Sometimes, someone or some companies misunderstanding between QC and QA. There are two different concepts: QC who controls the quality of product and QA who manages the process to make the process always on track and getting improvement.
But some cases, there are very rare companies, QC and QA play the same role. QC dont do testing, they control developers and and give instruction, consult them to test the product.
How is your company doing? Any sharing is welcome.
