Problem

Stock can age unnoticed when operators choose convenient pallets rather than the oldest eligible stock.

Solution

Sequence eligible inventory by receipt date, then direct operators to the oldest stock unless a documented exception applies.

What FIFO means

First in, first out prioritises the inventory received earliest. It is widely used where ageing, packaging changes or shelf life matter.

How to operate FIFO

Record receipt timestamps consistently, keep pallet or batch identity, and present the oldest eligible stock first during allocation and picking.

Exceptions

Quality holds, customer restrictions and inaccessible stock may override the normal sequence. Record the reason so the exception remains auditable.

Measure compliance

Review picks that bypassed older stock and investigate repeated location or process causes.
