I think "concentrates the mind towards doing things right" is an accurate statement. On the other hand the parent is also correct that it is almost impossible to fail and the requirements are too broad to actually have much effect. The most helpful thing is you get the knowledge and experience of an auditor for a day. Other benefits are having someone make you write your processes down and making it easier to replace people, making sure there is a chart documenting the relationships between the people and to have some language about dealing with customer complaints and defective produce.
