IT Governance and IT Risk Management Principles and Methods for Supporting 'Always-On' Enterprise Information Systems
Abstract
Most organizations in all sectors of industry, commerce, and government are fundamentally dependent on their information systems (IS) and would quickly cease to function should the technology (preferably information technology–IT) that underpins their activities ever come to halt. The development and governance of proper IT infrastructure may have enormous implications for the operation, structure, and strategy of organizations. IT and IS may contribute towards efficiency, productivity, and competitiveness improvements of both interorganizational and intraorganizational systems. On the other hand, successful organizations manage IT function in much the same way that they manage their other strategic functions and processes. This, in particular, means that they understand and manage risks associated with growing IT opportunities, as well as critical dependence of many business processes on IT and vice-versa. IT risk management issues are not only marginal or ‘technical’ problems but become more and more a ‘business problem.’ Therefore, in this chapter, a corporate IT risk management model is proposed and contemporary frameworks of IT governance and IT audit explained. Also, it is depicted how to model information systems and supporting IT procedures to meet ‘always-on’ requirements that comes from the business. In fact, a number of IT metrics proposed in the chapter support the alignment of IT Governance activities with business requirements towards IT.
