In a time study, if the analyst determines that a worker under observation is working at a faster than normal pace, the analyst will use a performance rating (rating factor) that is
| A. | a negative number. | |
| B. | between zero and 1.00 (100%). | |
| C. | equal to 1.0 (100%). | |
| D. | greater than 1.0 (100%). |
Expert Answer
Performance seldom conforms to normal standard because of various factors. Thus while a task may have a Normal time for completion, it becomes essential to add some adjustment factor to the Observed time to arrive at Normal time of the operation for the said task. This adjustment is called Performance Rating.
The concept o Rating Factor is thus introduced to compare Observed time vs Normal time for an operation and Rating Factor is thus defined as :
Rating Factor = Observed time / Normal time
In the given problem, the observed time is faster than Normal time , i.e. Observed Time < Normal Time.
Thus Rating Factor which is “Observed time / Normal time “ < 1 and will be fraction between 0 and 1
Therefore correct answer will be “B. between zero and 1 ( 100%)”
| ANSWER : b) BETWEEN ZERO AND 1 ( 100%) |
