karrank,
I take your point; but were the Hazards identified and then correctly mitigated?
This process has avoided identifying hazards unless there is a difference in the detail of each procedure.
The problem with NAS so far, is that most of the 'same procedures' are introduced into a different environment, (which is a difference) then they're not assessed because they are the same; each change should be assessed and mitigated correctly.
