The Tristan Corporation sells 250,000 V262 valves to the automobile and truck industry. Tristan has a capacity of 150,000 machine-hours and can produce two valves per machine-hour. V262's contribution margin per unit is 7. Tristan sells only 250,000 valves because 50,000 valves (20% of the good valves need to be reworked. It takes 1machine-hour to rework two valves, so 25,000 hours of capacity are used in the rework process. Tristan's rework costs are 550,000 dollar Rework costs consist of the following: Direct materials and direct rework labor (variable costs): 5 dollar per unit Fixed costs of equipment, rent, and overhead allocation: 6 dollar per unit Tristan's process designers have developed a modification that would maintain the speed of the process and ensure 100% quality and no rework. The new process would cost 538,000 dollar per year. The following additional information is available: The demand for Tristan's V262 valves is 400,000 per year. The Colton Corporation has asked Tristan to supply 27,000 T971 valves (another product) if Tristan implements the new design. The contribution margin per \(\mathrm{T} 971\) valve is \(\$ 12 .\) Tristan can make one \(\mathrm{T} 971\) valve per machine-hour with \(100 \%\) quality and no rework. 1\. Suppose Tristan's designers implement the new design. Should Tristan accept Colton's order for 27,000 T971 valves? Show your calculations. 2\. Should Tristan implement the new design? Show your calculations. 3\. What nonfinancial and qualitative factors should Tristan consider in deciding whether to implement the new design?
Safe Travel produces car seats for children from newborn to 2 years old. Safe Travel's only problem with its car seats was stitching in the straps. The problem can usually be detected and repaired during an internal inspection. Inspection costs 5.00 per car seat, and repairs cost 1.00 per car seat. All 200,000 car seats were inspected last year, and 5 \% were found to have problems with the stitching. Another 1% of the 200,000 car seats had problems with the stitching, but the internal inspection did not discover them. Defective units that were sold and shipped to customers are shipped back to Safe Travel and repaired. Shipping costs are 8.00per car seat, and repair costs are 1.00 per car seat. Negative publicity will result in a loss of future contribution margin of 100 for each external failure. 1\. Identify total costs of quality by category (appraisal, internal failure, and external failure). 2\. Safe Travel is concerned with the high up-front cost of inspecting all 200,000 units. It is considering an alternative internal inspection plan that will cost only 3.00 per car seat inspected. During the internal inspection, the alternative technique will detect only 3.5 \% of the 200,000 car seats that have stitching problems. The other 2.5% will be detected after the car seats are sold and shipped. What are the total costs of quality for the alternative technique? 3\. What factors other than cost should Safe Travel consider before changing inspection techniques?
'Companies should always make and sell all products whose selling prices exceed variable costs." Assuming fixed costs are irrelevant, do you agree? Explain.
Companies should focus on financial measures of quality because these are the only measures of quality that can be linked to bottom-line performance." Do you agree? Explain.
Distinguish between customer-response time and manufacturing cycle time.
