Group Structure
A group’s structure is the internal framework that defines members’ relations to one another over time. The most important elements of group structure are roles, norms, values, communication patterns, and status differentials.
A role can be defined as a tendency to behave, contribute and interrelate with others in a particular way. Roles may be assigned formally, but more often are defined through the process of role differentiation. Role differentiation is the degree to which different members of a group have specialized functions. Functional (task) roles are generally defined in relation to the tasks the team is expected to perform. Other types of roles are the socio-emotional role which helps maintain the social fabric of the group, the individual role and the leader role.
Group norms are the informal rules that groups adopt to regulate members' behaviour. Norms refer to what should be done and represent value judgments about appropriate behaviour in social situations. Although they are infrequently written down or even discussed, norms have powerful influence on group behaviour.
Group values are goals or ideas that serve as guiding principles for the group. Like norms, values may be communicated either explicitly or on an ad hoc basis. Values can serve as a rallying point for the team. However, some values (such as conformity) can also be dysfunction and lead to poor decisions by the team.
Communication patterns describe the flow of information within the group and they are typically described as either centralized or decentralized. With a centralized pattern, communications tend to flow from one source to all group members. Centralized communications allow consistent, standardization information but they may restrict the free flow of information. Decentralized communications allow information to be shared directly between members of the group. When decentralized, communications tend to flow more freely, but the delivery of information may not be as fast or accurate as with centralized communications. Another potential downside of decentralized communications is the sheer volume of information that can be generated, particularly with electronic media.
Status differentials are the relative differences in status among group members. Status can be determined by a variety of factors, including expertise, occupation, age, gender or ethnic origin. Status differentials may affect the relative amount of pay among group members and they may also affect the group's tolerance to violation of group norms (i.e. people with higher status are given more freedom to violate group norms).

Famous quotes containing the words group and/or structure:
“He hung out of the window a long while looking up and down the street. The world’s second metropolis. In the brick houses and the dingy lamplight and the voices of a group of boys kidding and quarreling on the steps of a house opposite, in the regular firm tread of a policeman, he felt a marching like soldiers, like a sidewheeler going up the Hudson under the Palisades, like an election parade, through long streets towards something tall white full of colonnades and stately. Metropolis.”
—John Dos Passos (1896–1970)
“Vashtar: So it’s finished. A structure to house one man and the greatest treasure of all time.
Senta: And a structure that will last for all time.
Vashtar: Only history will tell that.
Senta: Sire, will he not be remembered?
Vashtar: Yes, he’ll be remembered. The pyramid’ll keep his memory alive. In that he built better than he knew.”
—William Faulkner (1897–1962)
