信息系统价值的线性模型是信息属性的函数，通过让两家公司的经理对属性的重要性、每个属性的不同级别产生的满意度水平以及整个系统的整体价值进行评估，对信息系统价值的线性模型进行了实证研究。结果表明，该模型在信息系统设计中具有一定的实用价值。研究还表明，在线性模型中，按顺序排序的属性与按区间排序的属性一样有效。由于序数度量更容易获得，这表明“线性序数”模型可能是量化信息系统价值的最实用的方法。
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.
