In this memo, the arguer states that Sartorian should resume its production of its deluxe alpaca overcoats which it discontinued five years ago for the lack of reliable supplies of high-quality wool fabric. And Sartorian will increase its profits because customer will pay more for alpaca overcoats which both Sartorian and its competitors do not produce for a long time. However this argument relies on several dubious assumptions and therefore is not persuasive enough.
In the first place, the arguer said there will be pent-up customer demand. Unfortunately, the arguer did not give any good evidence to prove it. On the one hand, the high price of the deluxe alpaca overcoats may prevent many customers from buying it, for a deluxe alpaca overcoats may be a luxury for most people. On the other hand, there may be something better but even cheaper as a substitute on the market for the customers to purchase.
In the second place, the arguer relies on the fragile assumption that alpaca overcoats will make greater profits than the production the company is selling at the moment. The arguer fail to compare the difference of the profits of alpaca overcoats and other ones, therefore I can not accept the arguer’s point of view.
In addition, assuming new fabric supplier will provide wool fabric of higher quality is also problematic. It is very possible that the new supplier is famous for its lining or other kinds of fabric and even has no wool supply. Thus, the arguer has no reason to say that Sartorian will get better wool fabric from the new supplier.
Moreover, the arguer can not say the price of alpaca overcoats will be higher than that of five years ago because the price of most types of clothing has risen in each of the past five years. It may be true that the price of alpaca has not increased or even decreased for other manufacturers also stopped their production of alpaca overcoats.
All in all, the argument is weak. To strengthen it, the arguer should provide persuasive evidence that customers have strong will to buy alpaca overcoats at a higher price. The arguer must also compare the profits they can get from resuming to produce alpaca overcoats and from going on to manufacture the same kinds of clothing the company is now making. To better assess the recommendation, the ability of the new supplier to provide high quality wool fabric should be proved, too.
