How Tangible Mock-Ups Support Design Collaboration

This paper is a contribution to a more conscious use of tangible mock-ups in collaborative design processes. It describes a design team’s use of mock-ups in a series of workshops involving potential customers and users. Focus is primarily on the use of three-dimensional design mock-ups and how differences in these affected the dialogue. Reflective conversations were established by using tangible mock-ups as “things-to-think with.” They served as boundary objects that spanned the gap between the different competencies and interests of participants in design. The design mock-ups evoked different things for different participants, whereas the challenge for the design team was to find boundaries upon which everybody could agree. The level of details represented in a mock-up affected the communication so that a mock-up with few details evoked different issues, whereas a very detailed mock-up evoked a smaller variation of issues resulting in a more focused communication.
