ABSTRACTThis paper examines three distinct images of the policy process. Iron triangles emphasiże stable relations among a limited number of participants in a relatively closed policy area. Issue networks are fragmented, open and extraordinarily complex and are ill-structured for resolving conflicts and reaching authoritative decisions. The neo-corporatist literature posits a mechanistic interpretation of society: hierarchy, discipline, command and stability, though organized through sectors. These three images can be contrasted with an image of cabinet government which stresses the integrative capacities of central government. The United States can be seen to have moved to some degree from a pattern more closely captured by the iron triangle image to a looser, more complex one resembling features of the issue network image. In Britain, it is possible to detect some movement towards the complexity of the issue network approach. Despite some superficial plausibility, the corporatist image does not apply to Britain, which is best described by drawing on elements of the iron triangle and cabinet government images and some of the complexity of the issue network image. Finally, limits to the fragmentation implied by the issue network image are noted.
