This document discusses span of control, which refers to the number of subordinates a manager can effectively oversee. There are two types of span: narrow span involves a manager overseeing 2-3 subordinates and offers tight control but creates more management levels, while wide span involves a manager overseeing 7-8 subordinates and saves time but reduces performance quality. An effective span of control leads to better supervision, increased efficiency, good communication, and developed trust and discipline. The factors that affect span of control include the nature of work, trust in subordinates, fixation of responsibilities, and the capacities of both the supervisor and subordinates.
