The collaborative design of business and information systems touches a number of issues that lie within the realm of different research areas. It deals with design as such and in particular with design in and for groups. It is also concerned with socio-technical systems and hence with human-computer interaction as well as IT-mediated human-human interaction. This introduces collaboration issues. The significant complexity of the business and information systems that are in the focus of the design endeavor calls for modeling as an instrument for managing this complexity. This paper maps the terrain of collabora- tive design of business and information systems by surveying the contributions that are made by related areas of research.
