This collection offers the full digital editions of two seminal books by global leadership expert John P. Kotter: his international bestseller, _Leading Change_, and _Accelerate_, his award-winning framework for enabling companies to compete and win in a world of constant turbulence and disruption. _Leading Change_—now considered the change bible for leaders and managers worldwide—reveals why change is so difficult and lays out an actionable, eight-step process for implementing successful transformations. Cited by business leaders and influential organizations worldwide as the book to read when starting any type of change initiative, _Accelerate_ (XLR8) vividly illustrates the five core principles underlying a new dual operating system, the eight accelerators that drive it, and how leaders must create a sense of urgency through role modeling. Perhaps most crucial, the book reveals how the best companies focus and align their people’s energy around what Kotter calls _the big opportunity_. If you’re a pioneer, a leader who knows that bold change is necessary to survive and thrive in an ever-changing world, these two books will set you on a path to accelerate into a better, more profitable future. Regarded by many as the authority on leadership and change, John P. Kotter is a _New York Times_ bestselling author, award-winning business and management thought leader, business entrepreneur, inspirational speaker, and Harvard Business School professor. His ideas, books, speeches, and the company he founded in 2008, Kotter International, have helped mobilize people around the world to better lead organizations, and their own lives, in an era of increasingly rapid change. Kotter has authored nineteen books to date—twelve of them bestsellers. His books have reached millions and have been printed in over 150 foreign language editions.
