Hauser Company, a family-owned business, engineers and manufactures a line of mopeds and dirt bikes under the trade-name Trailite. 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, Hauser's engineering department has kept the company in the forefront by incorporating the latest technology in the Trailite bikes. Most subassembly work for the bikes is subcontracted to reliable vendors. However, the final assembly and inspection of all products is performed at Hauser's plant. Hauser recently developed a new braking system for the Trailite 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 80-unit production run has now been completed. The cumulative average labor-hours per unit for the braking system was 60 hours. Hauser's experience with similar products indicates that a learning curve of 80 percent is applicable and that the learning factor can be expected to extend only through the fourth production run (80 per batch) for a total of 320 units. Hauser's direct labor cost is $14.50 per direct labor-hour. Its management must decide whether to continue producing the braking system in its own plant or to subcontract this work. Joyce Lane, Hauser's purchasing agent, has received a proposal from MACQ, a company specializing in component assembly. MACQ has done work in the past for Hauser and has proved to be of high quality and reliable. The terms of MACQ's proposal are negotiable, and before beginning discussions with them, Joyce has decided to conduct some relevant financial analysis.

 

Assumed learning curve =			80%		Therefore, the production time will likely follow
the following schedule:
Direct labor cost/hour =			$14.50
Batch size (units) =			80
80% Learning Curve
Cumul Output	Average Time	Total Time	Increase in Time	Time Per Unit
80	60.00	4,800	4,800	60.00
160	48.00	7,680	2,880	36.00
320	38.40	12,288	4,608	28.80

Required

1. Hauser Company has an immediate requirement for a total of 1,000 units of the braking system. Determine Hauser's future direct labor costs to produce the required braking system units if it manufactures the units in-house.

2. A consultant has advised Joyce that the learning rate for this application might be closer to 75 percent.

What is the effect on projected costs of using a 75 percent learning curve as opposed to an 80 percent learning curve?

3. What conditions in a manufacturing plant, if present, would offset the potential benefits of the learning curve? What is the strategic role of learning curve analysis for Hauser Company?
