I was recently invited to take part in a discussion about why it matters there are so few women on corporate boards of directors and in senior executive roles. At first, I was surprised we are still debating such a fundamental question. But as I pondered the theme, I realized there is still at least one critical difference of opinion about this topic.

I’ve interviewed many senior business men and women about their efforts to boost the number of women on boards, and they all agree improving diversity in senior roles is important because it improves their bottom-line profitability. The universal argument is: “It’s good for business.”
