The Technology Acceptance Model (TAM) and Theory of Planned Behavior (TPB) are widely used in the information systems (IS) literature to explain and predict user technology acceptance behavior. Although these models have been utilized separately in the earlier studies, to increase the richness and predictive power of their studies, scholars have combined both theories in more recent studies. However, few studies have compared these models directly using the same empirical data. The justification for using various hybrid models is mostly anecdotal and convenient rather than based on strong theoretical arguments. Thus the question remains: when studying user technology acceptance behavior, …

We develop and test a theoretical model to investigate the assimilation of enterprise systems in the post-implementation stage within organizations. Specifically, this model explains how top management mediates the impact of external institutional pressures on the degree of usage of enterprise resource planning (ERP) systems. The hypotheses were tested using survey data from companies that have already implemented ERP systems. Results from partial least squares analyses suggest that mimetic pressures positively affect top management beliefs, which then positively affects top management participation in the ERP assimilation process. In turn, top management participation is confirmed to positively affect the degree of …
