It is impossible to assume that every project will go smoothly if everyone works together as a team. The Project Manager must build and lead the team. They also have to create the right structures and ensure that each member of the team has the right opportunities, as well as clearly defined roles and responsibilities.
To create an effective team, all members of the team must work together in order to achieve collective goals. This does not happen automatically. The project manager must put in his efforts using his skillset and experience. When the team is assembled, it is not a team. It is just individuals who are assigned to work together. As the project progresses, the members of the team get to know one another, get a sense of what their expectations are, get a sense about the tasks assigned, and get a sense of how to coordinate the work.
Team development is the process of learning how to work together effectively. Every team goes through different stages in team formation and development while working on a project. Dr. Bruce Tuckman states that every team involved in a project goes through different stages of development before it becomes productive, effective, and high-performing. These stages of team formation are, Forming-Storming-Norming-Performing-Adjourning.

Every project manager must conduct a team building exercise that is appropriate to their team’s size and characteristics to ensure the project’s success.

Some team-building activities could include:
Participating in the planning of the project with the creation of the WBS
Presentations by the team to assess and improve their processes, interactions and relationships
Collaborative problem-solving
Milestone parties
Team members can celebrate their birthdays, attend weddings and picnics.
Arrange indoor activities such as team board games or inventing a game.

A well-designed project team is essential for any project. This team can be extremely effective under the direction of a project manager who is proactive, collaborative and collaborative. These five essential elements are necessary to build a successful project team.
Establish a strong leadership
Clearly Defined Roles and Responsibilities
Open and Clear Communication
Conflict Management
Recognition and Rewards
1. Establish a strong leadership
Any Project Manager can have a positive impact on the people who report to him/her directly or indirectly. This includes being a great motivator and a diplomat liaison, an adaptive leader, and having passion that will help him/her build a high-performing group.
Effective leadership is essential to build a team. A leader who is effective encourages his team to work together as well as to do their individual tasks.
Any project manager must establish trust and loyalty with his/her team members by building relationships that are based on trust and not fear. He/She should be involved in the team’s day-to-day activities. He/she must be proactive in addressing any problems that may arise.
The leadership of a project manager does not mean to impose authority on others. Leadership is the ability to build trust and communicate honestly in a transparent manner. Project managers must be accessible to all members of the team in case of any problems, whether they are present with the team or not.
These are some things that project managers can use to help them establish effective leadership.
Every decision made by the Project Manager must remain transparent and should be communicated to all members of the team.
As per the team charter, the Project Manager should assign tasks and responsibilities in the most efficient way possible for all team members. The Project Manager should not assign too many tasks to team members, while leaving others with more work.
The project manager should communicate clear goals to all members of the team. He/she should also help them understand it by communicating clearly without any misunderstandings.
The Project Manager must be honest with all team members and encourage them to follow his or her lead.

2. Clearly Defined Roles and Responsibilities
Every member of a team should be aware of their roles and responsibilities. Each member of the team will know their roles and responsibilities and can contribute to the success of the project by being clear about what they are doing.
