Last week we talked about a few common myths regarding Quality Control (see “5 Myths About Quality Control”), but one myth we did not cover was the one about Quality Assurance being the same thing. It’s not uncommon to hear them used interchangeably, and in a closed-loop environment of a large facility, it might not make a difference if everyone agrees to what the definitions are in their environment. But if you ever plan to use outside resources in any way, or want to make sure you are on the same page with suppliers and customers, it might be a good idea to understand the differences and apply them accordingly.
