The following appeared in a memo from the vice president of marketing at Dura-Sock, Inc.
"A recent study of our customers suggests that our company is wasting the money it spends on its patented Endure manufacturing process, which ensures that our socks are strong enough to last for two years. We have always advertised our use of the Endure process, but the new study shows that despite our socks' durability, our average customer actually purchases new Dura-Socks every three months. Furthermore, our customers surveyed in our largest market, northeastern United States cities, say that they most value Dura-Socks' stylish appearance and availability in many colors. These findings suggest that we can increase our profits by discontinuing use of the Endure manufacturing process."
Write a response in which you examine the stated and/or unstated assumptions of the argument. Be sure to explain how the argument depends on these assumptions and what the implications are for the argument if the assumptions prove unwarranted.
This argument recommends discontinuing the use of a specific manufacturing process step citing the customer preferences and purchase frequency of product. While it may merit the company to discontinue the process, this argument from the vice president is rife with several assumptions.
Vice-President mentions that use of Endure manufacturing process is advertised to customers. However, it is not clear if the advertisement quantified the durability. Due to its terse nature, advertisement might have just highlighted that these stocks stay usable on a relative scale when compared with that of competitor products.
Building on the durability aspect, author connects the knowledge of customers to frequency of their socks purchase. Higher demand may be attributed to sudden burst in population because of industrial revolution. Or, the purchase frequency might be skewed without the consideration of seasonal demands. Its normal to assume that winters may demand more socks. Increase of sales is what a company should dream of and this is not a convincing reason to reduce product quality.
Author cites a survey to highlight customer preference of style over durability but does not support the argument with details of this survey. Along with the sampling of users from largest market, its also important to understand how many customers participated and if the survey was conducted across seasons. The scope and validity of the survey is thus dubious to lead to any conclusion.
Most importantly, its unclear how much profit would accrue if the Endure manufacturing process was discontinued. The process might be a low cost step and hence could be a good value addition for the sell-ability of socks and to differentiate from its customers. In fact, removing this differentiation may actually lead to reduced profits if the market share swings towards the competitor.
Author's intention to increase the profits through the discontinuation of Endure manufacturing process would have been stronger with data on the ROI (Return of Investment) over a period of time across its markets. The arguments proposing the termination of a process step are thus too weak to be acceptable.
