13-30 STRATEGIC ANALYSIS OF OPERATING INCOME. Dransfield Company manufactures an electronic component, ZP98. This component is significantly less expensive than similar products sold by Dransfield's competitors. Order-processing time is very short; however, approximately 10% of products are defective and returned by the customer. Returns and refunds are handled promptly. Yorunt Manufacturing, Dransfield's main competitor, has a higher-priced product with almost no defects but a longer order-processing time. Assume that in 2019, Dransfield has changed its processes and trained workers to recognize quality problems and fix them before products are finished and shipped to customers. Quality is now at an acceptable level. Cost per kilogram of materials is about the same as before, but conversion costs are higher, and Dransfield has raised its selling price in line with the market. Sales have increased and returns have decreased. Dransfield's managers attribute this to higher quality and a price that is still less than Yorunt's. Information about the current period (2019) and last period (2018) follows. LO 4 1. Change in operating income, $36,820 F
