Outsourcing (Make-or-Buy) Decision Mountain Air Limited manufactures a line of room air purifiers. Management is currently evaluating the possible production of an air purifier for automobiles. Based on an annual volume of 10,000 units, the predicted cost per unit of an auto air purifier follows.

Direct materials $ 9.00

Direct labor 1.40

Factory overhead 10.00

Total $ 20.40

These cost predictions include $80,000 in fixed factory overhead averaged over 10,000 units. The completed air purifier units include a battery-operated electric motor, which Mountain Air assembles with parts purchased from an outside vendor for $2.00 per motor. Mini Motor Company has offered to supply an assembled battery-operated motor at a cost of $5.50 per unit, with a minimum annual order of 5,000 units. If Mountain Air accepts this offer, it will be able to reduce the variable labor and variable overhead costs of the auto air purifier by 50 percent.

(c) What additional factors should it consider in deciding whether to make or outsource the electric motors? The quality of their own and the supplier's motors. The dependability of the supplier. Whether Mini Motor has a track record of meeting its commitments. Whether they can depend on Mini Motor to supply motors for a number of years or whether it is attempting to use some temporarily idle capacity. All of these.
