There is a very good exercise that helps build trust and understanding among team members. During a team meeting, ask each person to answer four questions:
1. In 30 seconds, describe what you are working on.
2. Where did you grow up?
3. How many kids were in your family?
4. What was the most difficult challenge that you had to overcome in childhood?
At the end of this exercise, you will be surprised about things you didn't know about people you may have been working with for a long time. And it will help you to trust them and work with them better.
