Comments on "Price and Value of Decision Support Systems"
批评了Pieptea和Anderson（1987）关于决策支持系统成本效益的框架，指出其概念缺陷和逻辑矛盾，认为无形效益与价值价格差距的关系被错误解读。
Pieptea and Anderson's (1987) article promised to reconcile the conflicting approaches in cost-benefits literature on DSS. However, we find several weaknesses in their conceptual framework and their use of Simon's phases of decision making. We argue that the true relationship between the phases of decision making and the intangibility of DSS benefits is exactly the opposite of what Pieptea and Anderson claim it to be. In the construction of Dimension II, Pieptea and Anderson unjustifiably collapse four criteria into one. Furthermore, some of their criteria appear in the definitions of both the dimensions of their framework. They equate the intangibility of benefits with "value-price gap," which could mislead managers into believing that all DSS with high degree of intangibility are ipso facto justified.
