RGT is a technique for eliciting and evaluating people’s subjective experiences of interacting with technology, through the individual way they construe the meanings of members of the set of artifacts under investigations. It thus attempts to capture how users experience things, what the experience means for them, and covers both emotionally- based constructs (warm-cold) and more
First, an individual participating in an elicitation session produces his or her own constructs, i.e. what bipolar dimensions of meaning the person see as the most important ones for talking about the elements (the investigated phenomena). The construct elicitation process is typically eased by the use of triads, where the subject becomes exposed to sets of three elements at a time and is asked to describe and put a label on what he or she sees as separating one of the elements in the group from the other two. Second, after having provided their own individual, qualitative constructs, the participant is asked to rate the degree to which each element in the study relates to each bipolar construct according to some scale (typically a binary or Likert-type scale). Constructs and elements are the two building blocks of each individual’s own repertory grid table; which are quantitatively related to each other by use of some rating system.
The Repertory Grid Technique (RGT) is an open and dynamic technique for eliciting people’s experiences and meanings in relation to technological artifacts, while it at the same time providing for modern methods of statistical analysis. The RGT is best understood as a technique on the border between qualitative and quantitative research methods.
One disadvantage of RGT is that it requires a substantial amount of effort to be
invested both by the experimenter/designer and by the participants at the time of
construct elicitation, as compared to many quantitative methods. On the other
hand, RGT is in some ways more efficient and less time-consuming than most fully
open approaches, e.g. unstructured interviews and explorative ethnography.
