Exam 11: Human Resources, job Design, and Work Measurement

Personal and fatigue allowances can include amounts for the effects of lighting,heat and humidity,and noise.

How many observations would be necessary for a time studies analyst to be 99% confident that the average time is within ± .1 minutes of the true value,if the average time is 10.5 minutes and the standard deviation is 3 minutes?

Labor standards were pioneered by Frank and Lillian Gilbreth and:

Job rotation is a version of job enlargement.

Which of the following is a visual signal at a machine that notifies support personnel about the machine's status?

An operation in a television factory has an average observed time of 6 minutes.The performance rating of the worker timed was estimated at 90%.Practice in this department is to provide 8% for allowances. a.Find the normal time for the operation. b.Compute the standard time for the operation. c.Recompute the standard time if an additional fatigue allowance of 8% is factored in.

The average observed time for a given job is 10 minutes.The performance rating is 80%,and allowances are set by contract at 10%.What is the standard time?

The allowances that convert normal time to standard time have three components: personal time allowances,delay allowances,and fatigue allowances.

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. 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)work environment,and that the proper allowance was not 14% but 20%,what is the revised standard time?

Often called human factors,the study of work is known as ________.

Identify the five steps of the work-sampling procedure.

________ systems provide some portion of any profit for distribution to employees.

A bank manager wants to determine the percent of time the bank's tellers are working and idle.He decides to use work sampling,and his initial estimate is that the tellers are idle 20% of the time.Approximately how many observations should be taken to be 95% confident that the results will not be more than 5% away from the true result?

An operations chart,or right-hand/left-hand chart,points out wasted motion and idle time.

One use of labor standards is to determine what constitutes a fair day's work.

The physical environment in which employees work may affect the quality of work life,but it does not affect their performance and safety.

What is methods analysis?

What is mutual trust? What is its link to a firm's human resource strategy?

What are the advantages and the disadvantages of the employment-stability policy of "hold employment constant?"

The two extremes of employment stability policy are "follow demand exactly" and "keep demand constant."
