Question 1

A 90% learning curve implies that each time the production volume is doubled,the direct time per unit is reduced to 90% of its previous value.

Accepted Answer

The statement accurately describes the concept of a 90% learning curve.

Question 2

The fundamental premise underlying learning curve analysis is that:
A)tasks can be easily learned in organizations.
B)organizations and people become better at their tasks as the tasks are repeated.
C)learning takes place when people in organizations change.
D)total labor costs decrease as the number of production units increases.
E)doubling output cuts labor requirements per unit in half.

Accepted Answer

Learning curve analysis is based on the principle that as people and organizations repeat a task, they become more efficient and proficient in completing the task. This leads to a decrease in the time and cost required to complete the task, as well as an increase in productivity. The learning curve analysis shows the relationship between the number of units produced and the time or cost required to produce those units, and the curve demonstrates that as production increases, the time or cost per unit decreases.

Question 3

The earliest application of learning curves appears in the work of architect Frank Lloyd Wright.

Accepted Answer

The earliest application of learning curves was actually during World War II by the U.S. Air Force in order to improve production efficiency in the manufacturing of airplanes. Frank Lloyd Wright did not use or apply learning curves in his work.

Question 4

Experience curves are the opposite of learning curves-as one rises,the other falls.

Accepted Answer

Experience curves and learning curves both describe how costs decrease as experience and production increase, but they are not opposites. Both suggest that as more units are produced, the cost per unit decreases due to increased efficiency and learning.

Question 5

If the learning curve for a process is 100 percent,then each unit in a series of units will have the same labor requirements.

Accepted Answer

A 100 percent learning curve implies that each unit produced takes the same amount of time and effort as the previous one, indicating no improvement or reduction in labor requirements over time.

Question 6

An 80% learning curve means that with each unit increase in production,labor requirements fall by 20%.

Accepted Answer

The answer of An 80% learning curve means that with...

Question 7

The fact that human activities typically improve when they are done on a repetitive basis is described by a:
A)normal distribution curve.
B)binomial distribution curve.
C)learning curve.
D)Poisson distribution curve.
E)repetition curve.

Accepted Answer

The learning curve describes the phenomenon where human activities tend to improve with practice or repetition. This concept is important in fields such as manufacturing and project management, where improvements in efficiency and quality can be achieved through experience and repetition. Normal distribution, binomial distribution, and Poisson distribution curves are not relevant to the concept of the learning curve. "Repetition curve" is not a term used in statistics or scientific literature.

Question 8

A learning curve:
A)plots man-hours per dollar versus time.
B)is mathematically described by a parabola.
C)should be plotted on polar coordinate graph paper.
D)is based on the premise that organizations learn from experience.
E)follows a normal distribution.

Accepted Answer

The learning curve is based on the premise that organizations learn from experience. The other options are incorrect as the learning curve plots cumulative average time per unit versus cumulative number of units produced and does not follow a parabolic or normal distribution. It is also not plotted on polar coordinate graph paper.

Question 9

Learning curves (or experience curves)were first applied to industry by ________ who was studying ________.
A)Frank Lloyd Wright; architecture
B)Frank Gilbreth; worker efficiency
C)T.P.Wright; air frame manufacture
D)Lilian Gilbreth; factory efficiency
E)Frederick W.Taylor; scientific management

Accepted Answer

The learning curve concept was initially developed and applied by T.P. Wright in the late 1930s, while studying the manufacturing processes of airframes.

Question 10

If the first unit in a series of units takes 200 days to complete,and the learning curve is 80%,then the second unit will take 160 days.

Accepted Answer

The learning curve of 80% means that as the production of units double, the time to produce each subsequent unit decreases by 20%. Therefore, the second unit would take 80% of the time it took to produce the first unit:

160 = 200 * 0.8

So, the statement is true.

Question 11

Learning curves can only be applied to labor.

Accepted Answer

Learning curves can be applied to various resources, including labor, machines, and materials.

Question 12

Which of the following best conveys the essence of learning curves?
A)As the number of repetitions increases,time per unit increases.
B)As the number of repetitions decreases,time per unit increases.
C)As the number of repetitions increases,time per unit decreases.
D)As the number of repetitions increases,time per unit remains constant.
E)As the number of repetitions increases,time per unit doubles.

Accepted Answer

Learning curves depict the relationship between experience (number of repetitions) and time per unit of output. As experience increases (more repetitions), time per unit of output decreases, which means productivity increases. Therefore, the best choice is C.

Question 13

Experience curves may be valid for industrial applications,but have no role in services such as health care procedures.

Accepted Answer

While experience curves may be more commonly associated with industrial settings, they can still apply to services such as health care procedures. Experience curves track the improvement in efficiency and reduction in costs over time as individuals or organizations gain more experience with a task or process. This can apply to any field where repetitive tasks or processes are performed, including health care procedures.

Question 14

The learning curve rate is:
A)the percentage of time it will take to make each unit when the production rate doubles.
B)the log-log of the annual rate change divided by the average unit cost.
C)always based on constant value dollars.
D)only considered valid after one year of data is accumulated.
E)equal to at least 75%.

Accepted Answer

The learning curve rate refers to the rate at which the time to produce each additional unit decreases as the total number of units produced doubles. It is a reflection of increased efficiency and productivity over time as experience is gained.

Question 15

A 100% learning curve implies that:
A)learning is taking place for all products and workers.
B)learning is taking place at the best possible level.
C)a 100% reduction in the direct labor time takes place each time the production is doubled.
D)no learning is taking place.
E)None of the above is true.

Accepted Answer

The answer of A 100% learning curve implies that:
A)learning is...

Question 16

Which of the following statements is most appropriate with respect to a 70% learning curve?
A)There will be a 70% decrease in direct labor per unit each time the production volume doubles.
B)Each successive unit of production will take 70% of the direct labor of the previous unit.
C)There will be a 30% decrease in direct labor per unit each time production volume doubles.
D)Thirty percent of the production will be defective until full learning takes place.
E)None of the above is true.

Accepted Answer

The answer of Which of the following statements is most...

Question 17

Which one of the following statements about learning curves is TRUE?
A)A learning curve assumes that the direct labor requirements per unit will DECREASE at an INCREASING rate as cumulative production increases.
B)A larger learning curve rate implies faster (greater)learning.
C)A learning curve graph usually follows a negative exponential curve.
D)Learning curves can be used only for individuals,not for the whole organization.
E)The formula describing the learning curve principle of doubling is computed differently when computing unit cost as opposed to unit time.

Accepted Answer

A learning curve graph usually follows a negative exponential curve. The curve shows the decrease in the time required to produce a unit as more units are produced. The rate of improvement slows down over time as the process reaches its optimal level. The formula used to compute the learning curve is based on a power law relationship between unit cost and cumulative production. The rate at which learning occurs is expressed by the learning curve rate, which reflects the percentage reduction in direct labor time for each doubling of output. However, choice A is incorrect because the learning curve assumes that the direct labor requirements per unit will DECREASE, but not necessarily at an increasing rate. Choice B is incorrect because a larger learning curve rate implies slower (lesser) learning. Choice D is incorrect because learning curves can be used for both individuals and organizations. Choice E is incorrect because the formula for the learning curve principle of doubling is the same for both unit cost and unit time.

Question 18

Learning curves are based on the premise that people and organizations become better at their tasks as the tasks are repeated.

Accepted Answer

Learning curves show that as individuals or organizations repeat a task, they become more proficient at it and thus increase their efficiency and productivity.
