What are the differences between Supply Chain Management and Warehousing?

Warehousing is an element of the the management of the supply chain. The two work streams are co-dependent and heavily reliant on each other. Without warehousing there can be no supply chain and vice versa, as such these two terms are constantly used at the same time. Each one has its own IT systems, work streams and reporting structures.

 

The management of a supply chain can be hard to define as it encompass the complete end to end processes and cuts across all elements both vertically and horizontally within the business. Warehousing, in comparison, can be easier to define and is controlled (primarily) by a Warehouse Management System


A warehouse management system (WMS) is a key part of the supply chain and primarily aims to control the movement and storage of materials within a warehouse and process the associated transactions, including shipping, receiving, putaway and picking. The systems also direct and optimize stock putaway based on real-time information about the status of bin utilization. A WMS monitors the progress of products through the warehouse. It involves the physical warehouse infrastructure, tracking systems, and communication between product stations. More precisely, warehouse management involves the receipt, storage and movement of goods, (normally finished goods), to intermediate storage locations or to a final customer. In the multi-echelon model for distribution, there may be multiple levels of warehouses. This includes a central warehouse, a regional warehouses (serviced by the central warehouse) and potentially retail warehouses (serviced by the regional warehouses). Warehouse management systems often utilize automatic identification and data capture technology, such as barcode scanners, mobile computers, wireless LANs and potentially radio-frequency identification (RFID) to efficiently monitor the flow of products. Once data has been collected, there is either a batch synchronization with, or a real-time wireless transmission to a central database. The database can then provide useful reports about the status of goods in the warehouse. Warehouse design and process design within the warehouse (e.g. wave picking) is also part of warehouse management. Warehouse management is an aspect of logistics and supply chain management.
