This paper presents a field study of the Technology Acceptance Model. We extended this
model to predict the acceptance of a multifinctional, broker workstation with a windowed
interface. Brokers and sales assistants in the private client group of a major investment
bank use this workstation as an integral part of their jobs. The extended model explains a
significant percentage of the variance in usage, but the variables that are most salient in the
model differ between brokers and sales assistants. There is evidence that low performing
brokers use the workstation more than higher performing brokers; the results also suggest
that more training may be needed for sophisticated workstations for professionals than for
clerical personnel learning to use transactions processing systems. We believe it is
important to predict and understand the acceptance of technology like the workstation in
this study if firms are to obtain a return from investing in information technology.Information Systems Working Papers Serie
