Thank you in advance!
The following appeared in a memorandum from the business department of the Apogee Company:
"When the Apogee Company had all its operations in one location, it was more profitable than it is today. Therefore, the Apogee Company should close down its field offices and conduct all its operations from a single location. Such centralization would improve profitability by cutting costs and helping the company maintain better supervision of all employees."
Discuss how well reasoned ... etc.
My essay:
The argument that the Apogee Company should shut down its field offices and centralize its business operations in order to improve profitability is extremely flawed because it omits some important factors, other than location, that impact on profitability. The sole reason that the Company used to gain more profit before, when it was located at one place than today, when decentralized does not constitute a logical argument in favor of centralization.
Firstly, the argument falsely assumes that the profit of the Apogee Company decreased over time solely because it made a decision to reallocate some of its offices apart from the central office. It fails to consider some other important factors that might lead to the decrease in profit, for example, demand, market conditions or the price for the product might have changed. Probably in the past market conditions were more favorable for the Apogee Company to succeed, for example, the demand was high, very few or even no competitors were on the market. The situation might have changed and the abundance of newly appeared competitors, producing the same type of product made the price of it and, hence, profit to decline.
Secondly, the author erroneously consider that centralization will undoubtly lead to cutting costs, increased profitability and better control over the workers. The opposite might be the case, however. When decentralizing their branches, companies usually seek to lower the labor cost or become closer to the resources they use, or the customers they serve, thus cutting transportation and labor costs, consequently decreasing the price of the product and ultimately leading to increased profit. Therefore, the claim that centralization will certainly increase the profit of the Apogee Company is unsubstantiated.
The argument could be more sound if the author states that for Apogee Company location of its business is the most important factor in determining its profitability and the other external market conditions did not change significantly over the time when it was decentralized. It could also be strengthen by stating that Apogee Company does not seek to use any advantages of decentralization, like reduced transportation or labor costs.
In conclusion, the argument is extremely flawed and comes across as unconvincing and weak since it omitted some factors that must be addressed to conclude that Apogee Company need to centralize its business again to gain more profit. If the author would have considered other factors influencing profitability or the positive sides of decentralization, the argument would be much more convincing.
