In response to the ongoing debate in industrial network (IMP) literature regarding the manageability of networks, the present paper explores how a critical realist epistemology can facilitate a more multilayered explanation of collective change. In line with recent literature, we combine IMP with neo-institutional theory and identify the cognitive and normative boundary conditions for unmanaged change in networks. As such, we make a mid-range contribution to IMP by delineating structural antecedents of its interface with institutional entrepreneurship in explaining collective change in networks. The mechanisms underlying the transition from emergent to intentional change are illustrated with a case study describing difficulties experienced by Dutch steel wholesalers in realigning their business strategy with market conditions even when it is necessitated by upstream and downstream pressures. This paper is one of few examples of critical realist case-study research to guide scholars on how to translat this epistemological orientation into methodological choices
