Exam 23: Measuring Output Rates

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 normal time for work element 2?

Which one of the following statements about work measurement is TRUE?

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

An undergraduate business student studies diligently in the library during dead week in anticipation of an outstanding performance on her final exams.She asks a friend to spy on her at random intervals to determine what percentage of time she is actually studying.Over the course of three days,her friend records the following observations: If the student wants a 95 percent confidence level (z = 1.96)and a degree of precision of + 0.08,how many more observations are needed?

An analyst divides each work element into a series of micro-motions common to a variety of tasks when using the ________.

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?

The more frequently the activity occurs,the longer the time period should be when conducting a work sampling study.

A time study analyst is attempting to determine the standard time for a work element.She or he observes a worker performing the work element at a lower-than-average pace.How will this fact be reflected in the time standard that is eventually created?

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

Table H.2 -Use the information in Table H.2.If the allowance for this task is 20 percent,what is the standard time for the entire task?

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

A pilot work study has been conducted on a new operation with four work elements.The following times,in seconds,were obtained using the continuous method. a.What is the normal time for this operation? b.If an allowance of 20 percent is used,what is the standard time for this task? c.What sample size is appropriate for estimating the time for element 3 within + 3 percent of the true mean time with 95 percent confidence (z = 1.96)?

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

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

The standard time for a work element is found by multiplying the select time by a performance 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?

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

With the use of the methods time measurement approach:

An observer has recorded the following select ( )for a five-part task and has applied a rating factor (RF)to each.The times are in seconds.If there is a 15 percent allowance for "nonproductive" activities,compute the standard time for the total task. The standard time for the task is:
