Abstract
A distinction is made between coherence- and correspondence-driven work domains. This novel domain taxonomy is used to argue that the widely accepted goal of making the interface representation compatible with the user's mental model is not always appropriate. For correspondence-driven domains, it is more meaningful to constrain design from the side of the work domain rather than from that of the user. The implications of the coherence/correspondence distinction for the modelling of work domains, for interface design in computer supported co-operative work, and for the development of a multidimensional taxonomy of work domains are also briefly pointed out. The discussion suggests that the correspondence/coherence taxonomy provides a powerful conceptual tool for addressing fundamental issues in human-computer interaction.
