A team is built by selecting people from different backgrounds. A team leader or organizer develops a team by considering the role that fits the members' personality, specialty, and interest level. If an organization develops a team taking into account Tuckman's team development theory and Belbin's team roles, team members who behave like strangers come to work together to achieve a common goal become successful in no time. The first phase of team development is forming. At this stage, team members are anxious due to unclear responsibilities and goals. Since they come from different fields, they do not develop mutual trust. A team leader plays a crucial role in this phase. The second phase is that of the storm in which each individual tries to free their ideas and abilities. This is the most important phase for the growth of the team, although stressful. Therefore, a team fails to function due to disagreements and conflicts that arise among members (Staggers, Garcia, & Nagelhout, 2008). Slotegraaf and Atuahene-Gima (2011) stated that a successful team goes through a difficult phase to make an efficient decision. After considering different ideas, a team heads to define a common goal in a mutual decision. This phase is a normalization phase. Individuals in this stage take on their responsibilities and work towards the success of the team. In the fourth stage, the team progresses to the performance state where team members feel comfortable working effectively and making significant progress without any assistance (Staggers et al., 2008). Upgrading is the final phase that occurs after the project is completed. Good team members often experience difficulties and a sense of loss due to the good working relationship (Staggers et al., 2008). In today's competition... middle of paper... theory works effectively if a team has a mix of task orientation, people orientation and critical thinker. As far as Tuckman's theory is concerned, each group goes through phases. Therefore, a team must act correctly in its role at different stages of work to achieve an effective result.
