Teams have become the building blocks of organizations (Lawler, Mohrman and Ledford, 1992). As organizations grow in size and become structurally more complex, groups of people are needed who work together in coordinated ways to achieve objectives that contribute to the overall aims, effectiveness and competitiveness of the organization. Team working provides the flexibility needed to respond effectively, appropriately and more quickly than competitors to the constantly changing demands in the organization’s environment, and provides a mechanism for bringing together the range of expertise, skills and knowledge required to complete complex work tasks.
