What is the difference between QA & QC ?

Answer Posted / duttasj

QA stands for Quality Assurance and is overall responsible
for ensuring quality of the product and related compliance
activities (GMP, documentation etc) that can have an impact
on the product quality.

QC stands for Quality Control and is specifically involved
in analysis of sampling of raw and packaging materials and
their analysis, analysis of finished products and
preparation of Certificate of Analysis. They are also
involved in performing analytical method validation
activitites, equipment qualification and calibration.
In some organizations QC plays an additional role of
performing stability analysis.
