Argument 117
The following is a memo from the business manager of Valu-Mart stores.
"Over 70 percent of the respondents to a recent survey reported that they are required to take more work home with them from the workplace than they were in the past. Since Valu-Mart has not seen impressive sales in its office-supply departments in the past, we should take advantage of this work-at-home trend by increasing at all Valu-Mart stores the stock of home office machines such as printers, small copy machines, paper shredders, and fax machines. We will also increase stock of office supplies such as paper, pens, and staplers. With these changes, our office-supply departments will become the most profitable component of our stores."
====================================================================
1. To begin with, the validity of survey is doubtful.
2. The arguer assumes that those who work at home need the home office machines and office supplies.
3. The manager neglects other factors to influence the profits of office-supply departments.
====================================================================
In this memo, the manager recommends that we should increase the stock of home office machines and office supplies at all Valu-Mart stores. To support his conclusion, he cites a resent survey that most of the respondents say that they are requested to take more work at home. Moreover, he points out such action will increase profits in office-supply departments. As it stands, the argument suffers from several critical flaws as follows.
To begin with, the validity of survey is doubtful in two respects. First, lacking information about the number of people surveyed and the number of respondents, it is just as likely that only 50 persons responded while 500 individuals were surveyed. Second, we are not informed about the age groups and the occupations of the people. Absent such information, perhaps the age of respondents focus on a certain group but others are seldom required to work at home, or perhaps certain kind of occupation such as technicians needs the extra works while others don't need. Only ruling out such possibilities, can we believe that the survey is persuasive and credible.
In addition, assumption that those who work at home need the home office machines and office supplies helps the manager to conclude that we should increase the stock at all Valu-Mart. But the manager fails to provide any evidence to substantiate his assumption. It is possible that people working at home use E-mail or Microsoft Word to write documents or send messages and there is no need for them to buy any extra machines or papers. To better convince us, the author should supply the information about the necessity of the increasing stock.
Moreover, the manager neglects other factors influencing the profits of office-supply departments. Such factors, as economy environment, costs of the office-supply transportation, and the price of machines may greatly affect the profits. Maybe the price in Valu-Mart stores is much higher than in other stores, maybe the costs of transportation increase rapidly due to the shortage of vehicles, or maybe the economy is in recession that individuals have little extra money to buy office machines. Overlooking such possibilities probably influencing the profits, how can the manager make a confident conclusion that only increasing the stock in stores could bring more profits?
In summary, the argument is not persuasive as it stands. To make it more convincing, the manager should provide more information about the validity of the survey and factors affecting the profits of office-supply departments. To better evaluate the recommendation, we would need more evidence regarding the cause-and-effect relationship between working at home and buying home-office machines and supplies. |
