Divisional structure is used by large companies with multiple product lines or geographical locations. The organization is divided into autonomous business units, with each unit responsible for a specific product or customer segment. There are two main types of divisional structures: product divisionalization, where each division is responsible for a separate product line; and territorial divisionalization, where divisions are based on geographical regions. Divisional structures allow each business unit to operate independently while benefiting from centralized corporate resources and management oversight.
