Information technology support is hard to find for the early design phases of the architecturaldesign process. Many of the existing issues in such design decision support tools appear to be caused by amismatch between the ways in which designers think and the ways in which information systems aim to givesupport. We therefore started an investigation of existing theories of design thinking, compared to the way inwhich design decision support systems provide information to the designer. We identify two main strategiestowards information system support in the early design phase: (1) applications for making design try-outs, and(2) applications as autonomous reasoning agents.We outline preview implementations for both approaches andindicate to what extent these strategies can be used to improve information system support for the architecturaldesigner.
