Answer:
From a cost savings perspective the switch should be made in-house
Explanation:
In deciding whether Cool Systems should make or buy the switch , we calculate the relevant applicable to both situations,then compare t see which option saves costs.
The cost of making the switch is calculated thus:
Direct materials per unit $5
Direct labor $3
Variable overhead <u>$6</u>
Total relevant cost <u> $14</u>
The cost of purchasing the switch from another supplier is $15
From the above analysis, it is preferable to make the switch in-house as that option saves $1($15-$14) per switch.
However, it might be that we need to look beyond cost savings sometimes,purchasing the switch from another supplier might be viable if the quality of the outside switch is better or that the outside supplier can deliver in timely fashion.
