complaints. In this stage "...participants form opinions about the character and integrity of the other participants and feel compelled to voice these opinions if they find someone shirking responsibility or attempting to dominate. Sometimes participants question the actions or decision of the leader as the expedition grows harder..." Disagreements and personality clashes must be resolved before the team can progress out of this stage, and so some teams may never emerge from "storming" or re-enter that phase if new challenges or disputes arise. In Tuckman's 1965 paper, only 50% of the studies identified a stage of intragroup conflict, and some of the remaining studies jumped directly from stage 1 to stage 3. Some groups may avoid the phase altogether, but for those who do not, the duration, intensity and destructiveness of the "storms" can be varied. 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 together. Supervisors 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. Norming "Resolved disagreements and personality clashes result in greater intimacy, and a spirit of co-operation emerges." This happens when the team is aware of competition and they share a common goal. In this stage, all team members take 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. Performing "With group norms and roles established, group members focus on achieving common goals, often reaching an unexpectedly high level of success." By this time, they are
