After Action Reports (AARs) provide a retrospective analysis of critical actions to evaluate performance, document effectiveness and efficiency, and analyze procedures and policies to recommend improvements. AARs benefit policymakers, administrators, responders, and communities by providing a broad understanding of events and enhancing future planning. They should be used anytime an organization undertakes a project, event, or incident, both large and small. AARs have a simple structure including an overview, goals/objectives, performance analysis, lessons learned, and recommendations. Their value is in preventing future issues and improving responses.
