When two people work together difference of opinion is bound to happen. So, just imagine a team of 10 or more people. The chances of misunderstanding and clash of views is inevitable here. Here the leader has to play a very important role. He has to bring about consensus within the team and make the team understand what the objective of the team is. He should be able to convince the team that the decision being taken is in the larger interest of the team and one that will help them achieve their targets. This would lead to a positive reaction within the team even if their opinions and decisions were not considered. If they know why their opinion was not considered, they will not react in a negative manner.
I would like to end with a nice quote on leadership:
"Leadership is the art of getting someone else to do something you want done because he wants to do it. "
