So am I guaranteed to fail at developing a platform for selling used cars if I have never worked as a used car salesman and have no idea how they work? Of course not, I am supposed to acquire the necessary understanding by talking to users and subject matter experts. I think the same holds for managers, you can understand and manage a software development process without having been a developer. Does experience help, could former used car salesman develop the platform better, could former developers manage the team better? Sure, but only if they are also good in their current role, if they are good developers or a good manager. And being good in your current role comes first, having experience in the field you are writing software for or that you are managing is an added bonus.
