About the Book: How Change Really Works provides a science-based framework for making organisational transformation successful. Boston Consulting Group experts Julia Dhar, Kristy R. Ellmer, and Philip Jameson reveal why many change initiatives fail and how leaders can overcome common pitfalls by understanding human behaviour. Drawing on research, real-world case studies, and executive experiences, the book presents seven principles for effective change and a practical five-phase guide for implementation. It challenges the idea that people resist change, showing instead that successful transformation depends on trust, agency, engagement, and thoughtful leadership.
