Working with a team a staff or any group for that matter is often a lot of fun and sometimes a real struggle.  Struggles are going to happen.  However I think they happen far too often.  A simple way to prevent and lessen the number of struggles on a team is to practice the art of communicating and clarifying.  Take time to clearly communicate.  Work hard on the front end of a relationship and then continue to clarify along the way.  Divisions are deadly and should be treated as the enemy that they are.
