QA is checking that your output is good. QC is making sure that your output is good before it gets to QA.

Because they single-handedly forced the market against its will to accept electric cars, and we're all better off thanks to it, now that regular car companies decided to join the party too.
Forced? Not really. They made a good battery-powered car and a lot of governments heavily subsidized fully electric cars.

Tesla is doing stamping on-site and in-house. They have to store their in-process inventory somewhere. Toyota tends to push that problem back on their suppliers, demanding small just-in-time deliveries at a steady rate regardless of the optimum batch size for each part. It's an classic problem in manufacturing. Where do you put the in-process inventory? Near where it's made? Near where it's used? Someplace else? What…
I agree with all respect to Jean he's a computer guy and not a Mech Engineer. If Tesla has cheap land and can store locally why not - remember that Japan doesn't have as much land space as the USA has JIT just pushes the costs on to smaller suppliers who a large company can effectively bully in the same way big supermarkets bully framers.
Very similar concept to agile software development — setup everything for rapid iteration.

But don't Japanese companies replicate this setup even when they set up factories the USA?

They made a first quality electric car that both solved the range problem and was sexy enough to attract a wide enough audience, thus for the first time making electric cars a viable and desirable alternative to ICE cars. The subsidies followed.

Etymologically, Quality Control implies some sort of feedback. Quality Assurance merely implies a filter at the end of some process.
Manufacturing ramp-up is exactly this sort of thing. Building by-hand as you work out the process and employ more automation. I'm not sure this is unexpected? As an investor I know full well Tesla has a ticking clock. They must achieve scale before the giants can catch up. People underestimate how god-awful slow the big car makers are. They haven't even come to terms with what Tesla is really doing yet. None have any…
> People underestimate how god-awful slow the big car makers are I think it’s exactly the opposite. People enamoured with Tesla and Musk tend to over -estimate how slow the old car makers are, because they’re so used to the “Silicon Valley story” that we will inevitably come in and take over everything. Look: it’s 2017. Everybody has read the Innovator’s Dilemma, everybody knows how fast e.g. Palm, Nokia, etc. went o…

> I really find it hard to believe they don't understand the TPS. Sure. Maybe. I don't know. American carmakers didn't get it for decades. Even when they thought they did, they performed Lean rituals without real understanding. This was despite Toyota trying vigorously to teach them.
History shows that knowledge transfer is really, really hard. Humans are just not very good at it :( (A similar story is told of the spread of the use of Feynman diagrams in physics - I’ve read that their spread was far slower than you’d expect given their utility: For whatever reason it wasn’t enough to be told that they were an incredibly useful tool by people you trusted - it was only when non users actually worke…

No, you did say that money solves production issues.
to clarify, what I meant by "issue" is production delays. There are underlying issues for sure, and those won't be solved just with money. But many side effects of delays are mitigated by throwing money at it. And spending money is usually an easy option, if you have a lot of it.
