Rhetorical Appeals of Professional Designers in Decision-Making Sessions

Erin Friess University of North Texas

Abstract

Research problem: No study has observed the argumentative choices and appeals used by professional designers to support their claims as they engage in decision-making sessions. In particular, we do not know how user-derived data are applied by professional designers in their decision-making arguments. Research questions: (1) What kinds of evidence and appeals do advocates of user-centered design use when supporting claims within design decision-making sessions? (2) How do evidence and appeals used by professional designers compare to evidence and appeals used by previously studied novice designers? Literature review: Previous research of user-centered design that also incorporates data-driven personas has concluded that while some observed groups dedicated to user-centered design see personas as a way to further improve upon user-centered design methods, personas rarely become an integrated part of the design process and are often not incorporated in recommended ways. Prior research of decision-making within the design process has concluded that decision-making is a highly variable, but often deeply collaborative activity that can be assessed through a variety of argumentative lenses, including the Toulmin model of argument. Methodology: In this case study, a one-week, onsite exploratory observation was conducted in the workplace of professional designers. All meetings were recorded and subsequently transcribed. Postobservation interviews were also conducted with the participants. A discourse-based analysis was conducted on the transcriptions to identify the various types of rhetorical appeals and evidence used by the designers during their decision-making meetings. Results and conclusions: This onsite observation found that this particular group of designers supported about 50% of their claims with evidence, with 5.1% of the evidence in support of a claim referencing user data, and 33.4% of evidence in support of a claim referencing the designer's own opinion. These results suggest, among other things, that personas (the key user-centered design tool used by the observed group) are perhaps not necessarily a helpful rhetorical tool for persuasion in decision-making meetings, that designers who conduct user research are more likely to reference user data in support of claims, that these designers might have a broad notion of what constitutes user data, and that prior experience can serve as a powerful persuasive force. In addition, appeals to user data were the least common type of appeal employed by the novice and professional designers. However, this exploratory study is limited by the condensed observation time and its single group of designers. Future studies may use the methodology established here to explore the uses of evidence of additional groups.
