Based on the overall flow of materials, companies can be seen as being composed of three
primary processes: purchasing, manufacturing and distribution (Thawiwinyu and Laptaned,
2009). In the parlance of purchasing, direct procurement addresses all components and raw
materials that are used in the manufacturing process of a finished product such as sheet
metal, semiconductors and petrochemicals, whereas indirect procurement relates to
products and services for Maintenance, Repair and Operations (MRO), and focuses on
products and services that are neither a part of the end product, nor are resold directly
(Puschmann and Alt, 2005).
For companies to remain cost-competitive in the market, they must reduce the costs
of their components and materials by sourcing from least-cost suppliers. One method to
achieve this is through open bidding via the Internet (Yu et al., 2008). This migration of
procurement functions to the Internet is known as e-procurement. Scholars have defined
e-procurement as an “Internet-based purchasing system that offers electronic purchase,
ordering processing and enhanced administrative functions to buyers, suppliers (Panayiotou
et al., 2004) and management” (Atkinson, 2007). In basic terms, e-procurement can be
defined as “using Internet technology in the purchasing process” (Boer et al., 2002).
e-Procurement is changing the way businesses purchase goods. Nowadays, since most
products and services are procured using electronic data interchange and the Internet, the
application of e-procurement is inevitable in both manufacturing and services
(Gunasekaran and Ngai, 2008). e-Procurement is gaining popularity in business practice
and the benefits encourage its adoption in a variety of areas, including IT purchases.
(Ronchi et al., 2010).
