Teams consist of employees from diverse backgrounds working together for a specific period of time on projects. According to Stephen Robbins, a work team is a collection of people whose combined efforts result in performance greater than the sum of individual contributions. Teams generate synergy by coordinating individual member efforts. There are various types of teams including problem-solving teams, self-managed teams, and cross-functional teams composed of employees from different departments collaborating to complete tasks. Effective teams require the right environment, skills, clear roles, and rewards to maximize performance.
