The changeover window is short and predictable
The value of a shift changeover is that it is the only time the amenities are genuinely empty and the only time they can be serviced properly. It is also short, which means the task list for that window has to be realistic. A crib room, locker area and washroom block can be reset in a defined period if the tasks are specific; the same window cannot also absorb floor treatment or detailed work on top of that.
Write the window tasks as a fixed list and keep it there. The temptation is to add one more item each time something is noticed, until the window no longer fits and the crew returns to a half-finished space. If additional work is needed, it belongs in a different window rather than squeezed into this one. Protecting the changeover list is what keeps the arrangement reliable week after week.
