Explanation:
Differences Between QA (Quality Assurance) & QC (Quality Control)

Suppose you are manufacturing Coke. QA would ensure that you have all the right processes in place to manufacture and test the quality of the coke. Like the machines , people, recording mechanism etc. QC is doing the actual testing on finished product. So when the coke bottle is out you do a sample test and it would either pass or fail the Q standards.

So QC is to do with testing and verification after the deliverable is done and QA is before the deliverable is made. Like giving trainings to people, Auditing the process, ensuring everyone understands the process etc are all QA activities.
