An After Action Review (AAR) is a structured process used to analyze what happened during a project or event. It focuses on identifying successes and areas for improvement by gathering feedback from participants. The goal is to learn from experiences to enhance future performance. Typically conducted soon after an event, an AAR involves discussing key questions: What was supposed to happen? What actually happened? Why did it happen? This reflective practice is commonly used in various fields, including the military, business, and emergency response, to foster continuous improvement and effective teamwork.
