Purchasing procedures make sure that bought-in raw materials, other materials and services with a bearing on food safety satisfy the organization's own requirements. If a food safety relevant process is subcontracted, the organization keeps control over it by telling the subcontractor how it must be controlled, typically through specifications and contract clauses.
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.
