Today the need to be nimble in and adaptive to a turbulent business environment is greater than ever. Environmental intelligence is critical to making effective strategic decisions. Strategic decision-making is based on the collection and interpretation of information from the environment. Executives must continually scan and monitor the business environment for relevant and timely information. This paper argues that a hypermedia executive information system (HEIS) can provide facilities needed to support the process and products of strategic intelligence. HEISs extend traditional executive information systems (EISs). A HEIS is designed to facilitate reconnaissance in both the internal and external environments using hypermedia and artificial intelligence technologies. It is oriented toward business intelligence, which recognizes the need for managerial vigilance.
