This document discusses formal and informal organization structures within companies. It defines organization as identifying work, delegating responsibilities, and establishing relationships to accomplish objectives effectively. Formal organization refers to well-defined jobs and authority, providing stability but possibly delaying action and ignoring social needs. Informal organization comprises personal relationships that spontaneously develop based on feelings, filling gaps and spreading rumors but potentially hindering goals. Both organization types are important for a company to operate systematically depending on its nature and maturity.
