Multi-tenant warehouses around Bangkok often share aisle numbering schemes that look tidy on a floor plan and messy on the ground. A bin code only helps if every picker reads it the same way under fluorescent light at 6 a.m.
Walk one aisle per week with a printed location list. Confirm that the physical placard matches the ledger, that overflow is not sitting in the wrong bay, and that temporary floor stacks have a written home.
When tenants rotate space, orphan locations appear. Mark retired bins as inactive in the ledger the day the lease line moves; otherwise cycle counts keep inventing stock in empty air.
During mapping visits we ask managers to photograph each placard once a quarter. The photos settle arguments faster than memory when a picker swears the location used to be two bays left.
Hygiene is dull work. It is also the cheapest way to keep inventory intelligence honest before you invest in larger reporting changes.
