1.   Fully accepted system of bringing the various conflicting sides to one place.

2.   System of increasing communication among them so that the conflicting groups can compromise.

3.   Developing an adequate system of compensation in order to force the dangers of external and internal stress so that the actors of sub-units of conflict succeed in establishing necessary harmony.

4.   The system of limiting the force used by the actors or sub-units of conflict on the whole organisation.
