4.2.1 Why hold inventory: Inventory functionality

There are many reasons for a firm to hold inventory. We can look at some of the more obvious reasons of holding inventory:

• A retailer faces daily demand from its customers in the form of individual orders but he can only receive supply from the wholesaler in lumps or minimum order quantities because a wholesaler deals in volume trade, or because there are economies of scale in transportation costs. A retailer orders in batches and this results in inventories in the retail end.
• Inventories safeguard against the firm from running out of stock when there is a demand, and this is regarded as one of the key attributes of service.
• Inventories offer protection against fluctuations in demand and fluctuations in inventory replenishment time. They act as a buffer against uncertainty.
• A wholesaler supplying a retailer or a manufacturer supplying a wholesaler or distributor needs time to make the product ready for shipment. The ordering party must have enough inventory to keep the business running during this period. This builds up inventory in the system.

Bowersox et al (2001) provides a more technical description of the utility of inventory by coining the term 'inventory functionality', and his observations are provided in the following table.

Table 4.1 Inventory functionality

geographical specialisation	Allows geographical positioning across multiple manufacturing and distribution units of an enterprise. Inventory maintained at different locations and stages of the value creation process allows specialization.
decoupling	Allows economy of scale within a single facility and permits each process to operate at maximum efficiency rather than having the speed of the entire process constrained by the lowest.
supply/demand balancing	Accommodates elapsed time between inventory availability (manufacturing, growing, or extraction) and consumption.
buffering uncertainty	Accommodates uncertainty related to demand in excess of forecast or unexpected delays in order receipt and order processing on delivery and is typically referred to as safety stock.

Source: (Bowersox et al 2001)

The above description of inventory functionality has a strong manufacturing and distribution focus. In view of the integrated nature of supply chain management this is justified, but we will first need to look at the individual levels within the supply chain to see how inventory decisions are taken.
