After Action Review
After Action Review (AAR) is a structured process for reflecting on and analyzing completed projects, tasks, or events to identify what went well, what didn't, and how to improve future performance. It involves gathering participants to discuss successes, failures, and lessons learned in a collaborative, non-blaming environment. Originally developed by the U.S. Army, it is widely used in business, software development, and other fields to foster continuous improvement and team learning.
Developers should use AARs after major project milestones, sprints, or deployments to systematically capture insights and prevent recurring issues. It helps teams improve processes, enhance collaboration, and build a culture of transparency and accountability. In agile or DevOps contexts, AARs complement retrospectives by providing a focused, action-oriented framework for post-mortem analysis.
