Conflict resolution strategies is a range of processes aimed at alleviating or eliminating sources of conflict. The term "conflict resolution" is sometimes used interchangeably with the term dispute resolution or alternative dispute resolution. Processes of conflict resolution generally include negotiation, mediation and diplomacy. The processes of arbitration, litigation, and formal complaint processes such as ombudsman processes, are usually described with the term dispute resolution, although some refer to them as "conflict resolution." Processes of mediation and arbitration are often referred to as alternative dispute resolution.
