Conciliation is an additional step proposed in the dispute resolution process.
The conciliator meets with the parties separately at a so-called pre-caucus. The purpose is to help each party release their pent up concerns enough to enable them to gain a broader perspective on the dispute.
The parties then meet together at a joint session, where they discuss directly with each other instead of through a mediator.
The conciliator is there to help the parties take responsibility for managing their own conflict, rather than to judge between the merits of the position of one party or the other.
