A mechanistic structure is an organizational design characterized by a high degree of formalization and centralization. In this type of structure, roles and responsibilities are clearly defined, and communication typically flows in a top-down manner. This design is often found in large organizations or industries that require strict adherence to rules and procedures, such as manufacturing or government agencies. In a mechanistic structure, decision-making authority is concentrated at the top levels of management, which can lead to efficient operations but may also stifle creativity and flexibility. Employees usually have specialized roles, and tasks are performed in a predictable and standardized way, making it easier to manage large teams and complex processes.
