Information value chain theory provides a straightforward approach to information system evaluation and design. It first separates the different benefits and costs that might be associated with the use of a given information technology at different stages along a value chain stretching from user interaction to real world outcome. Next, using classical decision theoretic measures such as probabilities and utilities, the resulting value chain can be used to create a profile for a particular technology or technology bundle. Value chain analysis helps focus on the reasons for system implementation success or failure. It also assists in making comparative assessments amongst different solutions, to understand which might be best suited for different clinical contexts.
信息价值链理论为信息系统评估和设计提供了一种直接的方法。它首先将沿着从用户交互到现实世界结果的价值链在不同阶段使用特定信息技术可能产生的不同收益和成本区分开来。接下来,使用概率和效用等经典决策理论度量,由此产生的价值链可用于创建特定技术或技术组合的概况。价值链分析有助于关注系统实施成功或失败的原因。它还有助于对不同解决方案进行比较评估,以了解哪种方案可能最适合不同的临床环境。
