Assuming that you are only looking at the QA aspect, be careful not to conflate QA with QC. It’s a common mistake. QC concerns testing, inspection, detecting defects, and stopping defectives from moving to the next step in the process. QA, on the other hand, concerns assuring management and everyone else involved that procedures and standards are followed and analyzes how well they’re working. In the end-to-end supply chain QC looks at the quality of the inputs and outputs while QA looks at the quality of the process, including QC.
By “QDF” I assume you mean “QFD” (Quality Function Deployment). You can find many examples but the bottom line is you have to do it yourself for your process. It’s a rigorous exercise that requires training and lots of reliable data. In my experience they often end up using assumptions and are more often misleading rather than useful, after a great deal of work. But if you want or are required to go there, here’s a starting point: https://asq.org/quality-resources/qfd-quality-function-deployment
I would not do a QFD without a software tool since doing it on paper is really, really tedious and time-consuming. And doing it yourself in Excel or other general-purpose software can be even harder, and very error-prone. You can find free QFD software and templates on the internet.
