Using longitudinal qualitative and network data capturing five years of evolution of an interorganizational network, this paper explores network orchestration -the process of assembling and developing an interorganizational network. In particular, we analyze shifts in the network orchestrator's actions and the network's structure and composition. We find that an orchestrator builds the capacity to assemble a network over time through the accumulation of resources and specialized expertise. However, as the network develops, an orchestrator faces an evolving set of dilemmas arising from the need to demonstrate value for various members and audiences. To resolve these dilemmas, orchestrators may shift their actions, moving from initially encouraging serendipitous encounters between network members ("blind dates") to increasingly selecting members and more closely influencing their interactions ("arranging marriages"). We discuss implications of our findings for a processual understanding of orchestrated network assembly and growth.

Industrial symbiosis (IS) is a collaborative environmental action whereby firms share or exchange by-products, materials, energy, or waste as a way to economically reduce aggregate environmental impact. Research in IS has flourished over the past two decades, and the time is ripe for a coherent review of organizational perspectives on the topic, particularly since the practice of IS is rife with difficulties often attributed to “social” factors. We review the organizational perspectives found in IS literature using a two-dimensional framework considering the antecedents, consequences, lubricants, and limiters of IS assessed through institutional, network/system, organizational, and individual levels of analysis. Our framework highlights what organizational perspectives have been adopted so far and also points to avenues of future scholarship of this unique phenomenon.

Summary While much work has been done on the conditions surrounding the emergence and establishment of industrial symbiosis (IS), new attention is being paid to understanding the evolution of IS over time. We demonstrate empirically how a new, facilitated IS initiative developed and evolved over an 8‐year period. We explore its network evolution by considering how the facilitator's actions enabled and precluded two fundamental network processes—serendipitous and goal‐directed processes. We discuss implications for a more generalized theory of IS development by exploring why and how different evolutionary trajectories may unfold.

The engagement of firms in environmental collaborations has become a ubiquitous phenomenon in today’s business landscape. Yet much of the research to date is fragmented across multiple disciplines and lacks a clear framework to support future study. The authors consolidate and synthesize existing contributions into a conceptual map comprised of antecedents, consequences, and contingencies to better understand environmental collaborations. This map offers a perspective on how firms develop strategies, structures, and capabilities to manage and balance environmental and economic performance and increasing demands for environmental sustainability from multiple stakeholders and society. The authors then highlight existing gaps in the extant literature and outline a future research agenda, including key questions and issues needing additional study.
