A firm has a training program for a certain operation. The progress of trainees is carefully monitored. An established standard requires a trainee to be able to complete the sixth repetition of the operation in six hours or less. Those who are unable to do this are assigned to other jobs.Currently, three trainees have each completed two repetitions. Trainee A had times of 9 hours for the first and 8 hours for the second repetition; trainee B had times of 10 hours and 8 hours for the first and second repetitions; and trainee C had times of 12 hours and 9 hours.Which trainee(s) do you think will make the standard? Explain your reasoning.
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
Learning rate (%) – doubling concept
Time for the 1st unit
Time for the 10th unit
Estimate the number of repetitions that new service worker Irene will require to achieve “standard” if the standard is 18 minutes per repetition. She took 30 minutes to do the initial repetition and 25 minutes to do the next repetition.

- 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.

It was decided that the rating for the “worker” was 100%. Given the following table, find the standard time for each element. Write your answers in order from Element #1 --> Element #5. Answers must have one decimal place: e.g. 3.0 or 12.5. Round up if necessary. Assume a total allowance of 5%. In your equation you will use for ST, consider allowance to be 0.05.
