Tony Chatman, author of The Force Multiplier wrote the book as a way to address a gap in leadership in a more practical, and less theoretical, way that would be applicable to everyone — from first-time leaders to executives. Chatman argues that if first-time leaders have a solid foundation about what it means to be a leader, they can avoid a number of pitfalls when they become executives. He also defines a ‘force multiplier’ as someone who brings out the best in others simply because of their presence. This, Chatman says, is “what makes a leader indispensable.”
