It takes a village to curate amazing lists from this rather busy group of leaders from all over the world. We would like to thank Kris Coratti, Chantal De Soto, Rimjhim Dey, Melanie Newman, Joellen Perry, and Jayne Rosefield for their help.

Within McKinsey Global Publishing, Eleni Kostopoulos led the effort to make this year’s list come alive, with collaboration and support from Mike Borruso, Nancy Cohn, Victor Cuevas, Torea Frey, Mary Halpin, Drew Holzfeind, Kathleen O'Leary, LaShon Malone, Philip Mathew, Janet Michaud, Kanika Punwani, Sarah Thuerk, Duane Tomaszewski, Petra Vincent, and Nathan Wilson.

And thank you to our contributors and their organizations for providing McKinsey Global Publishing with their photographs and permission to use them.
