Hi Burak,
where do you want to measure quality?
One of my IFS customer measures at the following points.
Manufacturing: “raw” product.
Store: random samples.
Purchase: do quality checks on incoming material.

They also do NCR = non conformity reports.
Especially in the area of “customer complaints”

Actually we just started the IFS project and we are in the analysis phase.How can I learn quality management just before starting the project

Dear @burak.cetin 

Here is an IFS document on quality management. There are many ways to control an object in IFS. It may be a purchase order, an inventory part, a manufacturing process and so on…

You need to understand the quality process first And from the document you can see where, when and how to proceed on IFS.

Kind Regards

Thank you, the presentation was very helpful.
