Book excerpt: An important part of every manager's job is changing people's behavior: to improve someone's performance, get them to better manage relationships with colleagues, or to stop them doing something. Yet, despite the fact that changing people's behavior is such an important skill for managers, too many are unsure how to actually go about it. This book reveals the simple, but powerful techniques for changing behavior that experts from a range of disciplines have been using for years, making them available to all managers in a single and comprehensive toolkit for change that managers can use to drive and improve the performance of their staff. Based on research conducted for this book, it introduces practical techniques drawn from the fields of psychology, psychotherapy, and behavioral economics, and show how they can be applied to address some of the most common, every-day challenges that managers face. #changingpeople
