>They make hardware changes every day/week/month. How are they sourcing parts and integrating them into the manufacturing process "every day"? This seems like an SV understanding of manufacturing; Tesla may be more agile than the average auto OEM, but there is still a complex procurement prcoess that requires lead time, as well as spare parts for fleet repair and maintenance. Do you have an example of a piece of hardware they are swapping every day, week or month? Maybe this is why they have a hard time servicing their cars. |

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.

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
https://www.thestreet.com/tesla/news/munro-tesla-model-y-oct...
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.

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.
