An order picking method where a single picker picks all of the items for a single order.
An individual unit picked during piece picking.
EPC (Electronic Product Code)
A globally unique serial number for physical objects identified using RFID tags.
ERP (Enterprise Resource Planning)

GPC (Global Product Catalogue)
A directory of product attributes that allows independent data repositories to be synchronized for global, multi-industry supply chain messaging and reporting.
GTIN (Global Trade Item Number)
All-numeric system for assigning globally unique codes to trade items (products and services). GTIN includes UPC, ISBN, and NDC.
Package used inside of a carton to allow more efficient split-case picking instead of individual piece picking when a less-than-carton-size number of units are to be picked.
Inventory master file
File maintained by a WMS that contains the total quantity and storage locations of each items stored in the warehouse. Used together like the location master file to control material transport operations.
The number of units of each item stored in a warehouse.
ISBN (International Standard Book Numbering)
An international standard code for books.
Grouping of identical objects, i.e., a class or collection of units; inventoried items are usually referred to as stock-keeping units (SKUs).
An item-quantity pair in an order.
Location master file
File maintained by a WMS that contains the quantity of the item available at each storage location in the warehouse. Used together with the inventory master file to control material transport operations.
A single identifiable unit load (e.g. carton, pallet, trailer, etc.) that is moved between and stored at a location.
NDC (National Drug Code)
A code maintained by the FDA for identifying prescription drugs and some over the counter drugs.
The process of removing material from storage in response to specific customer orders or ship orders (cf. putting).
Request to ship, receive, or transport material as indicated in a customer order, purchase order, or shop order, respectively.
The process of preparing a container for shipment.
Retrieval of full pallets of cartons, or layers of cartons from a pallet (a.k.a. unit-load picking).
A non-powered conveyor (e.g. wheel or roller) used in piece picking to support a tote or other container while it is being filled.
Short for order picking (cf. putting).
Request to a picker that indicates the sequence in which the storage locations of SKUs are to be visited along with the quantity of units to be picked from each location for one or more orders.
Alternative term for progressive assembly picking.
Retrieval of individual units (or 'eaches') of an item, where each piece picked is the unit of issue to the final customer (a.k.a. broken-case picking).
Progressive assembly picking
Variation of zone picking where a order is passed from one zone to the next, eliminating the need to consolidate the order but increasing its total picking time (a.k.a. pick-and-pass).
Request that indicates the type and quantity of items to be received from a vendor; each item-quantity pair in the order is termed a line (cf. customer order and shop order).
The process of moving material from a receiving area to a storage location.
The process of unloading, verifying, inspecting, and staging of material transported to a warehouse in preparation for putaway or cross-docking, sometimes including sorting and repackaging of the material.
The process of moving material from reserve storage to a forward picking area.
An area intended for the storage of material in full pallet load sizes from which both forward picking areas are replenished and pallet orders and some case orders are picked.
The process of moving items to different storage locations to improve handling efficiency.
The process of staging, verifying, and loading orders to be transported from a warehouse.
Request that indicates the type and quantity of SKUs to be transported from a warehouse to a production area; each SKU-quantity pair in the order is termed a line (cf. customer order and shop order).
Variation of zone picking and where the items for an order are picked simultaneously in each zone and then consolidated, making it possible to minimize the total picking time required for an order (which is useful if there are multiple waves per shift).
The process of merging, identifying, inducting, and separating material to be conveyed to specific destinations.
Variation of case picking where inner packs of items from cartons are retrieved.
SSCC (Serial Shipping Container Code)
A globally unique serial number for identifying a movable unit (e.g., a pallet).
SKU (Stock-keeping unit)
An inventoried item.
An identifiable location in a warehouse assigned a unique address and used to store a single item, where the capacity of the location corresponds to the maximum number of units of the item that can be stored at the location.
A powered conveyor (e.g., belt or live roller) used in piece and case picking to transport completed orders.
Either a single unit of an item, or multiple units so arranged or restricted that they can be handled as a single entity and maintain their integrity.
Instance of an item, i.e., a unique physical object.
The process of combining multiple smaller containers into a larger container that can be handled as a single unit load.
Alternate term for pallet picking

UPC (Universal Product Code)
The standard bar code for retail items in North America.

WMS (Warehouse Management System)
Software system that enables real-time, paperless control of the operations of a single warehouse.
An order picking method where each picker only picks the items of an order that are located in the portion of the storage area assigned to the picker for picking; simultaneous picking and progressive assembly picking are two variations of zone picking.
A combination of zone and batch picking, where multiple pickers each pick portions of multiple orders.
