To evaluate Use Case Maps (UCMs) as a technique for Requirements Engineering (RE) in the development of information systems with functions for spatial analyses in inter-organizational public health settings.
In this study, Participatory Action Research (PAR) is used to explore the UCM notation for requirements elicitation and to gather the opinions of the users. The Delphi technique is used to reach consensus in the construction of UCMs.
The results show that UCMs can provide a visualization of the system's functionality and in combination with PAR provide a sound basis for gathering requirements in inter-organizational settings. UCMs were found to represent a suitable level for describing the organization and the dynamic flux of information including spatial resolution to all stakeholders. Moreover, by using PAR, the voices of the users and their tacit knowledge is intercepted. Further, UCMs are found useful in generating intuitive requirements by the creation of use cases.
With UCMs and PAR it is possible to study the effects of design changes in the general information display and the spatial resolution in the same context. Both requirements on the information system in general and the functions for spatial analyses are possible to elicit when identifying the different responsibilities and the demands on spatial resolution associated to the actions of each administrative unit. However, the development process of UCM is not well documented and needs further investigation and formulation of guidelines.
评估用例图（UCMs）作为一种需求工程（RE）技术，用于开发具有组织间公共卫生环境空间分析功能的信息系统。
在本研究中，参与式行动研究（PAR）用于探索用于需求 elicitation 的 UCM 表示法，并收集用户的意见。德尔菲技术用于在构建 UCMs 时达成共识。
结果表明，UCMs 可以提供系统功能的可视化，并与 PAR 相结合，为在组织间环境中收集需求提供坚实的基础。发现 UCMs 代表了一个合适的级别，用于向所有利益相关者描述组织和包括空间分辨率在内的信息动态流动。此外，通过使用 PAR，用户的声音及其隐性知识被截取。此外，发现 UCMs 通过创建用例在生成直观需求方面很有用。
使用 UCMs 和 PAR，可以在相同背景下研究一般信息显示和空间分辨率方面设计变更的影响。在确定每个行政单位的不同职责以及与行动相关的空间分辨率要求时，既可以引出对信息系统的一般要求，也可以引出空间分析功能的要求。然而，UCM 的开发过程记录不完善，需要进一步调查并制定指导方针。
