The issue of whether firms are receiving an adequate return on their investment in information technology (IT) continues to pervade managerial decision making. While productivity and other financial metrics are established hallmarks of IT investment evaluation, research has called for broader and richer metrics that can take into account the diversity of IT impacts. In this paper, we extend previous instrument development research to develop and test a process-oriented thermometer of IT business value using survey data based on executives' perceptions of IT impacts at multiple points along the value chain. Consistent with earlier research, we find that our process measures are sensitive to differences in industry, firm size, and business strategy. Through additional analysis of post-implementation reviews of IT impacts in four firms, we find consistency of within-firm perceptual measures among teams of senior executives, highlighting the potential for our thermometer to gauge the level of IT impacts within a single firm. We conclude that process-oriented perceptual measures can offer new and useful insights into IT impacts, complementing what we already know from firm-level objective metrics.
