This document summarizes the key findings of a 2009 study on the tribalization of business conducted by Deloitte, Beeline Labs and the Society for New Communications Research. The study surveyed over 400 companies and found that most see online communities as important for increasing word-of-mouth, loyalty and awareness. However, many communities are not well integrated with business goals and processes. Successful companies treat communities as networks and focus on customer needs over company priorities. To fully leverage communities, companies need new management strategies and integrated processes.
