Decision Making Intelligence is the second credibility builder and it is the ability to solve problems, resolve issues and come to conclusions that satisfy the various stakeholders and leave them feeling fully and clearly committed to the decision. It is about personal credibility and trusted judgment. In order to be credible, leaders must combine their Emotional Intelligence with a proven track record of superior decision making under a wide variety of circumstances and across a wide portfolio of business matters.
A leader must have the ability to understand and master the complex elements involved in the decision-making process, including the rational and interpersonal components, as well as the divergent and convergent phases. These abilities embody the essence of decision making within what is known as the field of Behavioural Economics. Our current understanding of this science comes from a growing pool of notable experts, such as Daniel Kahneman and Daniel Ariely, who have helped us better understand the mechanics of decision making and the phases we go through as we make business decisions in particular
Together, the powerful combination of Emotional Intelligence and Decision making Intelligence represent the fundamental building blocks upon which leaders develop their legitimacy. In other words, as Barbara Kellerman points out in her book Followership, leaders will not able to lead effectively unless their followers have determined them to be worthy. Legitimacy, defined in this way, is something granted to the leader by their followers. As such, it could be argued it actually puts the followers in control.
