The document discusses centralization and decentralization of authority in organizations. Centralization refers to concentrating authority at higher levels of management where top managers make all decisions and lower levels simply follow directives. Decentralization means dispersing authority throughout the organization so that lower level employees can make decisions. Centralization allows for uniform policies but limits flexibility and creativity, while decentralization promotes initiative but relies on employee quality. The document also defines span of control as the number of subordinates reporting to a single manager, noting the optimal span depends on work complexity. Wider spans distribute management workload but narrower spans allow for closer supervision and attention to individual employees.
