Group Behaviour - Stages of Group Development

Stages of Group Development

Group development focuses on the somewhat unique way groups are formed and the manner in which they may change over time. There are a variety of development theories and some suggest that groups develop through a series of phases culminating in effective performance. The most common of these models is Tuckman’s (1965) Stage Model. It breaks group development into the following five stages:

  • Forming: As the group convenes, conflict is usually low to non-existent as everyone tries to determine their individual role and the personalities of fellow team members. This stage is often marked by agreeable neutrality while the group takes form and begins to navigate the unknown.
  • Storming: Storming occurs after the group overcomes the sense of uncertainty and begins to actively explore roles and boundaries. Chaos, pronounced efforts to influence others, and instances of conflict and/or enthusiasm are common.
  • Norming: Norming in groups indicate that norms and role ownership are emerging. Generally this means that conflict and chaos is decreasing or has ended.
  • Performing: Originally noted as the final stage, performing occurs when the team completes their primary task(s).
  • Adjourning: Tuckman (1977) refined the model to include a fifth stage to address how the group begins to disengage and move on to new tasks potentially beyond the team.

While Tuckman’s (1965) model is useful in describing developmental processes, there are instances when groups do not strictly adhere to the exact sequence. Additionally, the storming stage may decrease but not fully dissipate and continue across other stages.

Famous quotes containing the words stages of, stages, group and/or development:

    The playing adult steps sideward into another reality; the playing child advances forward to new stages of mastery....Child’s play is the infantile form of the human ability to deal with experience by creating model situations and to master reality by experiment and planning.
    Erik H. Erikson (20th century)

    The four stages of man are infancy, childhood, adolescence and obsolescence.
    Art Linkletter (20th century)

    Belonging to a group can provide the child with a variety of resources that an individual friendship often cannot—a sense of collective participation, experience with organizational roles, and group support in the enterprise of growing up. Groups also pose for the child some of the most acute problems of social life—of inclusion and exclusion, conformity and independence.
    Zick Rubin (20th century)

    The experience of a sense of guilt for wrong-doing is necessary for the development of self-control. The guilt feelings will later serve as a warning signal which the child can produce himself when an impulse to repeat the naughty act comes over him. When the child can produce his on warning signals, independent of the actual presence of the adult, he is on the way to developing a conscience.
    Selma H. Fraiberg (20th century)
