"In *Collaborate or Perish!*, William Bratton and Zachary Tumin lay out a field-tested playbook for collaborating across the boundaries of our new, networked world. Today, when everyone is connected, collaboration is the game changer. Agencies and firms, citizens and groups who can collaborate, Bratton and Tumin argue, will thrive in the networked world; those who can't are doomed to perish. Boston native William Bratton is known around the world for his ability to get citizens, governments, and industries working together to improve the safety of cities. At Harvard, Zachary Tumin has led executives from government and industry in sessions and classrooms for over a decade. Together, they draw on in-depth accounts from Fortune 100 companies, and the education, social work, and military sectors to discuss the keys to effective collaboration. "
