The quality profession

This question is like asking what is communication's role in civilization - both concepts are very broad. It may be possible to somewhat explain in simple terms, but no guarantee a simple answer will deliver clear understanding of broad concepts.

This sounds like an essay question. Who is the audience and what is the context of the question?
