Among Lewin's studies T-Group and Laboratory Training have a great importance. His studies reveal that
despite individual differences, members of a group may act harmoniously towards a common goal. He points out
the significance of common fate and occupational interdependence while determining group dynamics. If
individuals anticipate their own fate is depended on the group's, which they are members of, they will willingly
share the group's responsibilities. According to occupational interdependence dynamic, if the group members
sense they need each others to reach the group's common goal, they easily understand and support each others
(Smith, 2001).
