11) Strykerz Corp expects to spend $800,000 in 2015 in appraisal costs if it does not
change its incoming materials inspection method. If it decides to implement a new
receiving method, it will save $60,000 in fixed appraisal costs and variable costs of
$0.50 per unit of finished product. The new method involves $140,000 in training costs
and an additional $150,000 in annual equipment rental.
Internal failure costs average $160 per failed unit of finished goods. During 2014, 5%
of all completed items had to be reworked. External failure costs average $400 per
failed unit. The company’s average external failures are 1% of units sold. The company
carries no ending inventories, because all jobs are on a per order basis and a just-in-time
inventory ordering method is used.
