We all have at our fingertips the work of many researchers, scholars and specialists who develop excellent theories and write wonderful books about leadership. My contribution, then, will focus on my experience and spring from what I have lived and live in my daily activities. I have occupied managerial or executive positions in many different organizations. I have been an executive with IBM in my native Argentina and with Telecom, where I was the CEO of the then third largest company in my country. From there I moved to the multilateral world and became COO of the World Food Programme in Rome, to later be appointed as Under-Secretary-General in New York in support of the United Nations Peacekeeping Operations worldwide. I then finished my career in the United Nations as Chief of Staff (called “Chef de Cabinet” in the UN), a position that I left to become Minister of Foreign Affairs and Worship of Argentina. Today, I am Dean of the School of Global and Public Affairs at IE University in Madrid. I am also one of the founders of GWL Voices for Change and Inclusion, an organization whose members are 54 women who have occupied important positions in the national and international arenas and whose purpose is to advance multilateralism and gender equality in the world.
