the same forty-five minutes.
In most small suites the ranking is fairly consistent. Washrooms and waste top the list because their absence is noticed immediately and matters most. The kitchen follows, then the client-facing area, then general floors, then detail work such as sills, skirtings and internal glass. Writing that order down means it is applied consistently rather than reconstructed under time pressure.
