15. 7 -15 Budgeted Versus Actual Usage When we allocate support- department costs to the producing departments, should we allocate actual or budgeted costs?

16. 7 -16 Budgeted Versus Actual Usage Budgeted costs.

17. 7 -17 Budgeted Versus Actual Usage A general principle of performance evaluation is that managers should not be held responsible for costs or activities over which they have no control.

20. 7 -20 Choosing A Service Department Cost Allocation Method The three methods for allocating service department costs to producing departments are:  The Direct Method  The Sequential Method  The Reciprocal Method

21. 7 -21 Support Departments Producing Departments Direct costs*$250,000$160,000$100,000$ 60,000 Normal activity: Kilowatt-hours-----200,000600,000200,000 Maintenance hours1,000-----4,5004,500 * For a producing department, direct costs refer only to overhead costs that are directly traceable to the department.
