Davis' (1989) Technology Acceptance Model (TAM) is a well-known, validated model originally intended to predict and explain the acceptance of end-user technological products such as PC systems and software packages. This research represents an initial exploration into the ability of the TAM to predict and explain the acceptance of a radically new technological process, object-oriented systems development (OOSD). The results obtained from a sample of 160 experienced developers indicates that, with some slight modification, the scales used for the TAM are reliable and valid for measuring the usefulness and ease of use of OOSD methods.
