This guide is designed for program officers to use in their work related to networks, coalitions, and other relationship-based structures as part of their initiatives, program strategies, and outcomes. It offers a set of core components that make up the basics of strategizing, implementing, and sustaining inter-organizational relationships and structures. You can work through the guide from beginning to end or jump to specific issues with which you might be struggling. Every component suggests concrete “actions” or questions that a program officer can apply.
