The notable public administration scholar, Luther Gulick, offered a critique of metropolitan governance in the US that provides a framework to assess and critique how public administration has contributed to research about metropolitan governance. After reviewing the context for collaborative local governance in the US, this chapter uses Gulick’s three-part critique to assess what we know about the role of the public administrator in metropolitan America. Many studies have illuminated metropolitan and interlocal cooperation for service delivery. So too, public administration research has documented the institutional design challenges associated with metropolitan-wide planning efforts and the development of community goals. New investments should be made in exploring the individual-level underpinnings of metropolitan governance, or what Gulick labeled teamwork machinery. The chapter concludes with questions to guide future research and data development in each of these three areas.
