ABSTRACT
In the previous chapters, our focus was on planning and conducting design research case studies, whereas in this chapter we look at the best practices of evaluating, analyzing, and interpreting the data coming out of the process. We investigate these procedures from an interdisciplinary perspective by applying the principles of integrative data evaluation, or the “Four Pillars and the Roof,” as Pauwels and Matthyssens have termed it. Especially regarding convincing communication of research outcome to others, we also discuss the means of logical argumentation, including the three primary characteristics of that kind of conceptual, systematic constructions, that is, definitions, relations, and rhetorics, as they apply to case study methodology. Finally, we discuss some of the recent paradigm shifts in design research, including not only practice-based research, but also the rather new practice-based PhD degree also discussed in the Epilogue.
