Why do EN 50126/EN 50128/EN 50129 have better competence management process than ISO26262 ?

ISO 26262's competence management process (part 2) involves identifying necessary competencies for safety-related tasks, ensuring personnel involved in system development and operation have required competencies, and maintaining/improving their competencies over time.

5.4.4 Competence management-Part2 ISO 26262-2018

Organizations can define criteria for sufficient skills, competence, and qualification, but there are no specific definitions for right competencies in a related safety project and their responsibilities, creating a safety culture gap among different responsible parties (safety engineers/testers/SW engineers/product managers).


The railway safety standards EN 50126/EN 50128 provide a structured and comprehensive approach to competence management that can serve as a valuable model for other safety-critical industries. These standards establish an abstraction level of the organization and the independencies between verifiers and validators based on the Safety Integrity Level (SIL) of the system. This means that the level of independence required between verification and validation activities increases as the SIL level of the system increases, ensuring that the safety-critical system is subjected to a sufficient level of scrutiny and oversight. To ensure that all team members have a strong understanding of the relevant safety standards, such as EN 50126, it is important to note that the railway safety standards require all roles involved in the development and operation of the safety-critical system to possess a strong understanding of these standards. Therefore, to provide clarity and prevent confusion, the railway safety standards establish a table defining the responsibilities and competencies required for each role involved in the development and operation of the safety-critical system. This includes roles such as design engineers, verification/validation engineers, product managers, and assessors, among others.

Annex G EN 50126-2:2017 (E)

By outlining the specific responsibilities and competencies required for each role, the standards provide valuable insights and guidance for team members involved in the development and operation of the system. This helps to ensure that all team members understand their roles and responsibilities in the safety-critical system, thereby promoting a culture of safety and responsibility within the organization.
