The Technology Acceptance Model, popularly known as the TAM, has been widely used in the information systems literature to explain individual adoption of information technology. In the late 1990’s, and the early part of this century, a number of studies either extended the model by identifying antecedents to technology acceptance or have replicated and validated the model. An aspect that has captured the interest of information systems researchers is the role of culture in the acceptance, adoption, and diffusion. We examine the role of espoused organizational culture traits in technology acceptance, adoption and diffusion, that is, we consider organizational cultural values to be antecedents of TAM. We empirically test this model in an e-government setting in a developing country and report on our findings.
