A Modeling Approach to Evaluating Strategic Uses of Information Technology
针对传统静态成本收益法难以评估信息技术战略效益的问题，构建了一个模型帮助管理者权衡先发优势与成本下降的延迟激励，选择最佳实施时机，并以银行业为例比较了区域大行与地方小行的实施时间。
:Traditional static benefit-cost methods were useful when evaluating transaction processing systems. Strategic benefits are more difficult to evaluate, since they involve dynamic interactions between customers, suppliers, and rivals. In an attempt to gain a competitive advantage, there is a strong incentive to be the first implementor of new technology. However, information technology (IT) costs decline over time, so there is an incentive to delay implementation. A model is developed that enables managers to evaluate this trade-off and choose the best implementation time. The model emphasizes competition between large firms in a regional (or national) market, interacting with firms in a local market. The model is illustrated with an application to the banking industry. It compares the implementation times of larger regional banks vis-a-vis smaller local banks, and shows how the banks might use technology to respond to various changes in the banking industry.
