This paper examines Dialogue as a managerial fashion that has emerged since the early 1990s. While the early parts of the paper rely on well-tried approaches to and arguments about the phenomenon, the middle part of the paper attempts to define dialogue as a fashion, and offers a discussion of the dynamics of fashion-setting. Finally, we attempt to extend the theoretical framework by paying particular attention to the synchronic and diachronic dimension of a management fashion.div_MCaPAunpub2923unpu
