Abstract: This Thesis is a Computer Science approach towards the 'Design in 7 Days' vision. It describes a joint research project between the Department of Computer Science at the University of Copenhagen, Odense Steel Shipyard Ltd. and the Danish Maritime Institute. The research project is part of the research done by the Center for Object Technology. Important conclusions made during the work with the project are: (1) technology transfer between universities and private companies is possible with benefits for all, (2) evolutionary prototyping is a powerful strategy when requirements are not well-defined and new ways of supporting an engineering process is to be developed, (3) object oriented methods are well-suited for domain modelling, and (4) domain experts and IT experts in cooperation performs a strong team when systems supporting an engineering process is to be developed.
