Challenging the hierarchical perspective on information systems: Implications from external information analysis

The strategic choices of organizations have traditionally been influenced by their environmental interactions. Consequently, the field of information systems has become increasingly concerned with providing managers with external information. However, such systems are largely based on research that was conducted prior to the important organizational and environmental changes of the late 1980s and 1990s. Much of this research focuses on hierarchical differentiation when providing information (especially external information) to managers. This paper presents the findings of a study that investigated the sourcing, dissemination and use of external information in organizations. The results show that managerial demand for such information is unrelated to managerial level, but is influenced by functional affiliation. The study also contradicts many of the previously held beliefs about managerial preferences for information channels and media. These findings have important implications for the field of information systems, especially personnel involved in systems design.
