I disagree that Tesla’s way differs from what Deming professed. In fact I believe Tesla is one of the best in the world at actually doing what Deming proposed, this this is a major reason why I’m invested. I say this as a quality engineer who has spent a fair bit of time studying Deming and the Toyota Production System.
Nothing in
Deming’s 14 principles indicates a focus solely on incremental improvement (“kaizen” in Toyota terminology) without any step-change radical improvements. And even so, Tesla’s rate of introducing incremental improvements to the production system is far beyond the rest of the industry, and it’s mostly driven by shop floor workers—a key tenet of Deming’s principles.
Sandy Munro was personally mentored by Dr. Deming while they both were at Ford, and he runs his company based on Deming’s teachings. The Munro and Associates website says, “Truly, the underlying Deming spirit and philosophy is evident in all the Munro products and services.” Sandy has called himself a “Deming disciple”. In fact, Sandy left Ford to start his own company
because Deming told him to. Considering that Sandy is enamored with Tesla’s way of doing business, I think it’s safe to say Deming would be too if he was still alive.
I published an essay on this topic from a couple years ago:

It is probably good that there is room for disagreement on both Deming himself and the revolution in Japanese industry fomented by his teachings;
As a matter of practice few adherents of Deming have actually practiced what Elon called First Principles, but there is no doubt that kaizen emphasizes what we would consider to be continuous improvement After all, everything Demings did was not focused on what manufacturing really meant, but rather on what was manufactured.
I admit to some bias, in large part driven by study of both Demings and places where be had the most influence. Since the qualifications we might have could be relevant, I did study Deming's work in some detail both at Columbia, before he arrived, and at NYU. Both of those were driven mostly by exposure to his work in Japan when I was working there, where he was nearly a minor deity.
Despite his massive accomplishments and the benefits of his thinking, over-simplified drastically by the 14 principles, nearly all his statistical base was devoted to production precision, as his famous Ford parts comparison with Japanese demonstrates. Indeed nothing explicitly says discontinuous innovation is precluded, but the very core of Demings ingredients is statistical process control, plus the crucial component of line worker input o the processes.
Those process do indeed yield very high quality. They do not explicitly consider the core capacity of materials innovation and applied physics to yield materials and process innovation.
Bluntly, Elon Musk invents. W. Edwards Demings made precise parts easier.
These are complementary, are the exceeding precise processes for cell production, Octovalve, plus rocket reuse...nearly all of Tesla and SpaceX can thrive only with precision that Demings could not have even conceived, nor could anyone back then.
Where divergence probably comes is perfectly analogous with investment management.
Demings and Graham were both seminal figures, firmly attached to the 20th century. Both are still useful, but neither adapt easily to rapid technological advance. In the world of generative AI and whatever comes next the tools themselves can build themselves, while the humans need to manage that process.
Thus, those hugely accomplished people can help us to better understand, but it is history, not today.
Without a single doubt I know that I do not have the ability to manage effectively today. That is probably why I cannot imagine voting for someone my age.
That is why I appreciate Tesla and SpaceX and have admired Elon Musk since just before PayPal. Hopefully I still can recognize such talents just as I hope that talent can survive endless attacks without breaking.
