Each change is initiated by a change request that identifies the work products affected, the reason and the type of change, with a unique identifier. This sits in clause 8, whose stated aim is that every change to safety-related work products, items or elements is analysed and kept under control over the whole lifecycle. See the official text for the full requirement.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
