Do Different Leaders in Different Functions have Different Skills?

In my last post, I posed the question whether a leader needs technical expertise in the area they lead. If the answer is yes, it implies that different leaders have different problems to solve. IT leaders have IT problems. Customer Service leaders have customer problems. And so on.

However, Peter Drucker makes a point that all managers have the same problems:

"…management everywhere faces the same problems. Is has to organize work for
productivity; it has to lead the worker towards productivity and

So you have to ask yourself; re managers on your organization leading people towards productivity and achievement? And does it matter whether they are finance managers or operations managers?
