I know quite well the difference between Quality Control and Quality Assurance. However (maybe as I am not a native speaker) I have issues with understanding of QC as defined by ISO 9000:
QC - 'part of quality management focused on fulfilling quality requirements'.
-Monitoring of processes to ensure the output is of quality -Activities to correct discrepancies
I cannot see how this is fulfilling quality requirements? I would say that only development actually can fulfill the requirement, QC only checks the conformance but on its own cannot fulfill anything. Or is this what it means - that it is concerned with whether the requirements are met?
