This chapter examines current theorizing and research on interorganizational network change, and considers its antecedents, processes, outcomes, and management. We perform a systematic review of this literature across several disciplines, including communication, management, organization studies, public administration, and technology studies. Combining the frameworks laid out by Kilduff and Tsai (2003) and Van de Ven and Poole (1995), we demonstrate that the process of goal-directed and serendipitous network change operates using different mechanisms. We highlight the dominant theories and research trends for both types of networks, then we conclude the chapter with a critique and offer four prescriptions for future research.
