It answers why the analyst think Tesla's way of doing things is an issue:
> the Japanese, try to limit automation because it "is expensive and is statistically inversely correlated to quality." Their approach is to get the process right first, then bring in the robots — the opposite of Musk's.
And, a hypothetical but expansive example on why Tesla's automation strategy might not achieve the desired cost savings.
Of course, they use Japanese workers, which have a completely different work ethic than American workers.
I say that having worked in an American assembly line (not automotive though). I haven't worked in Japan myself, but the attention to detail of Japanese workers in even the most menial of jobs is amazing.
The Japanese manufacture most of their American market cars in America, using American labor.
Take your biases somewhere else, this isn't the place for them.
German cars are substantially better in quality, and finding high mileage German or Japanese cars is easy, finding French or Italian high mileage cars is much more rare.
Isn't that the point of GP's comment? They're not saying french cars are well assembled, they're saying japanese cars are even worse:
> the assembly quality of Japanese cars lags far behind even French cars, and that's saying something
(emphasis mine)
French cars haven't rusted in decades. But that doesn't mean their assembly quality is better than the Japanese.
And I'm not convinced that Japanese cars are so bad in the rust department either.
The last batch of really badly rusting cars - ironically - were Mercedeses from the early 00's. Mercedes totally missed the boat on the water based paint front and got it dramatically wrong leading to a ton of re-work and expensive warranty issues.
> the assembly quality of Japanese cars(Toyotas especially) lags far behind even French cars [let alone German]
All our Citroen cars NEVER showed any sign of rust. Our BX was 15 years old, when the hydro-pneumatic system fell apart. Citroen are known for excellent attention to corrosion protection on essential parts. I know a BX nearby from that era (must now be ~30 years old) that seems to be flawless.
Our VW Golf IV we currently own has had almost no exposure to the winter in his 17 years, apart from the last 2-3 years. He began rusting badly last winter, this will unfortunately end very soon.
High mileage German cars are available (I can only speak for middle Europe), because they have extraordinary value degradation (in terms of slow degradation), i.e. people still want them, because they are supposedly longer lasting, and supposedly better quality.
Maintenance statistics speaks otherwise. And god repairs on VWs are expensive. Just a new key fob is easily 5x as expensive as on a Citroen!
Edit: This blog-post [1] would indicate that my information is no longer valid. But then there is this post as well [2], which could be due to individual maintenance costs being higher for "luxury brands". Needs more research.

Citroen CX and DS as well as 2CV were notorious for being rust buckets, the ones that are left have had tons of money poured into them. CX and injected DS were notorious for catching fire. Another major issue with the CX was euphemistically labeled 'gearbox separation' (I've actually had that happen to me on one of the two CX's that I owned, a 2400, super nice car but with the gearbox landing on the street it didn't get very far). The second one suffered a collapsed piston. All in all not the best score :), and that's before we get to rust issues. They were beautiful cars though, and super comfortable.
The more modern ones did not rust so much because Citroen got their rust problem under control somewhere in the mid 80's early 90's, hydraulics were a lot better too. The C5/C6 were probably the best cars Citroen ever made before they really became boring, and the DS is still a head turner after 60 years since it was first introduced, and it will always be my favorite car, even if I no longer drive them. On the plus side, my current car has the same suspension.
Parts for German cars are indeed ridiculously expensive but then again, they fail less frequently.
High mileage vehicles are the best way to check how reliable a car is, if it works out well the drivetrain and engine will outlast the chassis. I've had VW Golfs (older diesels) with 250K plus on them and a whole slew of Mercedeses, never a problem that caused the car to be stranded. I've never owned a BMW so I can't say anything about those but my French cars have been a long list of all kinds of interesting problems. I didn't mind, it taught me a lot about working on cars (and doing an engine rebuild on a DS is something special), but they never were very reliable. Oh, and I forgot to include one Citroen in my list, Xantia diesel which was fairly low mileage (180K) when it spectacularly blew up the head somewhere on the way back from Switzerland. That wasn't a fun trip at all.
Yeah, I remember my dad telling me those were known to rust almost immediately, and they apparently (to his perception, based on the cars we owned) not only got their act together, but excelled at it, somewhere end of the 80ies/beginning of the 90ies.
And that is true, the BX has considerable plastic parts (although only the front hood and the front mudguards, which is awesome if you ever bump something, nothing happens!), the non-visible chassis is still metal and very rust-safe.
On a side note: Our Renault 21 Nevada from the early 90ies was a different beast... I think almost everything on it had to be replaced randomly, and although it made it to 270k or more (I think), my dad was happy to leave it behind and he only kept it because it was a company car.
Renault never really got their quality control in order, they are still hit-and-miss today. If you're lucky you will have a fantastic car if you don't it will nickle-and-dime you to death. I've had a couple of Espaces, I absolutely love the form factor but the reliability and general quality are horrible.
For example, the Mehari used a lot of plastic parts (ABS) and is from the late 60ies.
It didn't prevent rust completely however. For example, the Mehari was as prone as the 2CV to have a chassis breakup.
My father actually got one with a broken chassis (in fairness, more due to the fact it has been driven in very rough roads around South Europe and Asia Minor in the 70ies) and spent a summer disassembling it completly to replace the chassis (he still has a beautiful photo with all the parts laying around).
One thing to keep in mind is that the Mehari, as the 2CV, was designed to be a very simple and cheap car from the 60ies (the 2CV design even traces back to the 30ies). This actually somewhat wonderful as it's possible for a single person to service these cars alone with a few basic tools if he knows a thing or two.
also, local manufacturer where I live are famous for messing up hiring non qualified workers. Panda had a recall because seats weren't correctly screwed in, for example. most of the time when you dig the faults are in the manual part of the lines. And the Alfa I drive has only one misaligned component, and it's the manually placed windshield - the alignment mark are off more than an inch!
that's not to say that the problem is in the workers themselves, because their training and their efficiency is part of how the company configure the plant, but it's not just the work ethic of individual workers, more like the work culture of the whole company
You are absolutely right. The work ethic of Japanese workers is awesome.
I am an engineer and I am damn sure that the Japanese use humans to perfect a process and then replace them with a robot, with the same human manning the robot. Japanese workers and management always work together to perfect a process to such an extent that it becomes very easy to replicate it with a machine.
Its very inspiring to see the Japanese work.
It also means basically the workers behave more and more like a robot. I don't think it produces happy humans.
But given Japan has such a high suicide rate and depression I would not bet on them for having found it yet.
But let's be honest, I haven't worked, let alone lived in Japan, so this is just uneducated gut feeling.
https://en.wikipedia.org/wiki/Salaryman
though things are changing nowadays.
I have a relative who for 40 years has done the exact same job -- he drives a large dump truck from a stone pile in a rock quarry up to the crusher, dumps his load, and repeats, endlessly.
He's had many opportunities to transfer to other positions, but he enjoys his "meaningless" work.
He's retiring soon, which is good since the company has been testing an automated truck.
Moreover, even with the process automated, often, a finishing touch is given by the operator. And, often, Japanese manufacturing facilities, depend on human skill and ingenuity to extract maximum quality from the process, even if the process is heavily automated.
In addition to all the above, one unique aspect of the Japanese workforce and management, and I have seen this first hand, is that even the lowest level worker can freely give his inputs regarding a process and then the upper level workers, engineers and managers actually listen and discuss the inputs.
In the plants that I have been to, engineering, design and workers are all located on the factory shop floor and are expected to work together in unison.
One seems way more satisfying than the other, not matter how good one can become at turning the screw.
Even this simple product has numerous subtle steps in its production.
Yet on operator may very well do one to three different move, 10000 times a day. It's very tedious. Perfecting that is certainly satisfying, but it's hard for me to grasp how it can counteract the crushing experience of it all.

Tesla is solving a very narrow problem of a single model of the vehicle with limited parts inventory and somewhat reduced complexity (peculiar to EVs in general), offering very little customization (customers can choose the color and the interior, but that’s about it).
https://www.google.com/amp/s/www.wsj.com/amp/articles/behind...
The stock ticker is TSLA, all you have to do is load up. No need for chest thumping.
Disclaimer: I work for a Tesla competitor.
I'm not so sure about electric cars, but I would judge a rocket to be less complex than an ICE car. Rockets just have much more spectacular failure modes and are more expensive due to size.
Testing is also very different. For a car, you can build a batch and test it extensively under all conditions, fixing errors as they come up. If you develop an assistance system, you can test this extensively before releasing it. Rockets are so expensive that SpaceX had only a few trials for their landing system. You need to make sure that both hardware and software work perfectly without ever testing them in production.

I don’t really think there is any way in which the adjective “terrible” would be an appropriate use of the word here. Also note the low numbers involved here, the different contexts and the plain arbitrariness of such comparisons. One failure more or less can make a world of difference here, despite maybe not being the most reliable indicator.
94% is about the long term ballpark figure for successful orbital launches but it is true that some newer rocket families may have ever so slightly higher reliabilities.
What about Soyuz? IIRC, they haven't lost a manned mission since 1971.
Neither has SpaceX :)
Soyuz is somewhat more complicated since it's an entire family of rockets:
The Soyuz-FG (2001-today, currently does all manned flights) has a 63/63 success record.
The Soyuz-U2 (1982-1995) also has a 72/72 success record.
The Soyuz-U (1973-2017, also manned flight) has a 765/786 (97%) success rate, with no failure in their manned flights.
The Soyuz-2 (2004-today) has a 68/75 (91%) success rate.
And over time their failure rate has been dropping steadily, since 1/1/2017 they've launched about half of all F9s and all have worked perfectly. It's gotten to the point where the press will crow 'failure' if they don't manage to land the first stage on the barge, which is apples-to-oranges with the rest of the industry, who are - rightly - getting seriously worried.
So yeah, this could apply to Tesla cars. Or rubber toys, which are also manufactured in a highly automated environment.
Tesla's inability to quickly ramp up Model 3 production is pretty much one of those "fact" things at this point. The same goes for every model they've brought out, it's taken a long time to get decent production rates on any of them. So this isn't so much predicting problems he's going to have, but explaining the causes of all the problems they've already had and are having right now.
Can't help but think that if learning to get really good at robotics is a strategic goal, then that's something which might pay off later.
when his 100% robotic and autonomous ships mine an asteroids and bring back huge payloads we'll still probably see articles like this.
This kind of comment is a disservice to all the engineers who actually figured it out. Elon Musk is certainly a visionary and a financier, but is not a 1000x engineer/mathematician who did all the work himself
Go listen to Tom Mueller for example. Musk himself says at SpaceX 80% of the time he is working on engineering not traditional 'CEO' things..
Go listen to Tom Mueller on the design choices made for the Merlin example.
But of course nobody does everything himself, but for some reason I read this sort of comment made about Musk in every single thread but not with most other people.
Bear in mind that the first time one of his staff proposed verticals landing rocket stages, he laughed.
> Warburton, who spent his career before Wall Street at the International Motor Vehicle Program — a partly academic, partly commercial organization based at MIT — wrote that "automation in final assembly doesn't work."
It doesn’t even matter since it’s not public money. Which makes me wonder about the analyst’s intent: Tell people not to invest? Do people not know Tesla is super-risky? but if they succeed to obliterate this anchored rule that automation doesn’t work in the final assembly, isn’t that a superwin that stakeholders dream of?
Friends who invested in Tesla didn’t “invest” so much as “donated” money for what they think is a good cause. And perhaps because it’s fun to hear the NASA chief say “I had asked my engineers and they told me it wasn’t possible”.
I’d pay for that kind of fun.
"They have concluded that improvements to conventional engines will be key over the next 10 to 15 years and HEVs will become viable on a large scale by 2020. They believe near-term mass market adoption of electric vehicles is unlikely given the tough financial comparison with ever improving combustion engine vehicles. While premium-priced plug-ins may become viable earlier, by definition they will be niche products."
https://seekingalpha.com/article/310159-bernstein-and-ricard...
sounds like one of those sad stories where the engineers fell in love with the stack and forgot about the product.
Sounds like Steve Jobs... in 1986.
Chassis, drivetrains and minor parts-bin components are developed group-wide by VAG. Putting them together in the desired pattern and adding premium components and materials is what makes an Audi.
All Audi A, Q and TT models are examples of this. They are built in shared plants with other VAG models which use the same platform. Even the R8 has a shared platform.
In contrast AFAIK Tesla does everything bespoke without the advantages of volume and standardisation.

Disclaimer up front: I work for a Tesla competitor.
Tesla is making several very interesting bets on the Model 3.
Bet 1: Model 3 mix - Tesla is betting that the ratio of expensive, high-content Model 3s to cheap, low-content Model 3s will be sufficient to make enough money to offset investments and pay back loans.
It will not be sufficient to make a small profit on each Model 3 sold given the debt load that Tesla has accrued, so they will want to sell a good ratio of expensive Model 3s.
If it takes to long to produce the cheaper Model 3s, Tesla will lose some potential customers. Many investors are looking at that "top line" right now - the number of customers and potential customers. If the top line moves too much, investors may get spooked.
Bet 2: Vertical Integration - Most automakers rely on a web of parts suppliers, who are under enormous pressure to reduce costs, but Tesla produces most of its components in-house. The contract with an external parts suppliers ensures that the supplier is responsible for any re-work or replacement of defective parts. This allows the automaker to concentrate on internal production issues.
Tesla's bet is that internal production of parts will lead to better and cheaper components. This has not worked for any other automaker.
Traditional OEMs shoot for a mix of components where the internally produced components are part of the company's core competence: Body Shells, Engines, Transmissions - and externally produced components may be generic - switches, latches, seats, frames, tires, wheels, etc.
If Tesla spends too much capital on component manufacturing, they will be inefficient and investors pressure them.
Additionally and probably more importantly, if Tesla is not able to spend the time and attention to iterate on cost and quality of these parts, it will also lose this bet.
Personal opinion: I think Tesla has learned the wrong lesson from previous dealings with suppliers. For instance, the original Roadster was designed with a two speed transmission. A supplier claimed they could make it, but it never really worked. Tesla learned the lesson that suppliers are stupid and suck at making new things - I think they should have learned that lesson that it is really really hard to make new things.
Bet 3: Automation - But first a detour - There are 3 main areas of auto assembly, and most manufacturers have already fully or almost fully automated 2 of them: Body Shop (welding and assembly of the body shell) and Paint Shop. The 3rd area is General Assembly.
General Assembly is the bloody, thorny, devilish poster child for multiple single points of failure. A high feature vehicle may have on the order of 1000 assembly stations (aka footprints) in General Assembly. The Model 3 is designed with much lower complexity in mind, and may only have 100 footprints.
If and when any of those 100 footprints has an equipment failure or parts issue, ALL 100 stop running in a short amount of time. Human assembly workers are rather resilient and can figure out a multitude of small issues on each and every operation. This may allow for a hypothetical variation of 5% in non-critical parts.
Automated assembly may only allow for a 1% variation.
Additionally, automated assembly only runs well when EVERYTHING is designed for automation. That is not impossible, but it is expensive and time consuming.
---
Most importantly, these three bets are linked:
If not enough base models are sold, the cost of design and equipment spending will be excessive on a per vehicle basis.
If internally produced parts are too far out of spec, you have strong negative impacts on automation.
If automation fails, you cannot produce enough vehicles at a low enough price to satisfy your low-end customers.
But, if Tesla wins all three bets, they win big time.
Regarding these bets, I'm not sure on which side I'm on. You want them pushing the limits, Tesla itself was a long shot as a company. It's also meant to not just produce electric cars, but to also drive change in other car manufacturers so that they advance towards electric cars and maybe also self driving cars.
However, if they keep piling on the bets, at some point they will go under and I think we still need the company.
Your post makes me believe that they are pushing things a bit too much, like a startup. Yet they are at a later stage in the life of a business, considering their scale. It's like a bank using MongoDB 0.5 in production several years ago.
But automobiles are not their only revenue source. They also sell
* residential and commercial solar systems and roofing material
* residential and commercial battery packs
* batteries
* as of recently, electricity through Supercharger Network
Tesla's biggest Capital Expenditures have been in service of the Model 3, that's why we're talking about it.
The cash infusions go further - when SolarCity needed some expansion capital and sold bonds backed by residential customer solar leases, SpaceX (which at the time was flush with cash from a VC round) materialized as a major buyer http://blog.solarcity.com/spacex-invests-90-million-in-solar...
I visited the Mazda plant in Hiroshima, and enjoyed watching robots working with people. (the window install unit is the one which I saw with a high degree of integration) It felt like the mix in a stable, well understood plant was pretty good. Welding by robots doesn't mix well with people side by side, but some welds were still being done by hand. I doubt they do this because they have choices: it would only make economic sense to use people to do some welds, if robots did them worse, given you have the robots there already with welding guns.
I think this kind of flexibility probably epitomises what car manufacturers have to learn from Taylorism onwards: it takes a long time to understand what mix of auto and manual construction works best. If Tesla is trying to short circuit this, thats high-risk: cutting time out of a time consuming learning exercise risks mis-learning, or not learning.
It's working well for SpaceX who are doing just that while the incumbents in the rocket industry are not and the prices reflect how well it can work.
> Traditional OEMs shoot for a mix of components where the internally produced components are part of the company's core competence: Body Shells, Engines, Transmissions - and externally produced components may be generic - switches, latches, seats, frames, tires, wheels, etc.
Ummm, which automaker makes it's own transmissions anymore? Quite a few don't even make their own engines either (Dodge with Cummins engines, Jeep with VM engines, etc. etc.)
Toyota simply used their people more effectively.
Of managers and MBAs, not of line workers.
Automation isn't necessarily just about replacing people. It can also be used to make the people you have a lot more productive.
For instance: http://www.autonews.com/article/20080914/OEM02/309149956/a-s...
"GM number crunchers had pegged the investments in EDS, Hughes and Fanuc at $40 million in the long run. Instead, they cost $66 billion. In the end, GM's plants were no more efficient, and sales plummeted as money was spent on conglomeration rather than developing products Americans wanted to buy."
Other car makers take no risk in the short term by not investing to automate more final assembly. But 2 times more is not like 10 times more. It is very probable that Tesla will get to have lower production cost & better capacity than other car makers in just a few more years.
Yeah I know they may need more cash very soon and are way under their targeted rate, but Musk still has lot of money in the bank I think?
I always think of Tesla of a company with a more long-term vision than other car makers. I think analysts sometimes just want a lower the price so they can get more of it.
These analysts, what are they analysts in?
"Let's say there are 10 hours of labour in final assembly (the part of the production line where parts, interiors and the powertrain are installed in a painted bodyshell). In a regular plant, final assembly typically has less than 5% of tasks automated. If Tesla attempts to automate 50% of these tasks, it could cut out 5 or so hours of labour. This might save $150 per car (assuming wage rates, all in, of $30 per worker, per hour).
"But while all that exotic capital might allow Tesla to remove 5 workers, it will then need to hire a skilled engineer to manage, programme and maintain robots for $100 an hour (our estimate of a robotic engineers' hourly rate).
"So the net labour saving may be only $50 per unit. Yet putting the automation into the plant seems to involve an apparent capital cost that's $4,000 higher per unit of capacity than for a normal plant. If the product is built for 7 years, that's over US$550 of additional depreciation per unit built. It's hard to see an economic case even if somehow the Fremont Model 3 line can be made to work. So why exactly has Tesla taken this route? It's unclear."
http://www.businessinsider.com/tesla-robots-are-killing-it-2...
Even if you have sufficient data to train an algorithm, you still need AI experts who understand the domain (another big obstacle) and the cost of these AI experts creating and maintaining the algorithm needs to be less than the cost of the workers who's jobs you want to automate.
If it were as simple as being able to perfectly replicate a skilled human and do everything 10x faster, then this should really be simple. The fact that automation is so problematic suggests to me that there are a lot more variables and problems.
People will go crazy, say that he lost everything, he is stupid, etc... But he will not give a f%#k just to return with double power and hit like no other.
Another aspect is potentially repairs itself. If every part can be added by a machine, they could later be removed and swapped out as part of the maintenance cycle too
Programming an automated line to build a car (or any other product) in a different way is a tremendous amount of work, since all of the motions have to be exactly right. Usually customization weighs heavily in the favor of humans, who can adapt much more easily to parts that are different.
Also, an automated production line isn’t going to be any use for repairing cars, all it can do is bolt them together.
These aren’t some kind of AI robots. They are mechatronics that are programmed to follow very specific toolpaths. Reprogramming them by even a few millimeters is a monumental task, and to test them, you have to try to build a car ...
They already have advanced computer vision, for a new facility surely they'd be building this in at least partially
Was the whole innovation economy all snake oil? How many of the “Unicorns” will be left in the middle of the next decade?
I can easily see building out and proving the final assembly automation being related to Elon Musk's Mars colonization ambitions.
"What is the inspiration behind Tesla's automation? Tesla has bought German robots and a German automation company (Grohmann). But the German OEMs – traditionally the most enthusiastic proponents of automation – have actually been rowing back on it in recent years. The best producers – still the Japanese - try to limit automation. It is expensive and is statistically inversely correlated to quality. One tenet of lean production is “stabilise the process, and only then automate”. If you automate first, you get automated errors. We believe Tesla may be learning this to its cost."

Couple that with a couple of Tesla bigshots walking when they heard Elons plans for fixing the Model 3 production schedule and you can see why things are not looking all that rosy right now.
10x the PR and the you have successfully projected the illusion of capable of doing the impossible in front of the naive public...Worked well for Elon till now..
And I think Theranos did much more than make people say what they are doing is not really feasible...
