This doesn't come through in most of what you've written in this thread. In fact, rather the reverse.
What kinds of organisations are you auditing? In what fields? What sizes and types?
I can maybe believe a very very small organisation with a very, very low staff turnover and a very, very simple system (one process say)
might have a very low need for written procedures. Or maybe perhaps an organisation with a very high degree of built-in IT/automation.
Maybe. (But then, in the latter case, I'd see that the IT/automation was in fact instead of written procedures - ie, the procedure/process was defined and built-in.
But you're saying you see it
frequently and
very often.
I asked several auditors whose opinion I respect, and all found it quite an unusual idea, and agreed that they would (if they came across it) consider it definitely far from 'normal'.
Seems to me to be heading straight along the path of 'we know what we're doing, and once you've worked here for a while you'll know too', which isn't what I expect from a sound QMS.
This must be one of the most responded to topics, which has explored all kinds of directions and wandered far from the OPs query. Interesting.
