Abstract
This research investigates the relationship between a sociomaterial ensemble and the performativity of organizational routines. While the role of materials has recently become a more central focus of organizational routine studies, many questions on the material-turn remain unanswered. Based on the debates of sociomateriality, we clarify how physical structure causes organizational routines to be executed. A comparative analysis of sports training organizations illustrated that more structured uses of artifacts helps organizations to perform their routines both materially and socially. We argue that coaches play an important role as modelers who create organizational physical models of sports organizations.
