The regional manager of Grocery Town(GT) made at least three logical mistakes in this memo.
Fisrt of all, there is no evidence showing that customer's purchasing habits in Elm City and Oak City is similar enough to compare with each other. The key to the success of one marketing policy is the compliance of the policy to the customer's behavior. Here, the author did not give any trace to prove that people's shopping favors are literally same or even close to in the two cities mentioned. The policy's success in Elm city did not necessarily indicate that this very policy could take effect in Oak City. In addition, when the policy itself could not be proved to be efficient, the manager had no reliance to say that it could help raise the profit of GT in Oak City.
Furthermore, the reasoning supra was based on the hypothesis that GT's "high-low" pricing policy in Elm City is adaptable and successful. However, we cannot find any facts in this statement to prove this assume. Even the statement presented that the profits was soaring, it cannot beat the possibility that if another policy was involved, the profit could be even higher.
Similarly, the case in Elm City itself cannot be said to be wholly trustable. The manager based his reasoning totally on the customer's favor of suddenly low price, which is questionable. Perhaps there were other factors contributing to the rocketing of the profit, for example, the economy environment is getting better or even the customer of Elm City is becoming richer. We cannot conclude the entire reasoning only by this flawed analogy.
Therefore, the main analogy in this statement is unreliable, not to mention the flaws and questions in the evidence itself. The manager needs to provide more reasons to support his change of policy.
