The 50^th repetition of a job is timed at 100 minutes.If the learning curve for this job is 90 percent, what is the estimated time for the 100^th repetition of this job?

An assumption of learning curve theory is which of the following?

Describe an example of industrial learning where learning curve analysis might be useful.

You are a consultant called in to estimate the costs after the employees learn how to do a job more efficiently by repetition of new product.You find a company can produce a product the first time at a cost of $5,000.If their 90 percent learning curve allows them to reduce their costs on each unit, what is the total cost of producing 100 units of the new product?

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

The unit improvement factor for a 60 percent learning curve at 25 units is 0.0933.The first and second timings of a person doing a job are 5 minutes and 3 minutes, respectively.The learning-adjusted time estimate for the unit number 25 is 0.0933 minute.

Why are learning curves useful in business?

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?

What are some of the factors that stimulate learning?

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

A company can produce a small lot of products the first time at a cost of $10,000.If their 75 percent learning curve allows them to reduce their costs on each lot, what is the total cost of producing 10 lots?

You time someone completing a single task the first time at 120 minutes, and the second time they do the task it takes 108 minutes.You should use a 90 percent learning curve to estimate the length of time this worker will take to complete this task in the future.

You are a consultant specializing in estimating 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?

The unit improvement factor is not as useful as arithmetic tabulation of learning curve statistics in adjusting time estimates for learning.

You time someone completing a single task the first time at 100 minutes, and the second time they do the task it takes 90 minutes.You should use a 90 percent learning curve to estimate the length of time this worker will take to complete this task in the future.

A company can produce a product the first time at a cost of $2,500.If its 85 percent learning curve allows the company to reduce its costs on each product, what is the total cost of producing 400 units of the new product? _________________

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 very first 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?

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