Answer:
The production departments in the first stage and the unit of product in the second stage.
Step-by-step explanation:
Managerial accounting also known as cost accounting is an accounting technique focused on identification, measurement, analyzing, interpretation, and communication of financial information to managers for better decisions making and pursuit of the organization's goals.
This ultimately implies that, managerial accounting is specific to a particular business organization i.e the managerial accounting model used by a company would be different from the one used by another.
In Managerial accounting, the departmental overhead rate method is an accounting technique used for calculating the expense rate for each department in the manufacturing (production) process of a factory. Thus, it is solely based on breaking up overhead costs for each department rather than a factory-wide rate. The unit of activities in each segment of a business firm or factory determines the departmental overhead rate.
Generally, the cost object of the departmental overhead rate method is the production departments in the first stage and the unit of product in the second stage.
