Question: What’s the difference between QA and QC?
Answer 1: QA (Quality Assurance) is when you constantly check – and debug – your software project through the multiple stages of software development whereas QC (Quality Control) is when you check and debug your entire project at the very end of the software development process.
For (most) bigger or even small home projects I would recommend QA because if you run into a problem sooner it’s usually a lot easier to fix than waiting to the very end – when things can get really messy! （Author: Brad Turner From: Quora）
QC: Make sure you do things right
QA: Make sure you do the right things
I keep seeing people worrying too much about the difference between QA, QC. The fact is that it doesn’t matter if you can’t distinguish between the two especially if you are new in software testing（Author: Thanh Huynh From: Quora）
is the point at which you continually check – and troubleshoot – your product venture through the various phases of programming advancement while QC (Quality Control) is the point at which you check and investigate your whole task at the very end of the product improvement process.
For (most) greater or even little home ventures I would suggest QA on the grounds that on the off chance that you keep running into an issue sooner it’s generally a considerable measure less demanding to settle than holding up to the very end – when things can get truly untidy! （Author: Hitek Schools From: Quora）
