Despite the wealth of literature on requirements engineering, little is known about engineering very generic, innovative and emerging requirements, such as those for cross-sectional information chains. The IKM health project aims at building information chain reference models for the care of patients with chronic wounds, cancer-related pain and back pain. Our question therefore was how to appropriately capture information and process requirements that are both generally applicable and practically useful. To this end, we started with recommendations from clinical guidelines and put them up for discussion in Delphi surveys and expert interviews. Despite the heterogeneity we encountered in all three methods, it was possible to obtain requirements suitable for building reference models. We evaluated three modelling languages and then chose to write the models in UML (class and activity diagrams). On the basis of the current project results, the pros and cons of our approach are discussed.
尽管关于需求工程的文献众多，但对于设计非常通用、创新和新兴的需求，如跨部门信息链的需求，我们却知之甚少。IKM健康项目旨在为慢性伤口、癌症相关疼痛和背痛患者的护理建立信息链参考模型。因此，我们的问题是如何恰当地获取既普遍适用又切实有用的信息和处理需求。为此，我们从临床指南的建议入手，并在德尔菲调查和专家访谈中进行讨论。尽管我们在这三种方法中都遇到了异质性，但仍有可能获得适合构建参考模型的需求。我们评估了三种建模语言，然后选择用UML（类图和活动图）编写模型。基于当前项目结果，讨论了我们方法的优缺点。
