PurposeThe purpose of this paper is to explore the role and implications of storytelling and narrative as a means of making sense of, and giving sense to, the ambiguous concept of materiality.Design/methodology/approachThe use of stories was “discovered” through the authors' attempts to “make sense” of data from 16 interviews with participants from the financial and nonfinancial reporting and assurance contexts. The authors analyse the participants' use of stories through a sensemaking/sensegiving lens.FindingsWhile participants struggle to define what materiality is, they are able to tell “stories” about materiality in action. The authors find stories are a key vehicle through which participants make sense of and give sense to materiality, for themselves and (an)other. Participants tell three types of stories in sensemaking/sensegiving processes: the lived, the adopted and the hypothetical. The authors further identify “rehearsed” and “ongoing” narratives, which take any of the three story types. The use of stories to make and give sense to materiality reveals a disconnect between the static, technical definitions of materiality currently favoured by standard setters and guidance providers, and the creative authoring processes the participants employ.Practical implicationsThe authors argue for a move towards the use of stories and narratives about materiality in standard setting, specifically “materiality in action”, which the findings suggest may assist in creating shared understandings of the ambiguous concept.Originality/valueWhile previous research considers what materiality means within financial and nonfinancial reporting and assurance contexts, the authors empirically analyse how people understand and make sense/give sense to materiality. The authors also contribute to the use of sensemaking/sensegiving processes within the accounting literature.
