A manager of anything, including technology, should have an understanding of what they manage. Not having that understanding is the fundamental problem. Any kind of "guides" to help such ill equipped managers is only a band aid that doesn't fix the actual underlying problem.
Technical managers may cost more an be harder to find. That might just be the cost of not screwing up things in major ways. Including potentially business destroying ways.
An additional clue: Not just the immediate managers of the worker bees, but going up the chain of management there should be people who understand the technology.
Nobody would accept the idea of a manager that didn't understand the business they are in. If technology is part of your business, and you don't understand technology, then you don't understand the business you are in and shouldn't be a manager.
