The internet advertising company claims the increase in profitability, demonstrating 10% increase in sales in Furniture Depot.However, there are many holes in the argument that engenders the doubt in assumption and conclusion.There are insufficient details to represent how the success solely based in internet advising company.
At first the assumption, the increase in sales is only due to internet services, is sceptical. There are various other factors in organization success like skilled manpower,quality product, sound vision and so on.Perhaps the increase in sale could be resulted from the quality product rather than via internet services, because in free market people are cognizant about quality.
It isn't clear about how the internet services has overcome the challenges to increase the sales, rather it has only posted that we can increase profitability.People wouldn't simply believe the fact, it can be fabricated and it must state more evidence to support the 10% increase fact.
From the illustration of Furniture Depot, internet services has ensured to increase profitability of business but the nature of business can vary from each other.It isn't clear that what kind of business organization can adapt the services to increase profitability.The advertising service must be specific about the nature of organization to bolster the conclusion.If it is talking about all kind of organization to increase profit then the fallacy is right within the conclusion.
The lack of data,ambiguous assumption and broad conclusion from single organization vitiates the argument. The meticulous attention on such holes is compulsion in order to make people believe the increase in sales is due to internet services.
