A company wants to decide whether to make its materials in-house or whether to sub-contract production to an external supplier. In the past it has made four materials in-house, but demand in the next year will exceed in-house production capacity of 8,000 units. All four materials are made on the same machines and require the same machine time per unit: machine time is the limiting production factor. The following information is available. 



If a decision is made solely on the basis of short-term cost considerations, what materials should the company purchase externally? 

A

 4,000 units of W and 1,000 units of Z 

B

 4,000 units of W and 4,000 units of Z 

C

 3,000 units of Y and 2,000 units of Z 

D

1,000 units of Y and 4,000 units of Z

The correct answer is: 4,000 units of W and 4,000 units of Z. 


It would save $1,000 in cash to buy Material W externally. If full production can be achieved for the other materials, only W would be purchased externally. However, there is insufficient capacity to produce all three materials in-house. 

If in-house production of Material Z is reduced to 3,000 units, the additional cost of external purchase would be only $6,000, so that $1,000 would be saved by purchasing all of Z externally. 

The easiest way of understanding this is to look at the total costs associated with Product Z depending on which course of action is chosen:

 • Buy them all in ($12 × 4,000 units) = $48,000

 • Buy in 1,000 ($12 × 1,000) = $12,000 and make the remaining 3,000 ($10 × 3,000) + 7,000 specific fixed costs = $49,000 

Therefore it is best to buy in all 4,000 units despite having the capacity to make 3,000.
