English: A complaint system (also known as a conflict management system, internal conflict management system, integrated conflict management system dispute system) is a set of procedures used in organizations to address complaints and resolve disputes.

In contemporary language, these discussions centered on the "interests" of all who would consider themselves stake-holders in a given conflict—and on systems change—as well as resolving grievances.
