Niccolo Machiavelli famously wrote: "There is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success than to take the lead in the introduction of a new order of things". Constructing a new order of things, which Edmondson and Reynolds call "building the future", is the focus of this book. It explores how to bring complex new systems into being, particularly systems that transform human experience and make the world more livable and sustainable. Intense collaboration across professions and industries is vital to come up with new ideas and innovative solutions. This requires practicing new forms of leadership that enable complex, team-based, whole-system innovation. To reveal how pioneers build the future, Edmondson and Reynolds study a startup's long and innovative journey in the smart-city industry, which uses digital, information and communication technologies to enhance the quality and performance of urban services, They follow the leaders in this company, Living PlanIT, through cycles of hope, exhaustion, disillusionment, pragmatism, and renewal in creating the city of the future.
