Deck 12: Supplement Operational Decision-Making Tools: Work Measurement

Question 1

In a time study the standard time is computed by

B)dividing the average elemental time by the rating factor
C)multiplying the normal cycle time by the rating factor
D)multiplying the normal cycle time by one plus the allowance factor

Answer 1

D

Question 2

In work measurement,a performance rating factor

A)allows the transferability of a standard to other workers
B)does not require that the analyst be specially trained
C)is the same regardless of the effort and skill of the operator observed
D)converts the time of the operator observed to the expected performance of the best worker

Answer 2

A

Question 3

A retail catalog company wants to perform a work sampling study of its call center,and if the company estimates its operators are busy answering calls 80% of the time,and it wants the study to be accurate with + or - 4% with a 95% degree of accuracy,the number of sample observations the study should include is approximately

A)8
B)49
C)384
D)2,401

Answer 3

C

Question 4

In a work sampling study the percentage of time a worker is idle is called the

A)normal time proportion
B)sampling error
C)sampling period
D)ratio delay

Question 5

A primary use of work sampling is to analyze jobs that have

A)very short,clearly defined tasks
B)highly repetitive tasks
C)non-repetitive tasks
D)a large number of tasks

Question 6

A company conducted a single sample of a time study for 10 cycles of a job and if the average cycle time was 0.60 minutes,and the standard deviation of the sample was 0.075 minutes,for the company to be 95% confident that the average time computed for the time study is within 5% of the true average cycle time,the time study would need to encompass

A)16 cycles
B)20 cycles
C)24 cycles
D)32 cycles

B)predetermined motion times
C)time measurement units
D)normal cycle times
