上下文。在许多应用领域中，关键系统必须符合安全标准。这包括以工件的形式收集安全证据，例如安全分析、系统规范和测试结果。这些工件可以在系统的生命周期中发展，因此需要进行变更影响分析，以保证系统的安全性和遵从性不会受到损害。目标。我们的目标是为如何在实践中解决安全证据变化影响分析提供新的见解。尽管在变化影响分析和安全证据管理方面进行了广泛的研究，但关于这一活动的知识仍然有限。方法。我们对安全证据变化影响分析的处理情况、使用的工具支持以及面临的挑战进行了行业调查。结果。我们获得了来自16个应用领域、28个国家和47个安全标准的97个有效回复。被调查者在系统开发过程中经常执行安全证据变化影响分析，从系统规格，完全手动。没有商业变更影响分析工具被报告用于所有的工件类型，并且工具支持不足是最常见的挑战。结论。结果表明，作为安全证据的不同人工制品类型是共同进化的。此外，安全案例的演变可能需要更好的管理，安全证据变化影响分析的自动化水平较低，实践状态可以从20多个改进领域中受益。
Context. In many application domains, critical systems must comply with safety standards. This involves gathering safety evidence in the form of artefacts such as safety analyses, system specifications, and testing results. These artefacts can evolve during a system's lifecycle, creating a need for change impact analysis to guarantee that system safety and compliance are not jeopardised. Objective. We aim to provide new insights into how safety evidence change impact analysis is addressed in practice. The knowledge about this activity is limited despite the extensive research that has been conducted on change impact analysis and on safety evidence management. Method. We conducted an industrial survey on the circumstances under which safety evidence change impact analysis is addressed, the tool support used, and the challenges faced. Results. We obtained 97 valid responses representing 16 application domains, 28 countries, and 47 safety standards. The respondents had most often performed safety evidence change impact analysis during system development, from system specifications, and fully manually. No commercial change impact analysis tool was reported as used for all artefact types and insufficient tool support was the most frequent challenge. Conclusion. The results suggest that the different artefact types used as safety evidence co-evolve. In addition, the evolution of safety cases should probably be better managed, the level of automation in safety evidence change impact analysis is low, and the state of the practice can benefit from over 20 improvement areas.
