Don't play games and try to put words in my mouth. I said what I said.So, I take it you would accept a 25 year internal audit schedule then.
Time is not the determining factor. I would not use time as the determining factor. I would use what the damn standard says are the determining factors. If as the auditor I wanted to use time as a determining factor, I would make that a contractual requirement in my contract with the auditee.
Why is this so damn hard?
