Trying not to get into a document control discussion here, but in short proces descriptions define the why (the company's objectives), procedures the who does what, when.
As the audit question mostly is "Do you have a procudere for...." I have put them together, which is actualy incorrect, but served the example I hope.

Yes, I understand it is off-topic. But after a few days have gone by and there's no further input from the original poster, I can't see a problem in continuing a discussion.
I thought about your response for quite a while, and it left me more confused. I certainly wouldn't describe a discussion of the difference between a process description and a procedure as about
document control - which is a quite separate issue, to me in any case.
I think we have extremely different views here; I really cannot accept your definition of a process descriptions as something that would 'define the why (the company's objectives)'. A process description is ... a description of a process, or a model or a flowchart or diagram or map. But 'define the
why'? I don't understand.
