Nano Tools for Leaders® introduces after-action reviews (AARs) as a practical leadership method for continuous performance improvement and adaptive learning. Developed by the United States Army in the 1970s, AARs help teams learn from both successes and failures through four guiding questions about intent, execution, differences, and next adaptations or repeatable wins. The process builds transparency, selflessness, and candor, strengthens teams using relevant facts, and enables organizational-wide sharing of lessons learned.

NANO TOOLS FOR LEADERS® AFTER-ACTION REVIEWS: A SIMPLE YET POWERFULTOOL Nano Tools for Leaders® are fast, effective leadership tools that you can learn and start using in less than 15 minutes—with the potential to significantly impact your success as a leader and the engagement and productivity of the people you lead. THE GOAL Create a culture of continuous performance improvement and adaptive learning by systematically reviewing team successes and failures. NANO TOOL Called “one of the most successful organizational learning methods yet devised,” the after-action review (AAR) was developed by the United States Army in the 1970s to help its soldiers learn from both their mistakes and achievements. Since then, many companies have used the AAR for performance assessment. And yet, as Peter Senge notes, efforts to bring the practice into corporate culture most often fail because “again and again, people reduce the living practice of AARs to a sterile technique.” The process itself is an active discussion centered around four key questions: 1. What did we intend to accomplish (what was our strategy)? 2. What did we do (how did we execute relative to our strategy)? 3. Why did it happen that way (why was there a difference between strategy and execution)? 4. What will we do to adapt our strategy or refine our execution for a better outcome OR how do we repeat our success? The AAR is not merely an opportunity to focus on team performance, but also serves as a catalyst for cultural change. To set the stage for effective AARs, leaders must first create a climate of transparency, selflessness, and candor where team members can challenge current ways of thinking and performing. Everyone—leaders included—must openly share where their own performance may have contributed to a team failure, and acknowledge the people and practices that helped create the team’s success. Used regularly to assess successful and unsuccessful events, AARs will strengthen teams and improve performance, and can become ingrained into the DNA of the organization. When key learnings from AARs are shared, the experiences of one team can benefit the entire organization. ACTION STEPS Going through the motions of an AAR is relatively easy—putting AARs into the DNA of your organization is the challenge. The following steps will help to make AARs a “living practice” that can transform team and organizational performance. © University of Pennsylvania, The Wharton School 1. Schedule after-action reviews consistently to learn from both successes and failures.“Post-mortems” have a negative connotation that discourages participation and enthusiasm. AARs should be held during or immediately after successful and non-successful events, using the positive positioning of improving your own performance and not that of someone else. 2. Gather relevant facts and figures related to the team’s performance. If project deadlines have been missed, product standards are being ignored, or client feedback is disregarded in the team’s execution, these facts set the foundation for an AAR that is grounded in relevant data. 3. Make participation mandatory and involve all team members in the discussion—even customers, partners, and suppliers can be included. Each participant will likely have a different perspective on the event, and this serves as a key input into the AAR. Everyone’s voice is important, so you must be able to receive criticism from a few levels down. Open-ended questions that are related to specific standards or expectations will encourage involvement. 4. Have a three-pronged focus: performance of team members, the leader, and the team as a whole. Keeping the attention on facts and outcomes, what are the strengths and weaknesses of each? This focus keeps the discussion centered on what the team can control (as opposed to what is happening at headquarters or on another team) . 5. Follow the “rules of engagement.”To encourage honest participat
