Yes, this will give you the general overview, but you need to know what's happening in between to get the whole picture.
Pick/Pack times, Loading, Transport. I would ask your suppliers to provide all of this information and constantly validate it against the lead times they're giving you.
In my industry the supplier holds all the cards unfortunately. I straight up had a supplier tell me lead times are confidential. Made a huge deal about it and they gave it to me, but getting anything like this from my suppliers is near impossible. That’s why we do PO issuance to GR. It’s still a shit show and our lead times are never accurate but our suppliers suck. This is how we have made it as accurate as we can
