A proficiency in finding common ground with others, and building rapport is known as social skills. Leaders with well-developed social skills are able to build vast personal networks, and are usually experts in managing relationships.
Leaders with social skills are characterized by their effectiveness in championing change through the management of relationships. They communicate and interact effectively with those individuals around them. These leaders are adept at leveraging the networks they have fostered to cobble together effective teams. Finally, because of the close relationships they have built with others, they can be a very persuasive member of the workforce.
Social skills are one of the five dimensions of emotional intelligence, as described by Daniel Goleman. The other four dimensions of emotional intelligence include: motivation, self awareness, empathy, and self regulation.
