The benefits of involving users in a development process are well described. This paper describes a procedure for using 2D and 3D models in a workplace design process, which is based on three rounds of user studies within the maritime domain. The process includes various kinds of models that can be used in order to elicit design feedback in a cost-effective manner. Design teams can greatly benefit from using such mediating objects to draw out the users’ previous experiences. It was found that different model types allow different levels of reflection and questioning of the design from the prospective users.
