Tuckman's stages of group development
The Forming – Storming – Norming – Performing model of group development was first proposed by Bruce Tuckman in 1965, who maintained that these phases are all necessary and inevitable in order for the team to grow, to face up to challenges, to tackle problems, to find solutions, to plan work, and to deliver results. This model has become the basis for subsequent models.
The team meets and learns about the opportunities and challenges, and then agrees on goals and begins to tackle the tasks. Team members tend to behave quite independently. They may be motivated but are usually relatively uninformed of the issues and objectives of the team. Team members are usually on their best behavior but very focused on themselves. Mature team members begin to model appropriate behavior even at this early phase.
The forming stage of any team is important because the members of the team get to know one another, exchange some personal information, and make new friends. This is also a good opportunity to see how each member of the team works as an individual and how they respond to. so forming plays great role in in group forming and to understand each other behavior.
Tolerance of each team member and their differences should be emphasized; without tolerance and patience the team will fail. This phase can become destructive to the team and will lower motivation if allowed to get out of control. Some teams will never develop past this stage; however, disagreements within the team can make members stronger, more versatile, and able to work more effectively as a team. Supervisors of the team during this phase may be more accessible, but tend to remain directive in their guidance of decision-making and professional behaviour. The team members will therefore resolve their differences and members will be able to participate with one another more comfortably. The ideal is that they will not feel that they are being judged, and will therefore share their opinions and views. Normally tension, struggle and sometimes arguments occur. This stage can also be upsetting.
In this stage, all team members take the responsibility and have the ambition to work for the success of the team's goals. They start tolerating the whims and fancies of the other team members. They accept others as they are and make an effort to move on. The danger here is that members may be so focused on preventing conflict that they are reluctant to share controversial ideas.
By this time, they are motivated and knowledgeable. The team members are now competent, autonomous and able to handle the decision-making process without supervision. Dissent is expected and allowed as long as it is channeled through means acceptable to the team.
Supervisors of the team during this phase are almost always participating. The team will make most of the necessary decisions. Even the most high-performing teams will revert to earlier stages in certain circumstances. Many long-standing teams go through these cycles many times as they react to changing circumstances. For example, a change in leadership may cause the team to revert to storming as the new people challenge the existing norms and dynamics of the team.
Adjourning, Transforming and Mourning
In 1977, Tuckman, jointly with Mary Ann Jensen, added a fifth stage to the 4 stages: adjourning, that involves completing the task and breaking up the team (in some texts referred to as Mourning).
Norming and re-norming
Timothy Biggs suggested that an additional stage be added of Norming after Forming and renaming the traditional Norming stage Re-Norming. This addition is designed to reflect that there is a period after Forming where the performance of a team gradually improves and the interference of a leader content with that level of performance will prevent a team progressing through the Storming stage to true performance. This puts the emphasis back on the team and leader as the Storming stage must be actively engaged in order to succeed – too many 'diplomats' or 'peacemakers' especially in a leadership role may prevent the team from reaching their full potential.
John Fairhurst TPR Model
Alasdair A. K. White together with his colleague, John Fairhurst, examined Tuckman's development sequence when developing the White-Fairhurst TPR Model. They simplify the sequence and group the Forming-Storming-Norming stages together as the Transforming phase, which they equate with the initial performance level. This is then followed by a Performing phase that leads to a new performance level which they call the Reforming phase. Their work was developed further by White in his essay "From Comfort Zone to Performance Management" in which he demonstrates the linkage between Tuckman's work with that of Colin Carnall's "coping cycle" and the Comfort Zone Theory.
