With only 21 percent of women in senior management in the U.S., is America at risk of a "brain drain?" The answer is probably "Yes," as corporate executives shop the world for talent to manage their fast-growing businesses.
There's a business case to be made for the results women bring to the table -- but to really see more women in leadership positions, we need CEOs to understand that greater diversity at the most senior levels of business will help them gain a competitive advantage.
The bottom line is this: Stretching yourself too thin will not allow you to put your best foot forward and splitting your time between too many boards can prove to be very challenging (even for the most experienced board members).
Old habits die hard. For decades board members were chosen among the friends and colleagues of the CEO and others on the board. Since boards were comprised almost exclusively by men and in particular by other CEOs it is not surprising to find so few women.
We are witnessing a shift in the nature of leadership. The command and control structures we have inherited from traditional leadership are making way for styles characterised more by empathy, partnership and collaboration than by ego.
