Exam 22: Learning Curves

With an 80 percent unit improvement factor learning curve and an initial time of 100 minutes to do a job,at what number of repetitions will the job take less than 50 minutes?

Learning curves have a wide range of business applications.

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.

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?

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?

The unit improvement factor for a 60% 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.Which of the below is the learning-adjusted time estimate for unit number 25?

What is a learning curve?

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

The unit improvement factor for a 60% learning curve at 25 units is 0.0933.The first and second timings of a person doing a job are 10 minutes and 6 minutes respectively.The learning-adjusted time estimate for the unit number 25 is 0.9330 minutes.

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

You have determined that a 75 percent learning curve is appropriate for a task.If the initial timing of the person performing that job was 50 minutes and if you need the job performed 500 times,how many minutes of work will be required?

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

The unit improvement factor for a 60% 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 minutes.

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?

A company's production process has an 80 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?

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?

What are some of the possible factors that stimulate learning?

Why are learning curves useful in business?

You time someone completing a single task the first time at 100 minutes and the fourth time they do the task it takes 81 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.

The unit improvement factor for an 80% 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?
