Seeking to close the gap between expectations and capacity, presidents have utilized a broad interpretation of executive power to control administrative affairs. However, the emergence of a post–New Public Management environment characterized by loosely constructed networks and a surge of governmental activity has required an evolution in the tools needed to govern.

This dynamic potentially enables more effective and responsible execution of public laws.
