A critical point for developing successful information systems for distributed organisations is the need for integrating heterogeneous technologies and tools. This paper reports a case study of integrating two key enabling technologies, namely workflow and document management. Integration is achieved by combining several approaches, including software engineering and hypertexts. In this way, we raise the integration problem from the level of a purely technical issue to a level of conceptual modelling: integration is not focused solely on the information/software systems but involves, and is driven by, the related business processes and the documents they deal with.
