The BIA process should span the entire BCMS scope, which the organization is expected to have already set and documented by reference to its products and services. Its outcomes may lead the organization to revisit that scope, bringing products and services in or taking them out. As a first step the organization should rank every product and service within scope, internal strategic services among them where relevant, and deal with the highest priorities before the rest.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
