In 1984 McGrath defined a group as an entity comprising of two or more people. In his perspective, the group was deemed to be small to maintain the integrity and dynamics of a group structure while accounting for the independent opinions of the group members. But in his classification, a group structure normally included families, small social and friendship groups or work crews. In the contest, Turner in 1987 defined a group structure as a unit which has a psychological meaning for the members. In his process of thought, when a member joins a group he drives norms and beliefs from the group itself which as a result affect the member’s attitude and behavior. Turner distinguished an individual’s affiliation to the group as more like a reference than a mere membership. Drawing from these perspectives, eventually, a group or a team, as a whole, is defined as an affiliation of two or more people who interact directly or indirectly in order to achieve a common goal (Earley amp. Gibson, 2002).
Given the complexity of today’s work requirements, interdependence and correlation among employees are an unavoidable aspect of a work environment. In today’s global structure, people work interdependently, interacting with each other to maintain working and social norms at a workplace. Groups and teams do not mean the same thing even though both these terms are used interchangeably these days. A group is defined as one or two people who have gathered together and are gaining satisfaction by the collective influences with no special attention to the common goal, whereas team is a structure where people are organized together.
