Validation of design methods is a challenge in design research, as there is a lack of common methodology. This contribution investigates how validation of design methods is currently conducted in order to clarify this issue and identify approaches that might be suitable as best practices. A mixed-methods literature study including the years 2010–2020 is conducted. Systematic mapping structures the identified literature in an overview. The following state-of-the-art review focuses on challenges in validation and on how researchers address them. The overview of 54 identified studies shows a preponderance of non-comparative studies conducted in laboratory environment. Challenges arising in conducting experiments and field studies are caused by a lack of common metrics and established study designs. In success evaluation, the challenge is to objectively measure the effects of method application on the design outcome. Based on the identified examples, possible strategies to overcome the challenges are proposed.

由于缺乏通用的方法论，设计方法的验证是设计研究中的一个挑战。此贡献调查了当前如何进行设计方法的验证，以澄清此问题并确定可能适合作为最佳实践的方法。进行了包括 2010-2020 年的混合方法文献研究。系统映射以概览方式构建已识别的文献。以下最先进的评论侧重于验证中的挑战以及研究人员如何解决这些挑战。对 54 项已确定研究的概述表明，在实验室环境中进行的非比较研究占优势。在进行实验和实地研究时遇到的挑战是由于缺乏通用指标和既定的研究设计。在成功评估中，挑战在于客观地衡量方法应用对设计结果的影响。根据确定的例子，提出了克服挑战的可能策略。
