The manufacturer demonstrates that its CSMS applies to the development phase (before the type is approved), the production phase (while the type is produced) and the post-production phase (from end of production until no vehicle of the type remains operational). The Interpretation Document: procedures must cover all three phases, may include processes for end of support and for disconnecting non-mandatory functions, and 7.2.2.2 and 7.2.2.4 apply in every phase; ISO/SAE 21434 clauses 9 to 11 evidence development, clause 12 production and clauses 8, 13 and 14 post-production.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
