For us in the AS9100 process approach realm is not the various processes metric's not the true tell of how effective the audit process is?
If the audits of a process are really looking at the process and all its elements proper function the measure used for the process should always be showing improvement as the audit should be identifying any shortcomings that result in poor metrics. This is not even touching on the PM process.
If there is a downward trend to the process measures then it would appear to me that the audits to that point were not effective in some way either by missing a “poor” element of the process or some element of the overall processes of the system.
You would at this point of a degrading metric have to review the applicable audit process to try and determine why they did not identify elements of the process resulting in it's poor performance. You would not have teh person who performed the audit audit themself but have some one else put new fresh eyes on it.
