An After Action Report (AAR) is a structured review process used to analyze what happened during a specific event or operation. It focuses on identifying successes, challenges, and lessons learned to improve future performance. AARs are commonly used in military settings, but they are also valuable in business, emergency response, and project management. The report typically includes a summary of the event, objectives, outcomes, and recommendations for improvement. By documenting these insights, organizations can enhance their strategies and decision-making processes. AARs promote accountability and continuous learning, ensuring that teams can build on their experiences for better results in the future.
