Information Technology success factors are interpreted as a cumulative measure of multi-dimensional constructs within a socio-technical model in an organizational structure and warrant organizational acceptance from pre-implementation to post-implementation periods. We use a theoretical model based on the Cognitive Dissonance Theory (CDT) to measure perceived usefulness of Information Technology activities. The constructs play an important role in setting initial user expectations before Information Technology activities are rolled out in organizations. In this study, we surveyed physicians to measure the perceived usefulness of a multi-million dollar healthcare project. The analysis shows that computer expertise has a direct, positive effect and an indirect mitigating effect on end-user concerns on perceived usefulness. Ease of use was also found to have a negative effect on perceived usefulness.
