The technology acceptance model (TAM) is one of the most influential research models in studies of the determinants of information systems/information technology (IS/IT) acceptance. In TAM, perceived usefulness and perceived ease of use are hypothesized and empirically supported as fundamental determinants of user acceptance of a given IS/IT. A review of the IS and psychology literature, however, suggests that perceived usefulness can be of two distinct types: near-term usefulness and long-term usefulness. This paper reviews the concept of perceived usefulness and modifies TAM to include the two types of perceived usefulness. Data collected from nearly 285 administrative/clerical staff in a large organization were tested against the modified model using the structural equation modeling approach. The results of the study showed that, even though perceived near-term usefulness had the most significant influence on the behavioral intention to use a technology, perceived long-term usefulness also exerted a positive, though lesser, impact. No significant, direct relationship was found between ease of use and behavioral intention to use a technology. Implications of the findings and future research areas are discussed.
