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.
Estimate the number of repetitions each of the workers listed in the following table will require to achieve a standard time of 25 minutes per repetition. Time is in minutes.

- Leading refers to guiding the efforts of human resources to ensure high levels of task accomplishment. True Falsearrow_forwardThe time study of a work operation at a restaurant yielded an observed time of 4 minutes. The analysis rated the observed worker at 85%. This means the worker performed at 85% of normal when the study was made. The firm uses a 13% allowance factor. The restaurant wants to compute the normal time and the standard time for this operation;arrow_forwardYou want to know the standard time of a welding process. The analyst has obtained the followingi information: average timed time - 1.30 minutes rhythm assessment - 110 fixed supplements - 5% variable supplements - 2% Determine the standard time, in minutes, of the welding process: a) 143 min b) 145 min c) 150 min d) 153 minarrow_forward
- 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_forwardCan be done by hand.

- The “worker” in this scenario had to perform a candy-sorting task and the rest of the class had to record the observed times (OT) for the task. 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.

The worker’s time averaged 1.9 minutes per cycle, and the worker was given a rating of 120 percent (machine rating is 100 percent). Midway through the study, the worker took a 10-minute rest break. Assuming an allowance factor of 12 percent of work time, determine the standard time for this job.arrow_forward8. A furniture company just completed a work analysis on the total completion time for dying process of handmade dining tables. They have concluded that on average the process takes 27 minutes. However they want to incorporate the performance of the workers and allowance time on this observed value. They think the people they observed was somehow slow, hence they want to use a performance rate of 0.93 and they also want to allow 10% (allow=0.1) of job time. Based on these parameters please calculate the normal and standard time estimates for this process.arrow_forward
- A recently negotiated union contract allows workers in a shipping department 24 minutes for rest, 10 minutes for personal time, and 14 minutes for delays for each four hours worked. A time study analyst observed a job that is performed continuously and found an average time of 6.0 minutes percycle for a worker she rated at 95 percent. What standard time is applicable for that operation?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_forwardI Love Lucy: A Colorized Celebration - "Job Switching" clip https://youtu.be/K3axU2b0dDk Watch this short "I Love Lucy" clip. In it, you will see Lucy and her friend Ethel wrapping candies on an automatic assembly line. Their job is to make sure that each candy is wrapped. You will laugh when you see what happens as the speed increases on the line. Think about this clip from the point of view of operations management. This clip is much more than poor management techniques. So - what went wrong? What would you do to improve the process? Answer these questions with concepts from this week's readings.arrow_forward
