Management is an interesting concept. My personal view on it is that I don't want to work with people who need to be managed.
So don't call it management, call it leadership instead. If you're on a team of peers and you're the natural leader who helps motivate everyone and makes the idea a reality, you are essentially the manager... the PHB, but you are doing it artfully.
In lots of businesses, one is not fortunate enough to be able to hire self-motivated employees, and so management is akin to being the old lady on the school yard with a whistle.
But more broadly, management is the science of motivating people... and anyone who is a "founder" and can't do the project alone must fill those shoes to some extent.
Maybe what I'm trying to say is that there is no such thing as management, only mismanagement.
