> How are they sourcing parts and integrating them into the manufacturing process "every day
They know by VIN exactly what parts go in what car.
That said, the coding equivalent is that they make interfaces - and swap out interfaces. You can make a LOT of changes at the implementation level, that do not change an interface.
> Do you have an example of a piece of hardware they are swapping every day, week or month?
Sure, they are swapping the entire body caste machine from ~20 parts down to 1..

went live this week I believe, while they are actively cranking out thousands of model Ys per day.
Another example - the octovalve - a very special decide that lets heat and cold get shared 8 ways as needed between motors / battery / and cabin is a huge part of the model Y. According to a teardown

the valve has had 13 changes in the 6 months the car has been in production. 13! In a single part that is the size of a small backpack.
> Maybe this is why they have a hard time servicing their cars.
This has not been my experience at all. I think QC is a little low on brand new cars during rush season, but service has been top notch. Make sure you aren't relying on stories from 2016.
