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. 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. 13) 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 14) A job with a 90% learning curve required 20 hours for the initial unit. The fourth unit should require approximately how many hours? A) 16.0 B) 16.2 C) 18.0 D) 20.0 E) 54.2 15) 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. 16) 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. 17) 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. 18) 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%. 19) 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. 20) The earliest industrial application of learning curves came from a report by ________. 21) ________ are based on the premise that people and organizations get better at their tasks as the tasks are repeated.
