The main characteristic of a high-performing team is goal-oriented. Set clear goals every three months on what it is they need to achieve. After three months, you can set new goals or correct the team if they have strayed from the original goal.
Keep the team aligned by having weekly meetings. It allows the team to collaborate and work together and keep everyone aligned on your goal.
Create a feedback mechanism where everyone can share their thoughts and feelings without any judgment. This strengthens the bond of the team.
Managing burnout is a huge part of a high-performing team. Rest should be encouraged to avoid mistakes. Take breaks when necessary and after achieving goals and milestones.
