The document discusses formal and informal organization structures. It defines formal organization as having a predefined hierarchy, policies, and procedures. Features include job specialization and division of work. Benefits are clear objectives and communication. Limitations include loss of initiative. Informal organization arises from social needs and has no set structure. It promotes communication and creativity but can cause role conflicts. The contingency theory states an organization's structure depends on factors like the environment and people. Both formal and informal structures should be integrated to reduce conflicts and use informal channels for information sharing.
