Organizational structure refers to how tasks and responsibilities are allocated within an organization. It is represented visually in an organizational chart. Organizational design is the process of coordinating these structural elements based on factors like the environment, technology, strategy, and human resources. Key design decisions include the division of labor, departmentalization approach, span of control, and level of authority. Organizations differentiate horizontally by specialization, vertically by hierarchy, and spatially by geographic dispersion. Integration coordinates the differentiated parts through vertical methods like rules and committees or horizontal methods like liaison roles and teams. Common organizational structures include machine bureaucracies, professional bureaucracies, divisional forms, and adhocracies.
