In 1998, in Working with Emotional Intelligence, I set out a framework of
emotional intelligence (EI) that reflects how an individual’s potential for mastering the
skills of Self-Awareness, Self-Management, Social Awareness, and Relationship
Management translates into on-the-job success. This model is based on EI competencies
that have been identified in internal research at hundreds of corporations and
organizations as distinguishing outstanding performers. Focusing on EI as a theory of
performance, this chapter presents a new version of that model, looks at the physiological
evidence underlying EI theory, and reviews a number of studies of the drivers of
workplace performance and the factors that distinguish the best individuals from the
average ones.
