The initial stage of team development is when the team is formed. This is when the team learns about each other, agrees on specific goals and assigns tasks to each member. At the beginning, the team leader may be a group member. The next stage is when more details are discussed and an approach to tasks is developed.
Clear goals are made, roles are defined (even deeper here) and the team leader should discuss acceptable team behavior and team communication skills here. During the next stage, the team should be using tools and methods in order to show mutual trust, motivation and open communication in the workplace. The team will continue to grow in terms of communication, cohesiveness and feedback overtime. The team leader is responsible for ensuring the team is running smoothly.
