Exam 25: Supplement H Measuring Output Rates

A(n) ________ is the time required for a trained worker to perform a task following a prescribed method with normal effort and skill.

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 snap-back method: -The observer assigned a performance rating factor of 1.15 to the worker and the company employs an allowance factor of 20%. What is the select time for Element 2?

The ________ is a measurement found by multiplying the select time, the frequency of work, and the rating factor.

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 snap-back method: -The observer assigned a performance rating factor of 1.15 to the worker and the company employs an allowance factor of 20%. What is the normal time for Element 3?

Keith assembles peanut valves and the recorded data is displayed in the table. What is the select time for this job element?

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 snap-back method: -The observer assigned a performance rating factor of 1.05 to the worker and the company employs an allowance factor of 15%. What is the select time for Element 1?

The ________ of job element timing requires that the observer reset the stopwatch after each observation.

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

A time study analyst is determining the standard time for a work element. The select time is 6.0 minutes, and the standard deviation of the select time is 2.2 minutes, based on a pilot sample of 20 observations. What is the appropriate sample size if the estimate for the select time is to be within 10 percent of the True average time 95 percent of the time (z = 1.96)?

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 (z = 1.96) and a degree of precision of + 0.03, how many more observations are needed?

Fatigue, rest, or unavoidable delays are not factored into a work standard by the performance rating factor.

A larger sample size is required when the time estimate must be more certain.

The ________ is the average observed time based only on representative times.

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

Table H.2 -Use the information in Table H.2. Which work element will take the longest for an average worker to perform per cycle?

Time studies are appropriate for setting time standards for tasks that are different each time.

Name the four steps in a time study.

Traditional work measurement techniques are sometimes viewed as repressive and not conductive to good management-employee relations.

Keith assembles peanut valves and the recorded data is displayed in the table. During one of the cycles, he pauses to answer a phone call from his friend who suggests that he seek employment elsewhere. Keith fields calls with some regularity, but that's not considered part of his routine job responsibilities. What is the select time for this job element?

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 select time for work element 4?
