True

An assumption of learning curves is that the time required to complete a unit will decrease at a decreasing rate as the cumulative number of units completed increases.

Logarithms

Which of the following computational methods are used to calculate learning curve statistics?

$8,062.00

A company can produce a small lot of products the first time at a cost of $2,000. If their 85 percent learning curve allows them to reduce their costs on each lot, what is the total cost of producing 5 lots?

$466.20

A company can produce a small lot of products the first time at a cost of $3,000. If their 65 percent learning curve allows them to reduce their costs on each lot, what is the cost of producing the 20th lot?

By the 50th unit

A company's production process has an 85 percent learning curve rate. The process has produced 1,000 units to date. A process refinement is estimated to allow a future learning curve rate for the identical product of 75 percent. However, the initial unit made using the new process will take the same amount of time as the initial unit produced using the old process. At what point, using the new process, will the production rate exceed the production rate achieved by the old process?

True

A learning curve is a line displaying the relationship between unit production time and the cumulative number of units produced.

False

A learning curve shows the increase in time required for each successive unit completed.

47.66 minutes

The 10th repetition of job is timed at 100 minutes. If the learning curve for this job is 80 percent, what is the estimated time for the 100th repetition of this job?

Early removal of workers who do not improve

The general guidelines provided in the textbook on improving individual learning based on learning curves does not include which of the following?

4.542 minutes T25 = T1 * UIF60%/25 = 5 minutes * 0.0933

The unit improvement factor for an 80 percent learning curve at 100 units is 0.2271. The first and second timings of a person doing a job are 20 minutes and 16 minutes, respectively. What is the learning-adjusted time estimate for unit number 100?

There may be procedural differences in the manner that different firms collect and report data.

Which of the following is a reason that there are disparities between a firm's learning curve rate and that of its industry

4 repetitions of the job

With a 70 percent unit improvement factor learning curve and an initial time of 100 minutes to do a job, at what number of repetitions does the job take less than 50 minutes?

$58,600

You are a consultant called in to estimate the costs after the employees learn how to do a job more efficiently by repetition. Your client can produce a product the first time at a cost of $2,500. If their 65 percent Learning Curve allows them to reduce their costs on each product, what is the total cost of producing 400 units of the new product?

705.25 minutes

You have determined that a 60 percent learning curve is appropriate for a task. If your initial timing of person performing that task was 35 minutes and if you need the task performed 1,000 times, how many minutes of work will be required?

70 percent

You have just timed a person doing a hair cut for the first time. It took 50 minutes. What unit improvement factor learning curve would you use if the person took 35 minutes on the second hair cut?

75 percent

You have just timed a person doing a job a four times. The first time it took the person 120 minutes, the second time it took 90 minutes, the third time it took 76.1 minutes, and the fourth time it took 67.5 minutes. Which learning curve unit improvement factor should you use?
