In this chapter, the authors critique dominant technocratic conceptions of rigor in management research and elaborate an alternative account of rigor that is rooted in methodology and involves a concern with the quality of scientific reasoning rather than a narrower focus on methods or measurement issues per se. Based on the proposed redefinition, the authors conceptualize how rigor, as an essential quality of reasoning, may be defined and the authors in turn qualify alternative methodological criteria for how they might assess the rigor of any particular piece of research. In short, with this chapter the authors’ overall aim is to shift the basis of rigor to an altogether more legitimate and commensurable notion that squarely puts the focus on reasoning and scientific inference for quantitative and qualitative research alike. The authors highlight some of the benefits that such an alternative and unified view of rigor may potentially provide toward fostering the quality and progress of management research.
