Here are things that I understand about the difference in QA and QC.
QA is process-oriented, aiming to build quality into the product from the start, whereas QC is product-oriented, ensuring the finished product meets the required standards.
QA takes place during the design and development stages, while QC happens after or during production.
The goal of QA is to prevent defects, while QC focuses on identifying and correcting them.
QA relies on audits, process reviews, and regulatory checks, whereas QC uses testing, inspections, and statistical analysis.
Switching between the two can be possible, but it might depend on the skills you’ve developed. Moving from QC to QA might be trickier since QA requires a deeper understanding of systems and regulations, whereas moving from QA to QC could be a bit easier, as it’s more hands-on and practical. It really depends on your background and how much experience you have in both areas.
QA and QC often work together, even in the same departments. QA established the baseline requirements, and even makes a lot of the SOP's. QC does many of the stability tests, and statistical analysis to make sure products and procedures are in conformance. Although there is that distinction, the tasks also often overlapped between roles.
Quality Control often works with production, and some have Quality Inspector in their title. Their training is often related to procedures in their position related to Non-Conformance Reports and CAPA. The QA personnel need training to get a better systems based understanding of a company's QMS.
