Another valid analogy with large corporations is if central planning was the optimum strategy, then extreme micromanagement from the top would be the optimum business strategy. Surely it would take top level supercomputers and programmers to run an entire country, but any random MBA with an Excel spreadsheet could run a business more successfully than a business without TPS reports and content-free numbers. So observationally, micromanagement and management by metric number should be a sign of a highly profitable and successful company, yet its usually associated with dying companies or companies only kept alive by what boils down to corruption (monopolies, licensing, regulation, revolving door between .com and .gov, etc).

If there was a solid argument WRT scaling explaining why the result would be different at extreme scale vs business scale then the picture might be brighter for central planning.

There are also growth rate issues where your two examples are unfortunately companies experiencing an implosion of mindshare, people run from those companies as fast as they can, not run toward them. That is probably just an unfortunate coincidence but does look bad for central planning PR. There must be some "cool companies" that centrally plan and are successful? Or maybe there aren't?

I think that any large business is already too large for the top to micromanage things. No human has enough time and free computing power in their head to do that. That's why I believe central planning run by humans is unworkable - we're too slow to handle the complexity.

But then again, successful micromanagement happens - it's usually called "strong leadership", "CEO with vision", etc. Apple with Jobs and Amazon with Bezos come to mind as past examples (not sure how Amazon is doing now, but there was a lot of praise written for Jeff's micromanagement), and the most visible current one would be Tesla and SpaceX under Elon Musk.

Worth noting that Google seems to use Oracle Hyperion - you pretty much have to use tools like Hyperion for consolidated financial reporting once a company gets past a certain complexity level.
