Can any one give me a brief idea about Conflict Management?
What specifically are you looking for?
Briefly, conflict management is about managing conflict. Not sure what else I can say without knowing more about what you are asking.
Are you talking about the conflict that arise on requirements and managing those conflicts?
I think you will find that Wikipedia has an extensive discussion on the topic. http://en.wikipedia.org/wiki/Conflict_management
They even move into the realm of conflict resolution, which might be more along the lines of what you are looking for.
I hope this helps,
