Influential leaders from each of the sectors public, private, and nonprofit in every region of the world have issued a call for leadership within and across sector boundaries, boundaries that have inhibited economic and social wealth creation in times of great need. The United Nations has worked to identify critical areas of focus and investment: extreme poverty and hunger; primary education; gender equality and female empowerment; child mortality; maternal health; eradication of HIV/AIDs, malaria, and other diseases; environmental sustainability; and global partnerships for development. Like many large organizations public, private, and not-for-profit Wharton has developed a set of seven leadership competencies to which it devotes significant resources and programs. The seven competencies that constitute the Wharton dimensions of leadership are influence, emotional intelligence, teamwork, communication, decision making, diplomacy, and organizational awareness. This chapter provides case studies that illustrate successful succession planning through leadership development; Ashoka: innovators for the public; Eisenhower Fellowships (EF).
