This document discusses different types of organizational structures. Line and staff organization combines elements of a line organization, where authority flows vertically from top to bottom, and a staff organization, where specialists provide advice and services. In a line and staff organization, line officers have authority to make decisions and direct workers, while staff officers are experts who advise line officers. There can be conflicts as line officers are responsible for results but may neglect staff advice, while staff focus only on their departments instead of organization-wide goals.
