This paper theorizes on the sociotechnical dynamics and underlying dimensions of technology assemblages that emerge from the use of social technologies in organizations. This theorization reflects more precisely the information ecology around knowledge workers, which is more technologically diversified than suggested by prior studies. To that end, this work differs from the few studies of social technologies and many studies of ICT in organizations by focusing on more than one technology and by considering social technologies as an assemblage. In order to advance current theorizing about technology assemblages, this works draws on data from a study of knowledge workers’ use of social technologies for knowledge sharing and presents three complementary analytic lenses: Practice, Structural, and Interpretive. Integrating the three lenses, allows us to holistically capture the disparate dimensions of social technology assemblages enacted by knowledge workers.
