Proceedings of the 32nd European Safety and Reliability Conference (ESREL 2022). 2022, S06-02-017, 2055-2062. 10.3850/978-981-18-5183-4_S06-02-017-cdSammendrag
The railway industry is undergoing modernization and development with increasing use of new technology and digitalisation. In addition to physical security requirements, systems need to be secured against cyberattacks from outsiders. In addition, there are other quality requirements like scalability, reliability, availability, and sustainability that need attention. This paper presents results from testing the quality triage method, which has its origin from software development, on railway projects. The quality triage method aims to balance several quality requirements for decision making in development projects. Cybersecurity is an example of these quality requirements. A discussion of cost elements and benefits from applying the method within the railway domain has been outlined. As a main conclusion, the authors see new opportunities of addressing quality requirements more explicitly in projects by applying the quality triage approach to railway projects.
