Groups are collections of individuals who share information and make decisions to help each member perform their own tasks, while teams have members who work interdependently to achieve shared goals greater than any individual effort. Effective teams exhibit synergy, with coordinated efforts exceeding the sum of parts. Organizations prefer teams because they outperform individuals, use talents better, and facilitate involvement. To create effective teams, organizations should select candidates with team skills, provide training in areas like problem-solving and communication, and reward cooperative rather than competitive efforts.
