Without knowing current packaging quantities, delivery success, product loss and the return path, there is no way to measure what the new system improves.
| Field | What is recorded |
|---|---|
| Product flow | route, temperature condition, period |
| Single-use | quantity, rejection cause, product loss |
| Container service | filling, delivery, empty return, readiness again (by ID) |
| Return path | return points, wash capacity |
Pick one flow with known boundaries and compare the two methods over the same service unit and period. If the return and cleaning steps are undefined, buying durable containers does not complete the switch.
