In design research, the activities of design and research coalesce. It introduces thorny epistemological challenges and Dewey's pattern of inquiry is explored for its relevance for design research. First, a logical framework for design inquiry is developed that enables to reach warranted conclusions, retrospectively. Second, a temporal framework of activities is inferred, based on the experiences of two PhD candidates. These frameworks offer guidance to (1) develop transferable knowledge; (2) by oscillating between known theories and uncharted practices until new ideas arise; whereby (3) the value of these ideas is validated through experiments (action validity); and (4) with a community of inquiry (consensual validity). The knowledge produced stems from practice, is tested in practice and serves others in future inquiries.

This paper explores the social dimension of collaborative design from the perspective of Schön's reflective practice. An in-depth video protocol study was performed on the reflective practice in an experienced design team. It looks, in particular, at reframing: the process to find a new productive frame for subsequent activities. Reframing processes are amplified in a social context, requiring considerable time and effort on the part of design teams. Reframing has distinctive features that set it apart from other steps of reflective practice. Two iterative stages are discerned: sensemaking, to reconstruct prior operating frames; and future framing, to design a frame for future activities. Surprises incite reframing, and we argue that surprises are a source for team learning and innovation.
