"Furniture Depot employed our internet advertising company to help. Since then its sales increased by 10% over last year's totals. Furniture Depot's success demonstrates how using our internet services can increase your profitability."
In the argument, the author uses cause and effect to concludes that any business can increase its profitability by using Internet advertising as used by Furniture Depot. He bases his conclusion on single evidence. And assumes certain aspects in his conclusion. His assumptions are flawed. A few include.
Primarily, the author ignores all others factors that could have effected profitability of Furniture Depot. There might be many other factors in addition to Internet advertisement that would have led to increase in profitability of the firm. For instance reduction in computation might be the major reason for increase in the profit.
Secondly, the author uses data in percentage form to prove his point. Percentage data would may give misleading picture without any information about the initial fingers. For instance an increase profit from $ 1000 to $ 1100 is a 10% increase but a $ 100 increase might not be very substantial for large business firms.
Lastly, the author in his conclusion misses the fact that every business has its own requirements and strongly concludes that the same strategy can be successful for all type of business firms. For example the advertisement strategy for a FMCG product will be completely different from that of Furniture Depot.
The author’s argument could have been justified if the author has provided some more statistical data to show the increase in profitability. Furthermore the author could have taken other factors that can affect profitability into consideration. Moreover a reduced force on the conclusion might have made the argument more acceptable.
Therefore based on the reasons cited above the argument is ill constructed and flawed.
