ASSESSING INFORMATION SYSTEM VALUE: AN EXPERIMENTAL STUDY
通过两家公司管理者的实验，验证了基于信息属性的线性模型在信息系统设计中的实用性，并发现顺序排名属性与区间尺度属性效果相当，为量化信息系统价值提供了更简便的方法。
Linear models of information system value that are a function of information attributes are empirically studied by having managers in two firms make assessments of the importance of attributes, the level of satisfaction produced by various levels of each attribute, and the overall value of total systems. The results verify that such models may be quite useful in information system design. It is also shown that ordinally ranked attributes work as well as the interval‐scaled attributes in the linear model. Since ordinal measures are easier to obtain, this suggests that “linear ordinal” models may be the most practical method of quantifying information systems value.
