8. © M. RauterbergTechnical University of Eindhoven8/20 What is User-Centered Design?...based on expertise: –state-of-the-art knowledge for the design –linear product life cycle...based on participation: –multidisciplinary teams including end-user involvement in design and evaluation –iterative cyclic product life cycle “PUSH approach” “PULL approach”
