Ways of Drifting: 5 Methods of Experimentation in Research through Design

Design experiments are claimed to be a core means of inquiry in the research tradition of research-through-design. However, it is rarely articulated how the experiments were carried out in order to test a hypothesis, to begin a fruitful journey into unexplored design terrain or just gradually build knowledge. On the basis of the analysis of ten PhD theses we provide a typology comprised of five forms of design experiments in research-through-design. This provides a general outline of the characteristics which point to the methodological roles that design experiments and design work may acquire in research-through-design.
Our typology of design experiments in research-through-design accounts both for relations between major cases and iterations embodied in detailed sketches and prototypes. The purpose of the typology is to provide an overview that respects and account for the less-than-ideal way design research actually happens: process-loops where hypothesis, experiments, and insights concurrently affect one another and result in a drift of research focus and continued adjustment of experiments to stabilize the research endeavour.
