You have to convince management that they don't need management. Good lucky with that.
Also the managers where they dont understand importance of code quality and measure everything by how much closer to the end product they are.
The managers, who dont understand that sometimes the code just rots and developers have strong sense of intuition when this happens. Do listen to them.
The managers who dont understand that complexity of a code increases exponentially with every feature. And telling developers, "oh you just need to add this simple script to the program" can be as dangerous as drunken driving. Ok not as that dangerous, but in case you are making software for autopilots and all.
