Finding the transfer points rather than chasing the dust
The main paths are usually few and identifiable. A doorway held open by traffic, a shared corridor, clothing carried between areas, and air movement caused by pressure differences when a roller door opens. Watching where people and air actually move for half an hour reveals more than any amount of increased wiping frequency in the office, which treats the outcome rather than the cause.
Interventions follow the paths. A self-closing door that actually closes, matting at the transfer point, a change area used consistently, and scheduling floor work in the plant so it does not stir dust while administration is occupied. These are largely operational rather than cleaning measures, but the cleaning plan is often where the problem becomes visible and where the conversation starts. The cleaning arrangement can report what it observes and adjust its own sequence, but the durable fixes generally sit with the site.
