At this year's CMO Summit, we explored what skills chief marketers need to look for as they build best-in-class teams, ways to develop their marketing talent and how to build their own careers. In this brief video, Kathy Button Bell, vice president and CMO of Emerson; Esther Lee, executive vice president and CMO of MetLife; and Deborah Wahl, CMO of McDonald's USA, talk about the capabilities marketing teams need and why there is no such thing as a perfect skill-set today.
