ADR stands for Alternative Dispute Resolution, which are methods used to settle disputes without going to court. It's like solving problems without involving a judge. ADR includes techniques like mediation, where a neutral person helps parties find a compromise, and arbitration, where an impartial person makes a decision. These processes are often quicker, less formal, and more cost-effective than going to court, making them popular for resolving conflicts in various settings, such as businesses, communities, and even legal matters.
