Warehouse Management: Processes, Systems and KPIs

Warehouse management is the control of all processes and stock in a warehouse, from goods receipt through put-away and picking to goods issue and stocktaking. It decides where each item is stored, in which order it leaves again and how every movement is booked, so that the stock in the system matches the stock on the shelf. While the warehouse is the place, warehouse management is what happens there: the processes, the systems that run them and the KPIs they are measured by.

The processes of warehouse management

• Goods receipt: checking the delivery against the advice or purchase order, counting and inspecting it, recording discrepancies and confirming receipt, for example on a goods receipt note.
• Put-away: assigning a storage location, moving the goods there and booking the location.
• Stock control: booking every movement, tracking batches and best-before dates and managing load carriers such as pallets, cages and containers.
• Picking: putting together the items of each customer order.
• Goods issue: packing, labelling, preparing the shipping documents, loading and booking the dispatch.
• Stocktaking: comparing the booked stock with the physical stock.

Where warehouse management meets transport

Warehouse management does not stop at the dock door; it plans the trucks too. Goods-in assigns staff and doors to the announced deliveries, and goods-out stages shipments in the order in which the vehicles arrive. If a delivery is not announced, or a truck arrives hours late, people and doors wait for nothing and the next slot moves. That is why many warehouses ask carriers to announce each truck with its number plate, reference and loading units, and note shortages or damaged pallets directly on the transport documents.

Storage strategies, systems and KPIs

Two decisions shape every warehouse: where goods are put and which unit leaves first. With fixed locations, each item has its own place; with random storage, goods go to any free place, which uses capacity better but needs an IT-based system that knows every location. Goods leave by FIFO (first in, first out), by LIFO (last in, first out), as in block storage where the front pallet covers the ones behind it, or by FEFO (first expired, first out), typical for food and medicines.

Small warehouses manage with lists and spreadsheets. Larger ones run a warehouse management system (WMS) that steers each step down to the single storage location, often with barcode scanners, and receives its orders from an ERP system; once the goods leave the gate, transport management takes over. Common KPIs are stock turnover, the share of orders that can be served from stock, picks per hour and the picking error rate, inventory differences and dock-to-stock time, the time from unloading at the ramp until the goods are stored and available. For carriers, good warehouse management shows at the ramp: short waits, shipments already staged in goods-out, and discrepancies recorded at once instead of claimed weeks later.
