When Avon needed a makeover two years ago, Jung practically reinvented the company. She united its disconnected international operations into what she called a global "company for women." For the first time in its 115-year history, she placed in stores products that were competitive with other big brands. She enlisted as an Avon lady, listening to customers and developing incentive and recruiting programs that revitalized the sales force. And as China opens wider to trade, Jung, 42, has a big advantage: though born in Toronto, she learned Mandarin from her parents.
