According to Brian Uzzi, a management professor at Northwestern University, networks come with three major advantages: private information, diverse skills, and power. By developing a strong network, people can gain invaluable access to knowledge, expertise, and influence. Extensive research demonstrates that people with rich networks achieve higher performance ratings, get promoted faster, and earn more money. And because networks are based on interactions and relationships, they serve as a powerful prism for understanding the impact of reciprocity styles on success.
