Choosing a supplier includes assessing its ability to develop, and where relevant manufacture, items and elements of similar complexity and ASIL to the standard; the criteria may draw on its quality management system, past delivery and quality record, the functional safety capability it demonstrates in its bid, earlier functional safety assessment results (part 2 6.4.12) and the views of the vehicle maker's development, production, quality and logistics functions where they touch functional safety.
This control maps to 2 controls across 2 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 2 it maps to, and the evidence behind each claim, over MCP and REST.
