Procurement is the act of acquiring, buying goods, services or works from an external source. It is favourable that the goods, services or works are appropriate and that they are procured at the best possible cost to meet the needs of the acquirer in terms of quality and quantity, time, and location. Corporations and public bodies often define processes intended to promote fair and open competition for their business while minimizing exposure to fraud and collusion. ==Overview== Almost all purchasing decisions include factors such as delivery and handling, marginal benefit, and price fluctuations. Procurement generally involves making buying decisions under conditions of scarcity. If good data is available, it is good practice to make use of economic analysis methods such as cost-benefit analysis or cost-utility analysis. An important distinction should be made between analyses without risk and those with risk. Where risk is involved, either in the costs or the benefits, the concept of expected value may be employed. Based on the consumption purposes of the acquired goods and services, procurement activities are often split into two distinct categories. The first category being direct, production-related procurement and the second being indirect, non-production-related procurement. Direct procurement occurs in manufacturing settings only. It encompasses all items that are part of finished products, such as raw material, components and parts. Direct procurement, which is the focus in supply chain management, directly affects the production process of manufacturing firms. In contrast, Indirect procurement activities concern “operating resources” that a company purchases to enable its operations. It comprises a wide variety of goods and services, from standardized low value items like office supplies and machine lubricants to complex and costly products and services;〔Lewis, M.A. and Roehrich, J.K.
