This type of differentiation describes the differences among workers or units in an organization. This may include their education, type of training, and the tasks assigned to them. Since pharmacies concentrate not only on providing pharmacy services but also on merchandising non pharmacy-related items, all employees must be oriented on offering such services and items to the consumers. If all personnel had the same training, managing the organization would be easier because everyone would have a similar orientation. This is not the case in a pharmacy since the coordination of work among employees and personnel in the different units can be more difficult. may also refer to the multi-ownership of different firms from a variety of related industries. For example, a health system can own several firms with different functions such as hospitals, health care and nursing facilities, and managed-care businesses.
