What is the difference between a Manager 3 and Manager 4?

Positions at the Manager 4 (M4) level serve as the senior manager overseeing a large organization with multiple departments. They identify objectives and direct critical programs with major constituencies across campus. Very few positions on campus meet the M4 criteria. In contrast, a M3 position leads a critical function on campus, typically managing multiple subordinate organizations with different levels of Managers 1 and 2, Supervisors, professionals and other staff.
