An organizational structure is a framework that defines how certain tasks are directed in order to fulfill an organization's goals. These actions may involve the implementation of rules, roles, and duties. The organizational structure also governs how information moves inside the corporation. In a centralized structure, for example, decisions are made from the top down, but in a decentralized structure, decision-making authority is divided across several levels of the organization. Companies that have an organizational structure in place are more efficient and focused.
