I submitted my MMOG to Ford this year with supporting objective evidence. This was a change from previous years and was specifically required by the updated MMOG document. Here is an excerpt from the MMOG:
Ø Completing the EvaluationWhen carrying out an assessment, the assessor should take into account a number of factors before deciding whether the organization is compliant with a criterion. It is not sufficient to simply determine if there is a process in place that satisfies the condition. The organization should also check that the process is understood and adhered to, and the output of the process is delivering the required or expected outcome on a consistent basis. Objective evidence that the process is stable and well established in the organization is key.
AND:
Alongside each criterion within the Assessment there is a COMMENT box that should be used to record any information regarding the assessment response. For example, the assessor could record details of any objective evidence, the reason for a non-compliance, or any other information that might assist in understanding the operating conditions at the time of the assessment. It is a mandatory requirement to record in the COMMENT box the reasons why a criterion is deemed Non Applicable. The content of the COMMENT box is transferred automatically to the Gap Analysis worksheet.
I didn't include additional documents with the submission, but I did include comments/objective evidence for every requirement.
My submission was approved by our Ford STA.
