“If you ask people what is characteristic of the best groups they have ever been members of, the same traits keep being mentioned: small, informal, egalitarian, inspired by shared goals, the knowledge that what they do is recognized and valued. They report that the group does its work in a spirit of energized sharing, with much constructive self-examination. … Groups fail in organizations mainly because they are in organizations. They reflect the surrounding cultures—rigid, formal, and highly political in many cases.”
