Exam 15: Work Measurement

When using a time-study approach,the standard time is

Which of the following is not an advantage of the predetermined-data approach to work measurement?

A work standard is the time required for a trained worker to perform a task following a prescribed method with normal effort and skill.

The methods time measurement system is a predetermined data system.

A worker was observed for four cycles in a repetitive task that contains four distinct elements. The observer recorded the following items in seconds, using the continuous method. Element Cycle 1 Cycle 2 Cycle3 Cycle4 12 66 111 168 21 75 122 185 37 86 133 200 53 89 146 209 -Use the information in Table H.1.Assume that work element 1 receives a performance rating factor of 1.2 and all other elements receive a rating of 1.1.If work element 2 is performed every other cycle but every other element is performed every cycle,and the company has an allowance time of 0.10,what is the standard time for the complete cycle?

Work measurement is the process of creating labor standards based on the judgment of skilled observers.

Traditional work measurement techniques often are viewed as repressive.

A time-study analyst has found the select time for a work element to be 14.0 minutes,with a sample standard deviation of 3.2 minutes.What is the minimum sample size needed if the estimate is to be within 4 percent of the average 95 percent of the time?

Which one of the following statements about the time-study method is TRUE?

The key to creating a work standard is defining ________.

Are time standards more useful for manufacturing or service processes? Why?

Elemental standard time data can help managers develop time standards for new work before production begins.

The most commonly used method for setting a time standard is called a(n)________.

The snap-back method of time study resets the stopwatch to zero on the completion of each work element.

An industrial engineer is conducting a time study for a work element.The select time is 7.5 minutes,and the sample standard deviation of the observed time is one minute.What is the appropriate sample size if the estimate is to be 3 percent of the true average time 95 percent of the time?

An analyst using a time-study approach

A worker was observed for four cycles in a repetitive task. The observer recorded the following times, in seconds, using the continuous method. The ratings for each element and frequency it is performed are also indicated in the table. The allowance fraction is 20 percent. Element Cycle 1 Cycle 2 Cycle 3 Cycle 4 Rating Frequency 15 106 208 309 1.10 1.0 37 131 234 334 1.05 0.5 47 143 245 348 1.20 0.5 90 190 293 392 1.15 1.0 -Use the information in Table H.3.What is the select time for work element 2?

Which of the following is TRUE regarding the MTM approach?

During a time study,the following times were observed for a particular job using the continuous (non-snapback)method: 22,51,72,98,128,and 150 seconds.There is only one element per cycle.The sample standard deviation of the observed times has already been computed as 3.9 seconds.If an estimate for the average time that is within 4 percent of the true long-range average 95 percent of the time is desired,how many additional observations are needed?

The performance-rating factor in a time study is a totally objective measure.
