We all work in teams of varying shapes and sizes, here are a few lessons to help teams work better:

Do:
Negotiate and agree explict (written if necessary) rules of engagement.
Continually give feedback.
Have respect for other points of view and address team issues immediately without procrastination.

Don't:
Treat team members as irrelevant.
Deny the importance of feedback.
Belittle contributions.
Break into subcommittees.
Cross talk.
Imagine you will all get along.

It is better also if you clearly define the Goals and Objectives of the team so that all members appreciate and understand their respective duties.
