Start with the areas nobody looks at
Every office has zones where the standard is effectively invisible to anybody who matters. Storage rooms, internal corridors between work areas, plant and communications rooms, rarely used meeting spaces and back-of-house circulation all fall into that category. Moving those from a daily to a weekly interval releases genuine time from the attendance and produces no observable change in how the premises look to anyone.
The same applies to detail tasks in occupied areas. High dusting, window sills, skirtings and the tops of cabinetry can move from a short interval to a longer one without anyone noticing for months. These are the reductions to make first, because they release time from work that was not contributing much to how the office is perceived.
