Teams are becoming more popular in organizations as they allow better use of employee talents and are more flexible than individuals. A work team is defined as a group whose efforts are greater than the sum of individual inputs. Effective teams have adequate resources, clear leadership and structure, trust among members, and a performance evaluation system that rewards team efforts. Creating successful teams requires the right composition of members, roles, diversity, and size, as well as work design that gives autonomy and meaningful tasks. While teams often outperform individuals, they are not always the best approach and their success depends on factors like interdependent work and a common purpose.
