Trying to be less wrong
It’s hard to meaningfully compare to an industry standard because Tesla does a lot of stuff normally delegated to suppliers including seats and battery cells.It takes 18hrs for Toyota to build a car which is considered to be the most efficient factory in the world.
I would love a SAY question during earnings to be "can you please share to us how many hrs it takes Tesla to build a Model Y from beginning to end at Giga Texas, and what is the ultimate goal you guys are working toward? How does this compared to industry standard?"
I would love to know the answer to this and it will put "but Tesla is a car company" to rest. The length of time it takes to build a car has a direct correlation to gross margins. This is the most important question to ask, especially about the end goal.
Total flow time is also affected by whether industrial processes can be run in parallel or if they must be in series, but that doesn’t have much impact on production capacity or unit cost.
Related but more informative questions for a manufacturing line are what is the cycle time and how many total labor hours are required per unit.
