This article provides an overview of the key research findings and core concepts on the topic of organizational networks. The primary focus is on goal-directed “whole” service delivery networks, which are prevalent in the public and nonprofit sectors. The findings and ideas presented are especially salient for helping public managers build, maintain, operate, and govern multiorganizational networks in ways that will enhance their effectiveness. Because research and theory on networks extend well beyond the boundaries of public management and administration, the authors draw on thinking from a number of fields, providing a broad understanding of public networks and network functioning. The article is intended to provide usable information on networks for both practitioners and students, as well as to suggest directions for future research for the many public management scholars who now study organizational networks.
