For analogies sake, if tesla has 1 thousand engineers in a centralized format. Could gains be made by decentralizing and opening select portions of their development process to millions of engineers, tinkerers and hackers around the world.
And the new Tesla will look like this probably:
I wonder how much people will push this decentralization madness, I can't wait to hear when the army will be decentralized.
Costs and efficiency.
History has thought us that simple solutions are the best, people look for the best choice at the money value, if you want custom stuff you go to companies that build custom cars and pay the extra $, for mass producers this would be impossible while keeping a low price.
Having a product come in three hundred versions will put an enormous strain on the logistical chain to supply 1000 different optional packages for each car, making some of them a money pit, that's why all car manufacturers offer just a few options for the same element, not five hundred colors and not 10 types of seats or 20 headlights designs for the same model.
And those decisions on what to offer need to be taken in a centralized mode or there will be chaos, manufacturing a car is not the same as creating firefox add-ons.
I love that simpsons reference.
Fate being what it is, I can give you at least 2 real examples of decentralized engineering significantly improving tesla's development process and products.
There's an engineering channel on youtube called munro live that tore down different tesla cars offering commentary, analysis and advice for improvements tesla could make on their vehicles.
https://www.youtube.com/watch?v=YQSQYQ44QcoThey removed the worst videos they had posted 1-2 years ago that showed the worst design choices tesla made in their cars. Long story short there was a long list of suggestions they made which were very embarrassing to Elon Musk and tesla. Instead of burying the criticism or resorting to lawsuits, tesla used the feedback to make better cars.
One of their suggestions for improvement was that tesla utilize a 48 volt based system, rather than the traditional 12 volt. This would allow tesla to use wires that were half as thick. Using only 50% of the copper, which could significantly decrease production costs. Another of their suggestions that improved tesla vehicles was a recommendation that tesla not use 3-5 different metal types to build their rear fenders.
Anyways if anyone wants a clear cut example of the advantages a decentralized approach to engineering can offer. Watch some of the videos posted in the munro live channel on youtube. They tear down vehicles and comment on the production and development process utilized to build cars/trucks. Its very surprising how much potential for improvement there is, in the production and manufacturing process with independent & decentralized review.
