Compare stopwatch time study and work sampling.
Describe the steps involved in conducting a work sampling study.
A Methods and Measurements Analyst needs to develop a time standard for a certain task. The task involves use of a ruler, square, and portable electric saw to mark and cut the "notch" in a rafter (a standard carpentry task of home construction). In a preliminary study, he observed one of his workers performing this task five times. The observations were made in an air-conditioned, well-lit training facility, at ground level, with all tools and equipment clean and readily available.
Observation:

a. What is the actual average time for this task?
b. What is the normal time for this task if the employee worked at a 20% faster pace than is typical for adequately trained workers?
c. What is standard time for this task if allowances sum to 14%?
d. If the analyst then thought more carefully about his experiment and decided that the allowances needed to be increased to match the real (outside, not air-conditioned)…

- TOYS 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 situations call for the use of work sampling instead of time study?arrow_forwardIf an average worker could be identified, what advantage would there be in using that person for a time studyarrow_forward
