Said it once, will say it again. Elon needs to provide stochastic simulations of his production line with realistic failure rates of each component. Understand where those high failures are and build in the same redundancy he does to the Model 3's frame.

Is it just failure rates, though? He's said in the past a lot of it that they have 30,000 parts and a massive number of suppliers to rely on. For instance, with the model X doors, there were substantial delays because their contractor said it could be done hydraulically, but it wasn't completed, so then Tesla did it itself with electromechanical systems. To me, that massive delay wouldn't be captured by your production line simulation.

  some youtube video about the latest conf call said they redesigned the parts to reduce and streamline everything.. but anyway your poind holds

  Managing suppliers/supply chains, testing their designs, integrating their designs into yours is the major challenge for a manufacturer, IMO. It goes well beyond the challenge of testing and verifying elements of your own design.

>the same redundancy he does to the Model 3's frame. If Ray Charles tried to shoot the broad side of the barn he's probably hit the pinch welds on a Tesla in the next town over. Superfluous part numbers (like their multi-piece wheel wells) and material excess is the kind of redundancy the Model 3 has the most of. Tesla doesn't make efficiently designed cars any more than Juicero made efficient juicers. Tesla has carved out a market niche that they won't easily be unseated from but efficient design is not that niche. You can simulate and model all you want. If you don't have the expertise in house you won't be able to get much value out of it.

  I agree, but for context, remember that the other car companies have been fine-tuning their supply chain processes for the last 100 years. Telsa is by no means a GM or Ford in and as far as supply chain refinements. I imagine GM or Ford wish they had the popularity and customer desire that Telsa has, and we've been witnessing the start of their forte into the mass production and no matter how many experts you throw at a difficult problem, you still need to refine and mature your processes.
