The current study explores the role of stories in organizational sensemaking processes. Rather than positioning stories as one among many different sensemaking mechanisms, it is argued that stories allow a particular kind of sensemaking that is inherently openended, distinguishing it from theoretical and propositional explanations for organizational phenomena. Drawing on previous Foucaultian discussions of epistemes, I introduce the notions of epistemic impasse and epistemic spillover, arguing that cross-functional interaction can cause tensions between incompatible epistemic bases, and that stories can act as a mechanism to overcome such tensions. I illustrate this mechanism in an ethnographic, participant-observer study of a university student-support center, showing how storytelling led to an increasingly open although ultimately totalizing tendency within the center, thus demonstrating both the potentials and limits of using stories within organizations.
