| The fact that superior service can generate a competitive advantage for a company does not mean that every attempt at improving service will create such an advantage. Investments in service, like those in production and distribution, must be balanced against other types of investments on the basis of direct, tangible benefits such as cost reduction and increased revenues. If a company is already effectively on a par with its competitors because it provides service that avoids a damaging reputation and keeps customers from leaving at an unacceptable rate, then investment in higher service levels may be wasted, since service is a deciding factor for customers only in extreme situations. This truth was not apparent to managers of one regional bank, which failed to improve its competitive position despite its investment in reducing the time a customer had to wait for a teller. The bank managers did not recognize the level of customer inertia in the consumer banking industry that arises from the inconvenience of switching banks. Nor did they analyze their service improvement to determine whether it would attract new customers by producing a new standard of service that would excite customers or by proving difficult for competitors to copy. The only merit of the improvement was that it could easily be described to customers. The passage suggests that bank managers failed to consider whether or not the service improvement mentioned in ine18-20 (A)was too complicated to be easily described to prospective customers (B)made ameasurable change in the experiences of customers in the bank’s offices (C)could be sustained if the number of customers increased significantly (D)was an innovation that competing banks could have imitated (E)was adequate to bring the bank’s general level of service to a level that was comparable with that of its competitors 正确答案是D 划线部分已经highlight，看了og的解释也不明白，请教各位NN，我一点也没看出来和其他竞争银行模仿他们行为有什么关系啊  |
