#Rework

Tesla keeps insisting it’s going to show the automotive industry how to do things differently. The company’s make-or-break Model 3 was put into production without any pilot assembly or validation prototypes. Tesla is also more vertically integrated than traditional automakers these days. It owns its own stores and it makes many of its own parts. So far, with the EV maker as of yet unable to really get mass production underway on the new sedan, the jury is out on Tesla’s strategies.

CNBC now reports current and former Tesla workers saying almost half of the parts made at or produced for the EV startup’s Fremont, California assembly plant don’t meet production standards, forcing rework and end-of-line repairs, as well as impairing morale in the facility.

This raises the question of whether Tesla will be able to mass-produce vehicles in the quantities associated with automotive mass production: hundreds of thousands of vehicles per year. Tesla needs to be able to build and sell its Model 3 at those numbers to be a viable firm.
