So here on this slide we have the difference between QC which is Quality Control and QA which is Quality 2
Assurance. 3
So if you look at the first one the focus of Quality Control is on the product and that's what we were 4
talking when we looked at the definition also. 5
The focus was on the product, The focus was on getting the right input. 6
The focus was on getting the production done right and the focus was on making sure that the finished 7
product is good meets the requirement. 8
So in all that chain the focus was on the product whereas when it comes to Quality Assurance. 9
The focus is on process. 10
So here the intent is that if the processes are being done in the right way the product will be right. 11
In QA the focus is on the process. Coming to QC, QC is considered to be a reactive. 12
Q is considered to be pro-active. 13
So in QC you look at the product if you see the problem then you attend to that problem and make sure 14
that the problem is not repeated. 15
So basically all these activities happen once you have a problem whereas in QA you make sure beforehand 16
that your processes are set so that you don't get into trouble. 17
So that's the focus of QA being proactive. QC is the line function and QA is the staff function. 18
So when you say line function and the staff function, line function is something which is let's say 19
in case of production. 20
These people QC people report to production group. 21
Here the focus is on production. 22
QC is working in the shop. 23
QA is a staff function. 24
This is a support function. 25
The next one here is that the focus of QC is on finding defect whereas the focus of QA is on preventing 26
defects This is somewhat similar to what we said when we said that reactive and proactive. Coming to 27
this fifth line where we said that QC is related to Testing and QA is related to Quality audits. 28
So the tools used for Quality Control is the testing, testing is the tool for Quality Control and audits 29
are the tools for Quality Assurance function. 30
So this slide gives you a difference between these two aspects of Quality, Quality Control and Quality 31
Assurance. 32
Having understood this now let's move to the next thing which is quality management system.
