Forming: is the initial stage of team development. This is the getting-acquainted stage in which team members first meet each other, form initial impressions, and try to get a sense of what it will be like to be part of the team. Some of the first team norms will be established during this stage as team members begin to find out what behaviors will and won't be accepted by the team. During this stage, team leaders should allow time for team members to get to know each other, set early ground rules, and begin to set up a preliminary team structure.
Storming: Conflicts and disagreements often characterize the second stage of team development, storming. As team members begin working together, different personalities and work styles may clash.Team members become more assertive at this stage and more willing to state opinions. This is also the stage when team members jockey for position and try to establish a favorable role for themselves on the team.In addition, team members are likely to disagree about what the group should do and how it should do it. Team performance is still relatively low, given that team cohesion is weak and team members are still reluctant to support each other. Since teams that get stuck in the storming stage are almost always ineffective, it is important for team leaders to focus the team on team goals and on improving team performance. Team members need to be particularly patient and tolerant with each other in this stage.
Norming: team members begin to settle into their roles as team members. Positive team norms will have developed by this stage, and teammates should know what to expect from each other. Petty differences should have been resolved, friendships will have developed, and group cohesion will be relatively strong. At this point, team members will have accepted team goals, be operating as a unit, and, as indicated by the increase in performance, be working together effectively. This stage can be very short.
Performing: performance improves because the team has finally matured into an effective, fully functioning team. At this point, members should be fully committed to the team and think of themselves as members of a team and not just employees. Team members often become intensely loyal to one another at this stage and feel mutual accountability for team successes and failures. Trivial disagreements, which can take time and energy away from the work of the team, should be rare. At this stage, teams get a lot of work done, and it is fun to be a team member.
