Modeling is a key activity in conceptual design and system design. Users as well as stakeholders, experts and entrepreneurs need to be able to create shared understanding about a system representation. Technology like interactive whiteboards may provide new opportunities in the support of collaborative modeling. We conduct an exploratory research on experiences in using interactive whiteboards in collaborative modeling, based on semi-structured interviews. This paper offers a first overview of advantages and disadvantages of interactive whiteboards and creates a research agenda to explore how process support can help in harvesting the efficiency gain that we believe can be achieved using this technology.
