One factor in determining how many cycles to time in a time study is the degree of variation that is present in the observed times.

Self-directed teams help other work groups make changes to their processes.

The owner of Kat Motel wants to develop a time standard for the task of cleaning a cat cage. In a preliminary study, she observed one of her workers perform this task six times, with the following results: How many observations should be made if she wants to be 95.44 percent confident that the maximum error in the observed time is 2 seconds? Assume that the standard deviation of the task time is 6 seconds.

Which of the following most closely describes job enlargement?

Predetermined time standards use historical data from a company's own files.

Which of the following is not an advantage of work sampling compared to stopwatch time study?

The owner of Kat Motel wants to develop a time standard for the task of cleaning a cat cage. In a preliminary study, she observed one of her workers perform this task six times, with the following results: What is the normal time for this task if the employee worked at a 50 percent faster pace than average?

Job design relates to people, therefore technology has little impact.

The methods analysis chart that describes the overall sequence of operations, transportation, storage, delays, and inspection is a:

In work sampling, how will increasing the permissible maximum error affect sample size?

The learning curve is a basic tool for mass production-type activities because it can deal with large volumes of output.

A methods and measurements analyst for Timepiece, Inc., needs to develop a time standard for the task of attaching a watch to a wristband. In a preliminary study, he observed one of his workers perform this task five times, with the following results: What is the standard time for this task if the employee worked at a 20 percent faster pace than average, and an allowance of 20 percent of the workday is used?

The standard time for a job can be obtained by multiplying the normal time by an appropriate allowance factor.

Ergonomics is the use of computers and robots in the workplace.

A job is expected to have a 70 percent learning curve. The first unit has been completed in 20 hours. Accordingly, the second unit can be expected to take approximately how many hours?

The quickest, most effective way to improve an employee's job satisfaction is to increase his or her compensation.

Methods analysis is particularly valuable when it is used on jobs that: (I) are high in labor content.(II) are done frequently.(III) involve a high degree of automation and mechanization.(IV) are unsafe, tiring, unpleasant, and/or noisy.

Job enrichment involves giving workers a greater share of the total task, which is why they feel enriched.
