In recent years a number of organisations have implemented executive information systems (EIS) in order to improve the performance gains on their executives’ job. Although the use of EIS is important to executives, majority of executives are unwilling to use EIS because of their design failures. By using social factors, habits and facilitation conditions variables from Triandis’ framework, this paper extends the Technology Acceptance Model (TAM) to derive useful variables to address the problem of the low usage of EIS by executives. This paper reports on the research in progress in Australia on the adoption and usage of EIS by executives. The preliminary results suggest that executives’ experience in EIS positively relates to their experience in computer-based information systems. The results also suggest a high degree of perceived usefulness, perceived ease of use as well as positive attitude towards using EIS. Further, the results suggest that executives consider social factors in using EIS in their work. Moreover, the results suggest facilitating conditions variables such as EIS development process; EIS management process and organisational environment are strongly related to the adoption and usage of EIS by executives. Finally, the results suggest a high degree of EIS usage by middle managers than top-level managers, which EIS meant to support.
