Another aspect of an organization’s relationship with its community is the way it collaborates with other organizations. No single organization can effect lasting change in a community. Organizations must collaborate—by planning together, sharing resources, and using complementary strategies—to amplify their work. Organizations that do not collaborate risk working at the margins and limiting their impact. A collaborative network of organizations— working locally, statewide, regionally or nationally—increases its chances to affect public policy, influence public opinion, and make lasting change.
