The purpose of this article is threefold. First, it aims to delineate the flow of resources and the claims on those resources within the humanitarian aid system by locating task structures and functional units across the aid chain. Second, it draws on this account to highlight tensions in the system. Different stations in the organisational process are conditioned by the tasks assigned to them, how those tasks are anchored in a moral economy, and their historical interrelations. Third, it explores how aid organisations are perceived by experts in different parts of the aid chain. Four key agents were invited to recount their work experiences. We then consider how the outlook of the interviewees was shaped by their place in the aid chain. The interviews are an inventory of experiences, a preliminary corroboration of the organisational analysis that preceded them, and a source of future hypotheses. © 2015 The Author(s).
