2) "Proof of Leadership" identifies six key dimensions of leadership: the leader's vision, beliefs, change model, ability to influence, values, and behaviors.
3) The model is then applied to analyze several iconic, business, and political leaders like Martin Luther King Jr., Abraham Lincoln, Steve Jobs, Alan Mulally, Hillary Clinton, and Donald Trump. Applying the six dimensions provides a concise way to understand the essence of each leader's approach.
