a line of motorbikes and dirt bikes Underthe aue Ellington Company manufactures name CrossCountry. The company has been in business for almost 20 years and has maintained a profitable share of the recreational vehicle market due to its reputation for high-quality products. In addition, Ellington's engineering department has kept the company in the forefront by incorporating the latest technology in the CrossCountry bikes. Most subassembly work for the bikes is subcontracted to reliable vendors. However, the final assembly and inspection of all products is performed at Ellington's plant Ellington recently developed a new braking system for the CrossCountry Model 500 dirt bike. Because of the company's current availability of production capacity, Jim Walsh, production manager, recommended that the first lot of the new braking system be manufactured in-house rather than by subcontractors. This 60-unit production run has now been completed. The cumulative average labor hours per unit for the braking system was 60 hours. Ellington's experience with similar products indicates that a learning curve of 80% is applicable and that the learning factor can be expected to extend only through the fourth production run (60 per batch) for a total of 240 units Ellington's direct labor cost is $17 per direct labor hour Its management must decide whether to continue producing the braking system in its own plant or to subcontract this work.
