Book excerpt: This innovative book analyses the evolving nature of leadership, exploring an ever-increasing range of theoretical concepts and applying these to practices within healthcare organisations. A wide range of theories are covered, from behavioural to attitudinal, socio-cognitive to contingency, and social exchange to team. By identifying the common underlying characteristics that are present in leadership styles and approaches, the author successfully crafts a useful model that is adaptable to different scenarios and contexts within the realms of healthcare management. Offering a series of detailed case studies from around the world, this book proposes three crucial concepts for leadership within the health sector: leadership credibility, professional credibility and organisational dynamics. Both scholars and practitioners will find the theoretical framework provided in this book insightful and applicable in real-life situations.
