Title: ASSESSING THE ECONOMIC IMPACT OF INFORMATION SYSTEMS TECHNOLOGY ON ORGANIZATIONS
Abstract: "The investment in information systems technology (IT) throughout the economy is enormous and increasing. The use of IT continues to shift from stand-alone, transaction processing type systems to data-managed systems, supporting diverse managerial and professional functions. Despite these facts, little progress has been realized in management's facility to measure the contribution of IT to the economic performance of their organizations. Traditional methods of evaluation, such as various forms of cost-benefit analysis, have proven effective in only limited situations.
This thesis investigates frameworks and procedures for assessing the economic impact of IT on organizations. The organization is modeled as an economic artifact engaged in production processes: a firm utilizes input resources, one being IT, to produce commodities which yield economic outputs, such as profits, revenues, ROI, market shares, etc. With this production view, the approach employs the microeconomic concept of production frontiers to generate a performance measure for the firms. This measure indicates the relative efficiency of the firms with respect to their utilization of resources. With IT expenditures isolated as separate input factors, the thesis develops procedures for determining the contribution of IT to performance.
Two studies investigate the effectiveness of the approach through a cross-sectional analysis of empirical data from two industry groups. In the first study, a non-parametric frontier analysis technique, known as data envelopment analysis (DEA), provides the framework for the analysis. In the second study, the DEA based approach is compared to one based on a more conventional, parametric approach. The two techniques are compared on their estimates of the performance ratings of the firms and estimates of the impacts of IT. The results of these studies are inconclusive with respect to the effectiveness of the framework and procedures. The strengths and weaknesses of the approach are discussed, as are the problems involved in doing any sort of assessment of the impacts of information technology."
