The operations system that sees every locker at once: which cells are occupied, what has been sitting too long, and which machine needs attention.
Why this
Where the parcel is, without a phone callThe system holds the full overview — statistics, reports and a status for every parcel. "Where is my parcel" gets answered from a screen, not by ringing the driver.
Couriers run from the same placeCourier management sits in the same system as the lockers. Whoever plans the route sees the same lockers and parcels the driver will fill and empty.
