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_forward

A particular job that has been under analysis aspart of a quality-improvement program was the subject of atime study. The time study encompassed 20 job cycles, and the results include the following cumulative times and per-formance rating factors for each element: a. Compute the standard time for this job using an al-lowance factor of 15%. b. Using a sample standard deviation of 0.51 minutes, de-termine the number of cycles for this time study such that the company would be 95% confident that the av-erage time from the time study is within 5% of the true average cycle time.arrow_forwardA 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% (machine rating is 100%). Midway through the study, the worker took a 10-minute rest break. Assuming an allowance factor of 12% of work time, determine the standard time for this job. Hints: you should consider both machine time and machine time together. Also, Allowance only applies to the man, not a machine.arrow_forward
