Inspired by the work of Peter Drucker and Jim Collins, Justin Menkes set out to isolate the qualities that make for the best leaders. Drawing on his background in psychology and bolstering it with interviews with accomplished CEOs such as John Hammergren of McKesson, Thomas Ebeling of Novartis, Rick Lenny of Hershey Foods, and others, Menkes paints the portrait of the ideal executive. His work reveals an executive IQ- the cognitive skills necessary in order to excel in senior management positions, from recognizing the needs of shareholders to challenging flawed assumptions. With extensive research, Menkes identifies these key qualities that every executive needs to succeed.
