A service department such as the Personnel Department or the Cafeteria must exist in order for an organization to carry out its primary function.
Therefore, the cost of running a service department is part of the cost incurred by the organization in producing goods or services.
In order to determine the cost of those goods or services, all service department costs must be allocated to the production departments in which the goods or services are produced. For this reason, the costs incurred in an automobile plant’s Maintenance Department are allocated to all of the production departments that have machinery.
The costs incurred in a hospital’s Human Resources Department are allocated to all of the departments that have personnel.
Direct-patient-care departments, such as Surgery and Physical Therapy, are allocated their share of the Human Resources Department’s costs.
The allocated costs become a portion of the factory overhead that is then applied to the cost of the finished product.
