The auditors are looking to se what people are doing and, as stated above, it s pretty simple stuff. After a registration audit, I have heard every time, from many people, the same thing:
Is that all there is to it?
If you re prepared, when the test is over - Yes. Yes. Yes. That s all there is to it.
What Will The Auditors Do?
The auditors will look at written procedures and policies (verification).
The auditors will then look at how people in the company do things. They will look to make sure each person is following written procedures and policies (validation).
They will look at records to ensure everyone is properly completing paperwork (Examples would be SPC charts and check lists which need to be initialed and dated).
They will look to make sure everyone is properly trained to do their job.
