By Mehrdad Baghai and James Quigley

You may not be providing the leadership your organization needs to function most cohesively. Baghai, the managing director of Alchemy Growth Partners, and Quigley, the CEO of Deloitte Touche Tohmatsu, believe many executives think too narrowly about how they make decisions and motivate employees. Leaders either exercise tight control or try for maximum collaboration. The authors use original research to define a spectrum between these extremes, taking into account what leaders want to accomplish and what employees expect. Portfolio Penguin, $40
