Exam 10: Human Resources, Job Design, and Work Measurement

A time-study procedure involves timing a sample of worker's performance and using it to set a standard.

The accuracy of a labor standard is to be within 5%, and the confidence level is 95%. The standard deviation of the sample is 2 and the mean is 8. What sample size should be used?

__________ means a job that is not only reasonably safe and for which the pay is equitable, but which also achieves an appropriate level of both physical and psychological requirements.

An advantage of predetermined time standards is that the standard can be set before a task is actually performed.

When a worker obtains clear and timely information about his/her performance, his/her job is characterized by

Normal time equals the average observed time multiplied by the allowance factor. False

__________ refers to a work schedule that deviates from the normal or standard five 8-hour days.

__________ showed that there is a dynamic social system in the workplace.

If a manager conducting a time study needed an accuracy of ± 0.1 minutes, rather than ± 0.2 minutes, the adequate sample size would have to be twice as large.

A task involves positioning two metal parts with a rubber gasket sandwiched between them, inserting two bolts into predrilled holes, threading a nut onto each bolt, and tightening each bolt with a pneumatic wrench. In a preliminary study, the manager observed one of his workers perform this task five times. The observations were made in an air-conditioned, well-lighted training facility, at ground level, with all tools and equipment clean and readily available. a. What is the average observed time for this task? b. What is the normal time for this task if the employee worked at a 10% slower pace than is typical for adequately trained workers? c. What is standard time for this task if allowances are 8% constant and 6% variable?

Most pit crew members have background experience in what area?

Ethical work environment decisions by managers may be guided by

Which of the following terms implies an increase in responsibility and control in the vertical direction?

Standard time may be less than average observed time.

Profit-sharing is a motivation and incentive system where executives receive stock options.

Two uses of labor standards are to determine the labor content of items produced and to determine staffing needs.

What impact did the Hawthorne studies have on human resource strategy?

Kanbans and andons are both elements of the visual workplace, because they are visual signals that replace printouts and paperwork.

__________ allowances are those that include the distance from employees to restrooms, water fountains, and other facilities.

Labor planning determines employment stability.
