A general principle of performance evaluation is that managers should not be held responsible for

costs or activities over which they have no control.

The three methods for allocating service department costs to producing departments are:

The Direct Method

The Sequential Method

The Reciprocal Method

Departmental Overhead Rates

The overhead rate for the grinding department is computed as follows (assuming the normal level of activity is 71,000 MH):

OH rate = $355,000 71,000 = $5 per MH

The overhead rate for the assembly department is computed as follows (assuming the normal level of activity is 107,500 DLH):

OH rate = $215,000 107,500 = $2 per DLH
