Former Reasoner Bill Eggers teamed up with former Indianapolis mayor Steve Goldsmith to write a great new book--Governing by Network: The New Shape of the Public Sector.
Top-down government is losing its predominance as the primary method to deliver public services and fulfill public policy goals in America. Emerging in its place is a fundamentally different approach, in which government executives are redefining their core responsibilities away from managing government workers and programs to orchestrating both independent and public organizations to deliver services.
This new model, which the authors call "governing by network," is characterized by the web of relationships and partnerships that increasingly constitutes modern governance.
