What is an After Action Review? An After Action Review (AAR) is a tool designed to help teams assess their performance after completing a task, event, activity, or project. The primary purpose of an AAR is to facilitate a candid and constructive discussion among team members to uncover what was successfully executed, identify areas for improvement, and generate actionable insights for future endeavors. Unlike traditional performance evaluations, AARs focus on collective learning, fostering a culture of continuous improvement and adaptive learning within organizations. It is also a tool that can be used as a catalyst for cultural change.
