As the world becomes more and more organized, it seems ever more difficult to find anyone responsible. Why is that? We argue that the extensive external organization of organizations in contemporary society provides the key. Formal organizations are collective orders with great potential for concentrating responsibility on top managers and the organization. But when they are organized by other organizations, this potential is undermined, and responsibility becomes diluted rather than concentrated. We explain this outcome by analysing the communication of decisions as a main producer of responsibility and by defining organization as a decided order. Our analysis draws upon and contributes to research about partial organization, but it also contributes to literatures on global governance and organizational institutionalism.
