Step1
When mediating a situation you must first open a line of communication between the parties involved in the dispute. You might separate them by seating them at opposite ends of a table, across the room from each other or even in opposite rooms.
Step2
By separating the parties in some manner you can then open up a dialog, encouraging them to speak one at a time, and exchanging their own thoughts, feelings, and defining the issue from their own personal point of view.
Step3
When acting as a mediator it is important that you stress to the combatants that your role is not to take either side but to help them work the issue out in a calm logical manner that will be beneficial and positive to all sides.
Step4
Help the antagonists see that an issue can have more than one resolution and point of view.
Step5
You also need to help the opposing sides distinguish wants from the true underlying needs.
Step6
Although your position as a mediator is not to provide the solution you can propose ideas or suggestions if the combatants cannot think of any and then let them respond.
Step7
Since most conflicts and confrontations are emotionally charged to the point the antagonists are unable to see clearly any logical end to the conflict it is critical that you, as the mediator, help them look for a logical solution.
Step8
Give all parties an opportunity to speak, give them equal time, and take each of them seriously so as not to antagonize them further.
Step9
You must make it clear to the combatants in a clear and practical manner what could happen to them if they cannot resolve their issues.
Step10
Finally, if the situation continues to escalate to the point that some kind of violent interaction might occur, you may have to consider calling in some kind of security personnel or law enforcement.
Step11
Never leave yourself, others, or either antagonist open to violent behavior.
