A power team is a group people of complementary professions. They work with the same clients, but do not take business away from each other. Successful business people have the ability to select and cultivate mutually beneficial relationships with high-quality people in strategically important business categories, and this ability is a core competency for maximum success in networking.
It provides clearer insight into your networking partner's business and life to help you understand them more as a person, as well as possibly uncovering money on the table with referral opportunities for the power team.
