Number of finished units*

4.50

*Refers to number of units receiving the finishing activity, not the number of units transferred to Finished Goods Inventory

Oscar produced two styles of bookcases in October: the standard bookcase and an unfinished bookcase, which has fewer parts and requires no finishing. The totals for quantities, direct materials costs, and other data follow:

2. Suppose that pre-manufacturing activities, such as product design, were assigned to the standard bookcases at \(5 each and to the unfinished bookcases at \)3 each. Similar analyses were conducted of post-manufacturing activities such as distribution, marketing, and customer service. The post-manufacturing costs were \(20 per standard bookcase and \)18 per unfinished bookcase. Compute the full product costs per unit.

Short Answer

Expert verified

Answer

Full product cost per unit

For standard bookcase: $87

For unfinished bookcase: $61.93

Step by step solution

01

Computation of full product cost for standard bookcase

Manufacturing cost for standard bookcase computed in earlier part: $434,000

Productdesigncost=Costperunits×No.ofunitsproduced=$5×$7000=$35,000Analysiscost=Costperunits×No.ofunitsproduced=$20×$7000=$140000Totalfullproductioncost=Manufacturingcost+Productiondesigncost+Analysiscost=$434,000+$35,000+$140,000=$609,000Fullproductiocostperunit=TotalfullproductioncostNo.ofunitsproduced=$609,000$7000=$87

02

Computation of full product cost for unfinished bookcase

Manufacturing cost for unfinished bookcase computed in earlier part: $307,000

Productdesigncost=Costperunits×No.ofunitsproduced=$3×$7000=$22,500Analysiscost=Costperunits×No.ofunitsproduced=$18×$7500=$135000Totalfullproductioncost=Manufacturingcost+Productiondesigncost+Analysiscost=$307,000+$25,000+$135,000=$464,000Fullproductiocostperunit=TotalfullproductioncostNo.ofunitsproduced=$464,000$7500=$61.93

Question:Stella, Inc. is using a costs-of-quality approach to evaluate design engineering efforts for a new skateboard. Stella’s senior managers expect the engineering work to reduce appraisal, internal failure, and external failure activities. The predicted reductions in activities over the two-year life of the skateboards follow. Also shown are the predetermined overhead allocation rates for each activity.

Activity Predicted Predetermined

Reduction in Overhead Allocation

Activity Units Rate per Unit

Inspection of incoming raw materials 390 $ 44

Inspection of finished goods 390 19

Number of defective units discovered in-house 1,200 50

Number of defective units discovered by customers 325 72

Lost profits due to dissatisfied customers 75 102

Requirements

1. Calculate the predicted quality cost savings from the design engineering work.

What are quality improvement programs?

The Alexander Manufacturing Company in Rochester, Minnesota, assembles and tests electronic components used in smartphones. Consider the following data regarding component T24 (amounts are per unit):

2. Why might managers favor this ABC system instead of Alexander’s older system, which allocated all manufacturing overhead costs on the basis of direct labor hours?

Question:Blanchette Plant Service completed a special landscaping job for Kerry Company. Blanchette uses ABC and has the following predetermined overhead allocation rates:

Activity Predetermined

Allocation Base Overhead Allocation Rate

Designing Number of designs \( 290 per design

Planting Number of plants \) 20 per plant

The Kerry job included \(750 in plants; \)1,300 in direct labor; one design; and 30 plants.

Requirements

3. If Blanchette desires an operating income of 30% of cost, how much should the company charge for the Kerry job?

List and define the four types of quality costs.
