Towards an improved steering of design process in architecture

This paper presents a modelling of Design Process in Architecture: DPA. The goal of this modelling is to control the DPA. This modelling of DPA is based on a process-oriented approach of DPA. It is extended by a suggestion of a software architecture to steer DPA. Thus we State the foundations of a future tool, a kind of "manufacture software" able to evolve according to the requirements of each actor in DPA.
