Before it passes requirements to an external provider, the organization makes sure they are adequate. It tells the provider its requirements on: what processes, products and services are to be supplied; how products and services, methods, processes and equipment are approved, and how products and services are released; competence, including any qualification staff need; how the provider will interact with the organization; how the organization will control and monitor the provider's performance; and any verification or validation that the organization, or its customer, plans to carry out on the provider's premises.
This control maps to 6 controls across 6 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 6 it maps to, and the evidence behind each claim, over MCP and REST.
