TOPIC: ARGUMENT186 - The following is a recommendation from the director of personnel to the president of Professional Printing Company.
"In a recent telephone survey of automobile factory workers, older employees were less likely to report that having a supervisor present increases their productivity. Among workers aged 18 to 29, 27 percent said that they are more productive in the presence of their immediate supervisor, compared to 12 percent for those aged 30 or over, and only 8 percent for those aged 50 or over. Clearly, if our printing company hires mainly older employees, we will increase productivity and save money because of the reduced need for supervisors."
Basing on a recent telephone survey, supposing that older workers of automobile factory do not to need supervisor present for increasing productivity, the author assert that in order to increase productivity and save money by reducing supervisors, the printing company should employee mainly older workers. It seems to be a reasonable deduction, while a close examination would reveal how groundless it is.
To begin with, the author has analyzed the data of survey with several critical flaws. He or she fails to provide any information concerning all the details that may lead to a unreasonable conclusion. The threshold problem is that how much specific amount of investigated subjects in different age groups in the survey has not been presented in the argument. It is possible that the amount of subjects investigated in different groups are not equal: the most amount of workers in the telephone survey is 18 to 29 years old, workers aged 30 or over are fewer and those aged 50 or over are the least. Secondly, assuming the survey did not search all the workers in the automobile factory, the representative role of the subject’s response in the total is worth considering, because the author lends no information about the proportion of subjects among all workers. Thus, to improve more efficiency, the author must present more information about something above, or it would cause a suspicion to the credible of the survey.
What further weakens the conclusion is the fact that the concrete circumstance in the printing company might be distinctive comparing to the automobile factory's. That is to say, the plan the author made according to the survey of workers in automobile factory may not be effectual to save money and increase profits.
Even assuming the survey is credible, to reduce need for supervisors is not the only factor to increase productivity and save money For one thing, younger workers may have higher work efficiency, while the old workers have behaved clumsily. Therefore, if the printing company reduces the younger employees, the profits in sum would also present a tendency of decline. On the other hand, the average salary of older employees in printing company is probably higher the younger’s', inasmuch as older workers have more experience and are more adept. So the company would afford more money to pay for the extra older workers rather than saving money.
As it stands, the conclusion of this argument is not well reasoned. To make it more logically acceptable, the author would have to demonstrate more detailed investigations with solid facts for appropriate deductions. Such as, the specific amount of investigated workers, concrete circumstance of productivity in the printing company and essential factors would lead to increase productivity and save money.
