In jack's work group, members are developing close interpersonal relationships that have led to an emerging sense of unity and harmony within the team. This is an example of the activities that occur during the norming stage of group development.
Finding out why and how small groups evolve over time is the main objective of most group development studies. A group's cohesiveness, the nature and frequency of its activities, the quality of the work it produces, and the presence of group conflict. To describe how certain groups change through time, a number of theoretical models have been proposed. Sometimes, like in the case of therapeutic groups, the kind of group being studied had an impact on the suggested model of group development.
One of the most commonly referenced models of group growth was created by Bruce Tuckman in the middle of the 1960s after reviewing roughly fifty studies on group development. According to Tuckman's model of group growth, a group will go through four linear stages in its unitary sequence of decision-making: forming, storming, norming, and performing. When a fresh batch of trials were examined in 1977, a fifth stage—adjourning—was added.
