There is a difference between being a committee member and a team member.
Take a look at Webster definitions of Committee and Team:
Committee- (noun) a person to whom a charge or trust is committedTeam- (noun) two or more draft animals harnessed to the same vehicle or implement; also: these with their harness and attached vehicle
If you are a member of a team, you are there to partner with others. You have a common goal. You lay aside special interests and trust your coaches (leaders) are looking at the big picture.
Leaders we need to ensure we are cultivating proper environments so that the teams or committees we are can flourish. Committees need strong facilitators to help drive decisions but little connection between members. Teams need guidance, direction and strong connections between it’s members.
