The service auditor looks into what each deviation found was and why it happened, and then decides which of these applies: the deviations fall within the rate expected and are acceptable, so the tests support a conclusion that the control operated effectively; further tests, of this control or of others, are needed before concluding on the related control objective; or the tests show that, over the whole period, the control failed to operate effectively.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
