 Definition of Inventory

The Institute of Logistics and Transport of London defines inventory as all the goods and materials held by an organization for sale or use, or a list of items held in stock.

Types of Inventory Management

According to Saxena (2003), in a production unit, regular inventories are divided into categories for effective operations and control.

Lonergan (2001) classifies inventory as raw materials, components, assemblies, sub-assemblies, work in progress and finished goods. However, Morrison and Jessop (2000) agree with above authors. They classify inventory as stock in trade, raw materials, equipment, spares, tools, gauges, fixtures, work in progress, packing materials, scrap and residues.

 Production Inventories

These are raw materials, parts and components that enter the firm‟s product during the production process. They may be of two general types; special items manufactured to the company‟s specifications and standard industrial items purchased of f the shelf.

Saleem (2004) explains that in production inventories timely and right supply of materials spares is important etc cutting down the investment on inventories and their carrying cost, achievement of economy in purchasing and avoidances loss during the storage process are subsequent.

Maintenance, Repair and Operation Inventories

Maintenance, repairs and operating supplies which are consumed in the production process but do not become parts of the final product, for example lubricating oil, soap materials and machine spare parts Lonerggan (2001) agues that the urgency of modern requirement and time cost of machines requires inventory control Time is money is the Golden rule today .

Requirements cannot wait nor can the machines and staff be kept in waiting since the cost of keeping them in waiting is more ,compared to cost of materials in store.

Work-In-Progress Inventories, Finished goods inventory

Semi finished goods/products found at various places of production operation. Morrison and Jessop (2000), argue that keeping inventory adds value to the organization in many ways, for example breaking bulk and smoothening operations.

Saleemi (2004) adds that a well-planned inventory scheme helps an efficient smooth and effective service delivery to customers a la lesser cost with the help of lower investment through planned but reduced inventories. Inventories help in avoiding unnecessary high working capital and also act as an insurance against errors in demand forecasts.
