Could someone give a high level overview of how you go from developing a product to manufacturing it? (Engineering processes I guess?)

I’m thinking NPI type jobs. Like working w/ R& D teams and manufacturing teams to establish processes, complete the IQ/OQ/PQs as needed and stuff. I have a job interview coming up soon at a start up and while I haven’t had NPI experience directly, I have experience with manufacturing and product development and all the other skills (like writing protocols for PQ/OQ/IQ but not executing it). I’d like to express my ability to learn and apply it fast on the job due to my prior track record in learning fast (I’ve got a good history of this).
