A sewing operator at the Gameday Sportswear Company assembles baseball-style caps with a team logo from precut wedges of material that form the crown, a precut bill, and additional precut pieces of material for the headband and reinforcing. The job encompasses seven basic elements. A time technician for the company has conducted a time study of the job for 20 cycles and accumulated for the following elemental times and assigned performance ratings:

- A worker-machine operation was found to involve 3.3 minutes of machine time per cycle in the course of 40 cycles of stopwatch study. 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_forwardTOYS AND JOB DESIGN AT THE HOVEY AND BEARD COMPANY The following is a situation that occurred in the Hovey and Beard Company, as reported by J. V. Clark. This company manufactured a line of wooden toys. One part of the process involved spray painting partially assembled toys, after which the toys were hung on moving hooks that carried them through a drying oven. The operation, staffed entirely by women, was plagued with absenteeism, high turnover, and low morale. Each woman at her paint booth would take a toy from the tray beside her, position it in a fixture, and spray on the color according to the required pattern. She then would release the toy and hang it on the conveyor hook. The rate at which the hooks moved had been calculated so that each woman, once fully trained, would be able to hang a painted toy on each hook before it passed beyond her reach. The women who worked in the paint room were on a group incentive plan that tied their earnings to the…arrow_forwardWhat are the trade offs in choosing between time study and work sampling for work measurement.arrow_forward
- The first day of basic training at the Air Force Academy is quite a sight, with 1500 cadets being processed in. This involves getting haircuts, uniforms, room assignments, and a mountain of paperwork. At the Uniform Fitting station, the worker takes the measurements on the cadet (which takes about 2 minutes), then retrieves shirts, pants and hats in his/her size (which takes about 2 minutes), waits for the cadet to try on the pants (which takes about 1 minute) and then marks the pants for hemming (which takes about 1 minute). The in-processing takes place from 8 AM to 5 PM with an hour off for lunch (8 hours). __________2a. How many cadets can a single worker fit for uniforms on that hectic day? __________2b. How many workers would be needed to fit 1601 cadets in one day, if everyone works at full capacity?arrow_forwardA 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_forwardFor a time study of a health insurance claims-adjusting process, the analyst uses the continuous method of recording times. The job is divided into four work elements. Shown in Figure are the performance rating factors, RF, and the continuous method recorded times, r, for each work element.a. Calculate the normal time for this job. b. Calculate the standard time for this job, assuming that the allowance is 20 percent of the normal time. c. What is the appropriate sample size for estimating the time for element 2 within {10 percent of the true mean with 95 percent confidence?arrow_forward
- Create a swim-lane process map for placing and receiving an order at a fast food restaurant. Please choose a restaurant where you can see the food being prepared (e.g Panera Bread, McDonalds, Arbys, Subway, Taco Bell, etc.). > Your process map will have three swim-lanes: you, cashier (taking your order), and cook (preparing food). You do not need to include any metrics (times, distances, etc.).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_forwardNonearrow_forward
- 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 unitarrow_forwardDescribe the idea behind the term "procedure." What makes a process different from a planned activity?arrow_forwardData Products, Inc., packages and distributes a variety ofpersonal computer-related products. A time study hasbeen conducted for a job packaging 3.5-inch personalcomputer diskettes for shipment to customers. The jobrequires a packager to place 20 diskettes in a rectangularplastic bag, close the bag with a twist tie, and place thefilled bag into a bin, which is replaced by another workerwhen it is filled. The job can be broken into four basic elements. The elemental times (in minutes) were ob-tained from the time study for 10 job cycles shown in the following table. a. Using an allowance factor of 16%, determine the stan-dard time for this job. b. Determine the number of cycles for this time studysuch that the company would be 95% confident that theaverage time from the time study is within 4% of thetrue average cycle time.arrow_forward
