This new core textbook addresses the key issues of how organisations build and develop leadership capability and examines how this ability is a key element in delivering organisational success. Focusing on the behavioural aspects of leadership, it looks at how both individuals and organisations can develop leadership talent, and how leaders can influence and shape the strategic direction of an organisation as a whole. Drawing on case studies from a variety of contexts, and punctuated with questions and activities to encourage reflective learning, the text takes a decision-making approach and looks at how senior leaders come to make and implement decisions that maximise organizational performance. This book is the ideal companion for undergraduate and postgraduate leadership students, as well as practitioners, researchers and scholars in the field.
