Executive Information Systems (EIS) grew out ofthe information needs of top executives. The recent literature reports that EIS usage has spread throughout organisations. Web-based technologies are causing a revisit of existing IT implementation models, including those for EIS. These technologies include: Intranet, Internet, Extranet, e-Commerce: Business-to-Business (B2B), e-Comrnerce: Business-to-Consumer (B2C), Wireless Application Protocol (WAP) and other mobile technologies. The author conducts a field study of 31 well-established organisations in KwaZulu/Natal, South Africa, which have EIS experience. A validated survey instrument is administered to an EIS stakeholder in each organisation surveyed. This dissertation reports on (1) an investigation into previous research on IT adoption; (2) that there is little evidence to support that the theoretical usage aspects of the Technology Acceptance Model (TAM) are echoed in EIS implementations in KwaZulu/Natal; and (3) identifies and ranks Web-based technologies in order of their perceived impact on EIS currently and in the future. There is a positive impact level trend for all Web-based technologies on future EIS implementations. The results from this field study could be useful in formulating a set of management perspectives for organisations in South Africa wishing to embark on EIS implementation programs.
