This paper presents the findings from a systematic literature review of affordance theory research in the information systems field. 71 articles from the top eight information system journals were analysed, from the first publication in 1999 until March 2021. The analysis combines quantitative trends with qualitative analysis of the application of the concept of affordances. Significant findings include that half of the reviewed articles label technology use, features and attributes as affordances, although Gibson proposed that the term should be a non-replaceable term. The main contribution of this paper is a proposal of a tentative IS-flavoured definition of affordances, distancing itself from the possibility of labelling technology use as affordances. I conclude the analysis by stressing the importance of a common understanding of affordances in order to move forward in affordance research in the information systems field.
