The realities of globalization, with increasing emphasis on emerging markets, present corporate leaders with enormous challenges in developing the leaders required to run global organizations. Too many multinational companies — particularly Japanese, Indian, German, and some American ones — still concentrate vital decisions in the hands of a small group of trusted leaders from their home country. They hire technical specialists, local experts, and country managers from emerging markets but rarely promote them to corporate positions. Instead, they groom future global leaders from the headquarters nation by sending them on overseas appointments.
