Essay

Tri-State Manufacturing expects to spend $800,000 in 2016 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 $80,000 in fixed appraisal costs and variable costs of $0.40 per unit of finished product.The new method involves $120,000 in training costs and an additional $160,000 in annual equipment rental.It takes two units of material for each finished product.
Internal failure costs average $160 per failed unit of finished goods.During 2011,5% 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.
Required:
a.What is the net effect on appraisal costs for 2016,assuming the new receiving method is implemented and that 800,000 material units are received?
b.How much will internal failure costs change,assuming 800,000 units of materials are received and that the new receiving method reduces the amount of UNACCEPTABLE product units in the manufacturing process by 10%?
