Relief efforts resulting from the $5 billion Priority Reconstruction Program, launched as part of the 1995 Dayton Peace Agreement, attracted nearly 500 nonprofit organizations to the small, newly independent nation of Bosnia. Donor resources and recipient needs changed over time forcing constant adjustment in this environment, at times resulting in service overlap, inefficiency, and waste. However, the inter-relatedness of tasks in this war-torn country continually reminded players of the need for cooperative, coordinated action. Within a short time, intricate webs of interorganizational relationships emerged among donors, NGO implementers, and host nation players, at both ground and global levels. The research reported here is based on extensive interview material with a diverse range of informants.
