设计科学的效度 (Validity in Design Science)

研究人员必须确保其工作产生的知识的主张是有效的。然而，在设计科学中，效度既没有得到很好的理解，也没有得到一致的确立，因为设计科学涉及开发和评估用于解决问题的构件（模型、方法、实例和理论）。因此，证明和传达关于构件的知识主张的效度是一项挑战。本文定义了设计科学中的效度，并推导出设计科学效度框架和应用该框架的过程模型。该框架包括三种高级主张和效度类型——标准、因果和环境——以及效度子类型。该框架指导研究人员将效度考虑因素整合到采用设计科学的项目中，并为日益增多的设计科学方法研究体系做出了贡献。它还提供了一种系统的方法来阐明和验证设计科学项目的知识主张。我们将该框架应用于现有研究的实例，然后用它来证明关于框架本身的知识主张的效度。

Abstract — Researchers must ensure that the claims about the knowledge produced by their work are valid. However, validity is neither well-understood nor consistently established in design science, which involves the development and evaluation of artifacts (models, methods, instantiations, and theories) to solve problems. As a result, it is challenging to demonstrate and communicate the validity of knowledge claims about artifacts. This paper defines validity in design science and derives the Design Science Validity Framework and a process model for applying it. The framework comprises three high-level claim and validity types—criterion, causal, and context—as well as validity subtypes. The framework guides researchers in integrating validity considerations into projects employing design science and contributes to the growing body of research on design science methodology. It also provides a systematic way to articulate and validate the knowledge claims of design science projects. We apply the framework to examples from existing research and then use it to demonstrate the validity of knowledge claims about the framework itself.
