Two kinds of window, two kinds of task
Between-session windows are short and frequent. They support a defined turnaround only: bins emptied where needed, desks and benches wiped, whiteboard cleared, floor spot-checked, furniture returned to layout. Attempting more in a twenty or forty minute gap produces a partial job in every room rather than a complete one in a few, which is worse for the building. Deciding which rooms fit a short window and which do not is the first thing the scope should settle.
End-of-day windows are long and support the substantive work: floors, detailed surfaces, glass, amenities in full and the rotating periodic items. The scope should assign each room to one or both, and be explicit about which tasks belong in which window. A room appearing in both should have two distinct task lists rather than one that is performed to varying depths. Listing the room against both windows with two lists is clearer than one line qualified by circumstances.
