Teams in an organization are more than cooperative working groups. Advantages of group work, as opposed to individual work, include producing a better end result, providing satisfaction for the individual and the organization, and assisting the organization through coordination and work allocation.

Four key questions need to be answered to decide the pros and cons of team work. Team work has its limitations. Building a team involves management in 10 key activities. The key properties and performance characteristics of a highly effective team suggest an ideal that groups should work to achieve and a set of criteria against which to measure the effectiveness of existing groups.
