Evaluation of information systems investments: towards multiple perspectives
Computer-based information systems are difficult to evaluate. Information technology (IT) is pervasive in the manufacturing and service sectors: most organizations depend on computers for their routine data-processing operations, and systems designed to give a ‘competitive edge’ are increasingly common. But successful utilization is by no means automatic. Appraisal of costs and benefits is necessary if value for money is to be obtained from existing information systems and plans made for future applications. Improvements in business performance due to information systems can be extremely difficult to measure, however. Benefits are often qualitative and uncertain, costs diffuse. That this is a hot topic is demonstrated by the fact that there is now software on the market to help in assessment of computing facilities. Yet as other contributors to this book demonstrate, there is no commonly accepted framework or methodology for information systems (IS) evaluation.
