Designers ' Role Orientations in User-and System-Centered Design Phases

The differences between userand system-centered design practice have been discussed broadly in the literature for a long period. The value of user-centredness has even been taken for granted occasionally, though there is clear evidence implying that broader participation of users should be evaluated relative to the situation in hand. In this paper, both userand system-centered conducting of a design is studied with respect to how to behave in different roles. The core idea is that userand system-centredness are needed in different phases of a design. The main problem is the proper role orientation in user-centered design. Change agentry models are used as a framework. As a result of this study, a proper role orientation in both system-centered and, especially, user-centered design is
