This chapter explores what different researchers have been calling for recently: the inclusion of materiality in investigations, and in conceptualizations, of leadership. It identifies leadership as what directed, shaped, and ordered the project's unfolding. The chapter offers a detailed illustration of one such instance of leadership's hybrid production. It suggests seeing leadership as a set of practices that have organizing effects, and therefore conceptualizes leadership as a consequence of collective action, not as one of its causes. The chapter suggests conceptualizing leadership as one of the products of collective action, as the consequence of social practices accomplished through interactions involving various actants, and as happening via processes constantly in movement. The communicational nature of practices is rarely acknowledged in the practice perspective, while it is clear that interactions and practices happen through communication. Finally, the chapter touches on the vast topic of materiality, and the chosen vignette mobilized one specific category of materiality: documents.
