Once in production you rarely see engineering changes that effect production. What usually occurs are issues relating to tool ware or customers TGW’s that may force a tooling change.

You and I appear to have different perspectives. I worked on the electronics and software parts of the vehicle. We were less susceptible to tooling wear but still had to deal with parts disruptions due to earthquakes, fires, etc.
In the old days we used to get burned every time we discovered a software bug. The old control modules were potted and used masked ROM. They had to be destroyed if the software bug affected our certification validity. Those events generated a lot of scrap that JIT could have avoided. Things got a lot better when JIT was combined with FLASH memory technology.
