1940s

The separation of politics and administration advocated by Wilson continues to play a significant role in public administration today. However, the dominance of this dichotomy was challenged by second-generation scholars, beginning in the 1940s. Luther Gulick 's fact-value dichotomy was a key contender for Wilson's proposed politics-administration dichotomy. In place of Wilson's first generation split, Gulick advocated a "seamless web of discretion and interaction".

Luther Gulick and Lyndall Urwick are two second-generation scholars. Gulick, Urwick, and the new generation of administrators built on the work of contemporary behavioral, administrative, and organizational scholars including Henri Fayol, Fredrick Winslow Taylor, Paul Appleby, Frank Goodnow, and Willam Willoughby. The new generation of organizational theories no longer relied upon logical assumptions and generalizations about human nature like classical and enlightened theorists.

Gulick developed a comprehensive, generic theory of organization that emphasized the scientific method, efficiency, professionalism, structural reform, and executive control. Gulick summarized the duties of administrators with an acronym; POSDCORB, which stands for planning, organizing, staffing, directing, coordinating, reporting, and budgeting. Fayol developed a systematic, 14-point treatment of private management. Second-generation theorists drew upon private management practices for administrative sciences. A single, generic management theory bleeding the borders between the private and the public sector was thought to be possible. With the general theory, the administrative theory could be focused on governmental organizations. The mid-1940s theorists challenged Wilson and Gulick. The politics-administration dichotomy remained the center of criticism.
