Patterns Over Time

In the 1960s, a five-phase model of how group urbanized over time become accepted. In this model, the first period is形成,a time of uncertainty and examination into group purpose, behavior, and arrangement; then comes anattack阶段，关于领导，角色和任务的大量冲突。从这个阶段，小组进入形成阶段，当亲密关系扩大并群体凝聚力增加时。第四阶段是表演：现在，该小组可以从事手头的业务并开始产生产出。最后阶段，adjourning,occurs when the instant task is finish and before the next scheme is conventional, or in "wrapping up" a temporary group.

While this model is intuitively appealing, there is little evidence to show it is what really done in groups. Its main usefulness is in reminding managers that conflict is a necessary part of the development of groups: A group with no disagreement is unlikely to create high-superiority work.
