This book is the follow up to the 1999 bestseller First, Break All the Rules, which identified the 12 most important elements that all great managers share. In 12, the authors once again draw from The Gallup Organization’s database—which now includes 10 million employee and manager interviews—to give real-life examples of how managers from around the world epitomize each of the 12 Elements. In addition to the Gallup data, the authors use the latest insights from brain-imaging studies, genetics, psychology, behavioral economics and other scientific disciplines to reveal what drives good managers.
