Senior executives' use of information technology

There is a paucity of literature focusing on the ingredients for effective top management, i.e. senior executives, use of Information Technology (IT). In practice, many senior executives argue that they do not see a connection between what IT does and their tasks as executives. Based on the Technology Acceptance Model (TAM), a research model was developed and tested to assess the factors that in¯uence the use of IT by senior executives. A dedicated system supporting the task of a senior executive, an Executive Information System (EIS), was used as the IT tool under review. A large number of external variables were identi®ed and hypothesized, in¯uencing the core elements of TAM. To test the research model using structural equation modeling, cross-sectional data was gathered from eighty-seven senior executives drawn from twenty-one European-based multinationals. The results supported the core TAM and found only a small number of antecedent variables in¯uencing actual use, either directly or indirectly. In addition to identifying the external factors, three of these key variables are under managerial control. They can be used to design organizational or managerial interventions that increase effective utilization of IT.
