<P> Divisional structures are also called' product structures' because they are based on a certain product or project . This structure is most common in multi-service organizations . Normally, it's based on the departments divided in the firm . </P> <P> Geographic structures are used in multi-site organizations and are frequently used by networks across different geographic areas . </P> <P> The Matrix structure is probably the most complicated model of them all because it is organised around multiple dimensions (e.g. geography and product), typically with more than one supervisor . This structure is commonly used in very large organisations because a greater volume requires greater co-ordination . However, this structure is very difficult to manage so it is usually better to reconsider its use and replace it with a different type of structure, then compensate for the tradeoffs . </P> <P> In addition to those models, there are other factors that make up the structure of an organization . Depending on the chain of command, a company's structure could be classified as either vertical or horizontal, as well as centralized or decentralized . A vertically structured organization or a "tall" company describes a chain of management, usually with a CEO at the top delegating authority to lower - level managers through mid-level managers . Horizontal or "flat" companies, however, have almost no middle - managers, which implies that high - level managers get involved in daily tasks and interact with customers and front - line personnel . A centralized organizational structure describes how a company's direction and decisions are set by one individual only . Centralization compliments companies with "tall" structures to create Bureaucratic organizations . Decentralized organizational structures allow individuals some autonomy at each level of the business, because they join the decision - making process . Evidently, classifying organizations as centralized or decentralized is linked to them being "tall" or "flat". </P>
