Which of the following is a true statement about learning curves? [multiple answers may apply]a. if a worker following a 60% learning curve required 18.32 seconds to complete the 10th unit, that worker should require approximately 10.99 seconds to complete the 40th unit. b. a main source of organizational learning stems from individual learning. c. if a worker following a 95% learning curve required 84.33 seconds to complete the 10th unit, that worker should require approximately 76.11 seconds to complete the 40th unit. d. learning curves may also play a synergistic role with economies of scale in reducing costs and improving efficiency. e. as discussed in class, allowing workers to redesign their tasks and suggest process improvements can be beneficial for both individual learning and organizational improvement. f. from our notes, a major managerial consideration is that we should work harder, not smarter. g. a worker operating on a 90% learning curve will be slower than a worker operating on an 80% learning curve. h. the point at which the economy of scale curve and the learning curve intersect is called the capacitated optimum. i. an assumption of learning curves is that the time required to complete a unit will decrease at a increasing rate as the cumulative number of units completed increases.
