In a lot of "traditional" industries, because you "can't touch" or put it into inventory software is not seen as important "it is just there at the end". Furthermore there is a huge disconnect, because they don't understand software... everything "can later be fixed in software", the procurement department is incentivized to buy the cheapest hardware/chips they can get and you as a software developer are never asked if the requirements can be implemented on the hardware they procure leading to delays because you have to fit all the promised features into a shitty 5cent cheaper hardware and if it fails it's the software departments fault (looks like this is a bit the case in CARIAD when reading some german forums/articles).
