Lower level management, also known as supervisory or operational management, is the lowest tier of the managerial hierarchy. It consists of managers who oversee the work of employees and report to middle level managers. Lower level managers can make use of the managerial hierarchy to obtain approvals or additional guidance from their superiors when they face problems or challenges that are beyond their authority or expertise. The managerial hierarchy also helps lower level managers to communicate and coordinate with other managers and departments within the organization. References: 3, CITM Study Guide, Chapter 2: Organizational Structure and Design, Section 2.1: Types of Organizational Structures, Page 18.
