What is After Action Review (AAR)?

A four-step process developed by the US Army and now used by businesses and other organizations. An AAR is a structured review or debriefs process for analyzing what happened, why it happened, and how it can be done better by the participants and those responsible for the project or event. AAR’s should be carried out with an open spirit and no intent to blame. The American Army used the phrase “leave your rank at the door” to optimize learning in this process. Some groups document the review results; others prefer to emphasize the no-blame culture by having no written record. AAR is a form of group reflection.
