Question
Chapter 7.S, Problem 8DRQ
Summary Introduction
To determine: The factors that might cause the learning curve to tip up towards the end of a job.
Introduction: Learning curve is referred as the cost curve, experience curve, efficiency curve or productivity curve. The learning curve gives information about the cost, efficiency, productivity and performance of an organization.
In general learning curve gives the relationship between the cost and output generated for a period of time. Learning curve represents the repetitive tasks of an employer or a worker.

Manceville Air has just produced the first unit of a large industrial compressor that incorporated new technology in
the control circuits and a new internal venting system. The first unit took 112 hours of labor to manufacture. The
company knows from past experience that this labor content will decrease significantly as more units are produced.
In reviewing past production data, it appears that the company has experienced a 85% learning curve when producing
similar designs. The company is interested in estimating the total time to complete the next 7 units.
Your job as the production cost estimator is to prepare the estimate. Refer to Table E.3.
