ORSC ™ stands for Organization and Relationship Systems Coaching: an integrated coaching model based on Relationship Systems Intelligence ™. Beyond Emotional Intelligence (relationship with oneself) and Social Intelligence (relationship with others) is the realm of Relationship Systems Intelligence where one's focus shifts to the relationship with the group, team or system. This approach creates sustainable and resilient teams and families.

The framework has been developed by the international Center of Right Relationships, CRRGlobal.
