- WMS (Warehouse Management System):
- A warehouse management system (WMS) consists of software and processes that allow organizations to control and administer warehouse operations from the time goods or materials enter a warehouse until they move out.
- Warehouses sit at the center of manufacturing and supply chain operations because they hold all of the material used or produced in those processes, from raw materials to finished goods. The purpose of a WMS is to help ensure that goods and materials move through warehouses in the most efficient and cost-effective way. A WMS handles many functions that enable these movements, including inventory tracking, picking, receiving and putaway.
- A WMS also provides visibility into an organization’s inventory at any time and location, whether in a facility or in transit.
- The WMS knows where the required materials are stored and controls the supply and disposal of material as well as the transport between the production lines.
