Slotting

The strategic assignment of storage locations to products within a warehouse to maximise operational efficiency.

Full Definition

Slotting is the process of determining the optimal placement of each SKU within a warehouse, taking into account factors such as pick frequency, product velocity, weight, dimensions, and storage type. Effective slotting reduces travel time for pickers, minimises ergonomic strain, and improves throughput. It is distinct from putaway, which is the physical act of placing goods in an assigned location. Slotting decisions are typically made by logistics engineers or WMS algorithms. Editors should note that 'slotting' is a gerund/noun form of 'to slot'; 'slot optimisation' is a related but distinct concept.

Usage

Usage note: Distinguish clearly from 'putaway'. Slotting is a planning activity; putaway is an operational activity.
