" To tear down silos, leaders must go beyond behaviors and address the contextual issues at the heart of departmental separation and politics. The purpose of this book is to present a simple, powerful tool for addressing those issues and reducing the pain that silos cause. And that pain should not be underestimated. Silos—and the turf wars they enable—devastate organizations. They waste resources, kill productivity, and jeopardize the achievement of goals. But beyond all that, they exact a considerable human toll too. They cause frustration, stress, and disillusionment by forcing employees to fight bloody, unwinnable battles with people who should be their teammates. There is perhaps no greater cause of professional anxiety and exasperation—not to mention turnover—than employees having to fight with people in their own organization. Understandably and inevitably, this bleeds over into their personal lives, affecting family and friends in profound ways. "
