The sky is the limit. The IE background helps give you the skills to work in almost any field in any industry. What industry needs now is leaders with multidimensional skills. IE's have it. Industrial Engineers have the edge in most situations.
Leadership is more about working with and through people than having superior technical skills.
Industrial engineers learn about working with people from day one and their technical curriculum gives them enough learning that they can work in most any environment. As I visit companies, most company leaders have engineering backgrounds and the majority have served as industrial engineers. IE is not a guarantee, but it is a great start.
