The biggest takeaway from The E-Myth for me as a software engineer was the idea of making a job easy enough for the least qualified individual to do it. The example they use is how to train completely untalented 15-year-olds to make burgers at McDonalds. McDonalds doesn't need to hire chefs.

In software engineering, I've seen teams look for years for a candidate with X years of experience in technology Y. In many cases, you don't need an expert, you just need a smart person.

Build up a library of books/articles as well as sample code and exercises. Then hire smart people rather than experienced people. We had a git repo with exercises in functional programming and scala along with unit tests and day one involved checking it out and getting started.

Also, simple code is more accessible to the "least qualified individual". You may sacrifice performance, but you will be able to scale more effectively as an organization.
