business organization.
There are some interesting ideas out there, but not many trying things. Most companies are “sole proprietorships”, and frankly not much need for organizing the workers when it is only oneself.
Holacracy looks promising, but I don’t think it is stress tested. I like the idea of being certified in various skills and being able to work on those topics (maybe this isn’t holacracy).
Large type books are a thing. (And a plug for the free libraries perhaps in your area. Which may also have e-books.)
