Exam 16: Work Measurement

A worker was observed for four cycles of a repetitive task.The observer used the continuous method for recording the times.The continuous times (in seconds)for each element are: Which one of the following are the "select times" ( )for each element? The first number is the select time for the first element,the second number is the select time for the second element,and so on.

Table H.1 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. -Use the information in Table H.1.Work element 1 receives a performance-rating factor of 1.4 and is performed every other cycle.If the company uses an allowance time of 15 percent,what is the standard time for this work element?

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?

Which work-measurement technique breaks down tasks into a series of generic micro-motions?

The predetermined data approach eliminates the need for time studies.

A worker was observed for four cycles of a repetitive operation.The observed times for work elements are 11,10,8,and 11 seconds,respectively.What sample size is appropriate for estimating the time for this work element within + 3 percent of the true mean time with 95 percent confidence?

When using a work-sampling study,

With a time-study approach,the

When using work sampling,the times of day when the analyst collects the sample data should be selected at random over the length of the study.

Table H.3 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. -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?

A manager wants to determine the proportion of time a cashier is idle.A work-sampling method was used,and the idle time was found to be 20 percent based on 100 observations.If the manager wants a + 0.05 with a 95 percent confidence level,how many MORE observations are needed?

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

A time study is the method most often used for setting time standards for a job.

With the use of the methods time measurement approach,

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

Table H.3 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. -Use the information in Table H.3.What is the normal time for work element 2?

A work-sampling method is used to determine the proportion of the time a worker is idle.The following information was gathered on a random basis. If the manager wants a 95 percent confidence level and a degree of precision of ± 0.03,how many MORE observations are needed?

Table H.3 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. -Use the information in Table H.3.What is the standard time for work element 1?

Traditional work measurement techniques often are viewed as repressive.
