A divisional structure is made up of separate divisions according to similarities or demands of product, customers, or geography. Each division has its own functional departments therefore, allowing managers to focus on the specific products sold by the company. However, it also more expensive as the company needs multiple sets of support functions. Therefore, some central support functions can be used to provide support services for all divisions. For example, Information Technology and Finance departments may be centralized at the top (headquarters) such that all business units can make use of those functions.
