Work measurement concentrates on how long the tasks take to accomplish.

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 normal time for this task if the employee worked at a 20 percent faster pace than average?

Predetermined time standards are usually based on observing one very efficient worker performing the task.

According to learning curve theory, for certain kinds of tasks the cost per unit decreases as the number of repetitions increases.

A technique for estimating the proportion of time a worker spends on various activities is:

If an 80 percent curve is appropriate for a task and the first unit takes 10 hours, the average time for the first 2 units would be 8 hours.

A manager wants to analyze the learning curve associated with producing one of his company's products. Accordingly, he has gathered the following data: How long did it take to produce the first unit?

The normal time in time study is obtained by multiplying the observed time by the performance rating.

An advantage of work sampling, compared to a stopwatch time study, is that observations are spread out over a period of time in work sampling.

Which of the following statements should not characterize an operations strategy toward the design of work systems?

A methods and measurement analyst wants to develop a time standard for a certain task. In a preliminary study, he observed one worker perform the task six times with an average observed time of 20 seconds and a standard deviation of 2 seconds. 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?

Which of the following is not an advantage of time-based pay systems?

If we have never made the first unit but only think we know how much the labor time will be, we cannot draw a learning curve.

A job will have a learning rate of 75 percent. If the third unit requires 10 hours, the twelth unit should require about this many hours:

The design of work systems typically involves: (I) work measurement.(II) job design.(III) compensation.(IV) the use of outside consultants.

A company is preparing a bid on a government contract for 40 units of a certain product. The operations manager estimates the assembly time required for the first two units to be 10.4 hours and 8.8 hours.Which unit, if any, will require approximately one-half the time of the first unit?

Time-based systems compensate employees according to the time they have worked and the amount of output they produce.

A company is preparing a bid on a government contract for 40 units of a certain product. The operations manager estimates the assembly time required for the first two units to be 10.4 hours and 8.8 hours.Approximately how long will it take to produce the 25th through thirtieth units?
