Earlier quoted context omitted.
Whilst I have sympathy with your cynicism 1) that's not true of _good_ managers and 2) processes are the raison d'etre of HR, which is hardly a male-majority profession.
I would argue that HR is much more about dealing with people, and managers are responsible for providing systems for the people to work effectively in. Especially if you are upper management, you aren't going to be working with people most of the time, you are going to be finding ways to make them work more effectively in a systemic way.
Mind you, quite a few people think an HR officer is the right person to go to with a problem. This is a _very_ bad idea. HR's job is to protect the firm, not the employees (sometimes this involves pushing out someone senior, but that's unicorn-level rare). If you want someone to represent your interests at work, it's time to unionize. :)
