The Right Fight, the new management guide from noted business strategists Saj-nicole Joni and Damon Beyer, turns management thinking on its head and shows why, in the fast-moving, hyper-competitive marketplaces of the 21st century, leaders need to both foster alignment and orchestrate thoughtful controversy in their organizations to get the best out of them. The authors’ groundbreaking research—including examples as diverse as Unilever, Microsoft, Coca-Cola, Dell, the Clinton Administration, and the Houston Independent School System—shows that happy workers can become bored or complacent and thus less productive than workers who are subjected to a little properly managed tension. Readers of Good to Great and Winning, as well as the Harvard Business Review and Strategy + Business, will find much to ponder in The Right Fight.
