Whether in the for-profit, not-for-profit, or government sector, organizations today face tough new challenges posed by changing global and domestic environments using diverse workforces. Leaders have to practice different styles appropriate to more complex and dynamic situations than ever before. They need to inspire trust, gain credibility, and implement innovations through others while remaining flexible and adaptable. The contributors to this comprehensive volume seek to define exactly what leadership is or should be, and how to effectively develop it. Guided by a unique framework that looks at leadership across different sectors and functions, they examine what they view as the major leadership challenges in highly visible for-profit, not-for-profit, and government organizations throughout the world. Their insights will prove equally useful as a general survey of leadership problems and solutions for executive policy makers, as well as a text for advanced undergraduate and graduate students.
