Today, most organizations in all sectors of industry, commerce and government are fundamentally dependent on their information systems. In the words of (Rockart 1988): “Information technology has become inextricably intertwined with business.” In industries such as telecommunications, media, entertainment and financial services, where the product is digitized, the existence of an organization depends on the effective application of information technology (IT). The treasury management function of multinational companies provides another interesting example. Treasury management has developed during the last two decades from a simple function of protecting and enhancing cash flows, to a complex one, where all aspects pertaining to modern cash management, foreign exchange management, investment management, exposure management, risk-return analysis, and accounting are handled.
