Software Testing: QA or QC

In every other field the testing of products is called Quality Control (QC) but in IT (software especially, it is called QA (Quality Assurance).    This is a historic anomaly.

This process check was quality assurance (QA).  Often those doing the checking were not skilled programmers so could not actually test the code (QC) to see if it would work.

Eventually, programmers got used to typing their own code into PCs and the QA team became mainly system testers.
