How we pick the Most Powerful Women
The Most Powerful Women in Business list is compiled by FORTUNE editors, who consider four criteria: the size and importance of the woman's business in the global economy, the health and direction of the business, the arc of the woman's career (resume and runway ahead), and social and cultural influence.
