4.2 Inventory: Basic concepts

The following discussion will help you refresh your knowledge about inventory management.

Inventory types and characteristics. The management of inventory requires skill as the management of inventory has serious implications for the firm's operational and financial performance. The types of risks associated with inventory are, however, different for firms at different stages in the supply chain. The typical measures of inventory commitment are time duration, depth and width of commitment (Bowersox et al 2001).

Manufacturers. The manufacturer's inventory risk is long and the commitment starts from raw material or component to finished product through the work- in process.

Wholesaler . A wholesaler purchases large quantities from manufacturers and sells in smaller quantities to retailers. The wholesaler provides retail customers with assorted merchandise from various manufacturers in specific quantities. A wholesaler often must take an inventory position well ahead of the selling season in consideration of seasonal fluctuations and imbalance between demand and supply during a particular period. This increases the depth and duration of his risk.

A retailer. For a retailer, inventory management is about buying and selling velocity. A retailer deals with a wide variety of products. The risk is wide as it is spread over a wide range of products, but the risk with respect to any individual product is not deep.
