Exam 7: Work Design and Measurement

Methods analysis is more likely to lead to a relatively easy and successful implementation of an improved method if workers have been consulted throughout the process than if the analyst assumed sole responsibility for the development of the improved method.

The manager of Lawn and Garden Services would like to estimate the proportion of her employees' time spent performing various gardening and lawn care activities. She has made 400 random observations of a typical worker, with the following results: What is the most likely true proportion of time spent mowing?

Motivation influences quality and productivity, but not the work environment.

In calculating standard times, allowance percentages normally would consider all of the following except:

Which of the following is not characteristic of time-based compensation plans?

A worker-machine chart can help identify nonproductive parts of a process.

Negotiated purchasing results in lower unit costs for smaller quantities.

A manager wants to analyze the learning curve associated with producing one of his company's products. Accordingly, he has gathered the following data: Approximately how long will it take to produce the fifth through tenth units?

For an 80 percent learning curve, if the first unit requires 10 hours, the second unit will require 8 hours and the third 6.4 hours.

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: How many observations should be made if he wants to be 95.44 percent confident that the maximum error in the observed time is 1 second? Assume that the standard deviation of the task time is 5 seconds.

A job has an 80 percent learning curve. If the first unit took 40 hours to complete, the fourth unit should take roughly how many hours?

Learning curves are mostly relevant for complex, new activities that have not been done often.

One therblig is the equivalent of 1 hour of sustained work by one average person.

To which worker would learning curves be most applicable?

A behavioral approach to job design that increases responsibility for planning and coordinating tasks is job:

The symbols for operation, storage, transportation, inspection, and delay would usually be found on which type of chart?

To which of the following challenges are learning curves important considerations?

The methods analysis chart that describes the portions of a work cycle during which an operator and equipment are busy or idle is a:

Which of the following can affect the ways in which learning curves may be applied?

Determining the number of cycles to observe is an element of:
