This thoroughly updated third edition provides fresh insights into how and why organizations change, and why attempts to implement change commonly fall short. The authors explore the topic through contemporary perspectives such as hybrid work models, digital transformation, sustainability and diversity, equity and inclusion. Rather than promoting one single formula, the book presents 13 distinct philosophies on change, from rational planning and psychological approaches to systems, culture and institutional forces. Each philosophy is critically analysed, informed by practical examples, updated research and lessons from recent global disruptions such as the COVID-19 pandemic, digital transformation and climate challenges. Revisions across all chapters connect classic theories with cutting-edge developments, while an all-new chapter covers iterative, data-driven and digitally enabled change models. Adopting a pluralistic and comparative approach, the book demonstrates how lasting change requires flexibility, resilience and the capacity to integrate diverse ways of thinking. Scholars and students of management, business and organizational studies will benefit from this book's key takeaways. By unpacking the hidden assumptions behind popular models, it also equips leaders, managers and consultants with the understanding and agility necessary to succeed in today's unpredictable world.
