Exam 7: Extension: Learning Curves

Unit times for a job exhibit a learning effect. If the second unit took 30 hours, and the fourth unit took 21 hours, roughly how many hours would you estimate the third unit took?

A job is expected to have a learning curve of 90 percent. The third unit required 16 hours. The 12^th unit should take approximately how many hours?

It takes a worker with a 90 percent learning curve 72.9 minutes to complete the fourth unit of a seven-unit job. Estimate the amount of time the worker spent on the first two units.

When the task is fairly complex and has a longer duration, it will take a larger number of repetitions before improvement is observed.

In which of the following scenarios would an 80 percent learning curve be especially relevant?

A manager is trying to estimate the learning rate for a new job. The first unit took 16 hours and the fourth unit required about 13 hours. The learning rate is:

A manager is trying to estimate the appropriate learning curve for a certain job. The manager notes that the first four units had a total time of 30 minutes. Which learning curve would yield approximately this result if the first unit took 10 minutes?

A company is preparing a bid on a government contract for 40 units of a certain product. The operations manager estimates the assembly time required for the first two units to be 10.4 hours and 8.8 hours respectively. What is the appropriate learning curve?
