This is a complete and up-to-date revision of the classic text for public administration which presented public administration as a tension between the necessary exercise of power and the search for accountability by public servants. In this revision, the authors have initiated a new approach to the study of public administration by focusing on middle- and lower-level managers. These are positions that most students will occupy for the bulk of their professional careers. The book recognizes that most of the administration is in field offices, in state and local government, and in cooperation with the private sector. It then focuses on power and its potential for influencing the behavior of the bureaucracy. This leads to the relationship between theories about administration and the actual practice.
