Each change request is analysed for its impact on functional safety, identifying the affected work products, the safety activities to be repeated and the confirmation measures to be renewed (part 2 6.4.9 note 6 requires confirmation measures to be repeated or supplemented after a change). This sits in clause 8, whose stated aim, per the SGS quotation, is that every change to safety-related work products, items or elements is analysed and kept under control over the whole lifecycle. Requirement text not held.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
