Summary Introduction
To determine: The person who is capable of reaching the 10th unit by 1 hour.
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.

Providence Assessment Center screens and trains employees for a computer assembly firm in Boston. 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

- local market research fim has just won a contract for several thousand small projects involving data gathering and statistical analysis. In the past, the firm has assigned each project to a single member of its highly trained professional staff. This person would both gather and analyze the data Using this approach, an experienced person can complete an average of 10 such projects in an eight-hour day. The firm's management is thinking of assigning two people to each project in order to allow them to specialize and become more efficient The process would require the data gatherer to fill out a matrix on the computer, check it and transmit it to the statistical analysis program for the analyst to complete. Data can be gathered on one project while the analysis is being completed on another, but the analysis must be complete before the statistical analysis program can accept the new data. After some practice, the new process can be completed with a standard time of 20 minutes…arrow_forwardene is working with the operations manager to determine what the standard labor cost is for a spice chest. He has watched the process from start to finish and taken detailed notes on what each employee does. The first employee selects and mills the wood, so it is smooth on all four sides. This takes the employee 1 hour(s) for each chest. The next employee takes the wood and cuts it to the proper size. This takes 43 minutes. The next employee assembles and sands the chest. Assembly takes 3 hour(s). The chest then goes to the finishing department. It takes 3 hour(s) to finish the chest. All employees are cross-trained so they are all paid the same amount per hour, $17.62. What is the standard cost per chest for labor? Round to the nearest penny, two decimal places.arrow_forwardA time study analyst timed an assembly operation for 30 cycles, and then computed the average time per cycle, which was 18.75 minutes. The analyst assigned a performance rating of .96, and decided that an appropriate allowance was 15 percent. Assume the allowance factor is based on the workday. Determine the following: the observed time (OT), the normal time (NT), and the standard time (ST).arrow_forward

Use the Work Measurement Excel template to determine the standard time for this operation.arrow_forwardRecently, the polish general corporation,well-known for manufacturing appliances and automobile parts, initiated a $13 billion project to produce automobiles. A great deal of learning on the part of management and employees was required. Even though pressure was mounting to get a new product in early 2012, the production manager of the newly formed automobile division insisted on almost a year of trial runs before sales started because workers have to their jobs 60 to 100 times before they can memorize the right sequence.
