Concept explainers
a)
To determine: The time taken for completing the 1st unit.
Introduction:
Learning curve:
Learning curve is based on the premise that when a person is repeating a task or job again and again, the performance of the person on that job or task will improve. It will depict relationship between cost and output over a definitive period of time.
b)
To determine: The time taken for completing the 8th unit.
Introduction:
Learning curve:
Learning curve is based on the premise that when a person is repeating a task or job again and again, the performance of the person on that job or task will improve. It will depict relationship between cost and output over a definitive period of time.
c)
To determine: The time taken for completing all the 8 units.
Introduction:
Learning curve:
Learning curve is based on the premise that when a person is repeating a task or job again and again, the performance of the person on that job or task will improve. It will depict relationship between cost and output over a definitive period of time.

- K Girish Shambu and Delores Reisel are teammates at a discount store; their new job is assembling bicycles for customers. Assembly of a bike has a learning rate of 80%. They forgot to time their effort on the first bike, but st 5 hours on the second. They have 6 more bikes to do. Determine approximately how much time will be (was) required for: a) The 1st unit = 6.25 hours (round your response to two decimal places). b) The 8th unit = 3.20 hours (round your response to two decimal places). c) The total amount of hours to build the 8 units = hours (round your response to two decimal places).arrow_forward* Girish Shambu and Delores Reisel are teammates at a discount store, their new job is assembling bicycles for customers.

The progress of all trainees is tracked, and those not showing the proper progress are moved to less demanding programs. By the tenth repetition, trainees must be able to complete the assembly task in 1 hour or less. Susan has just spent 5 hours on the fourth unit and 4.5 hours completing her eighth unit, while another trainee, Julie took 4 hours on the third and 2.8 hours on the sixth unit. Should you encourage either or both of the trainees to continue? Why? Present calculation steps. [Hint: For each trainee, 1) Determine the learning rate (%) – use doubling concept. 2) Calculate time for the 1st unit (T1) – use table, 3) Calculate time for the 10th Unit (T10) –use table] Susan Julie Learning rate (%) – doubling concept Time for the 1st unit Time for the 10th unitarrow_forward
