An after-action review (AAR) is a structured, reflective process used by teams to analyze what happened, why it happened, and how future actions can be improved. Originally developed by the U.S. military, the AAR has since been widely adopted in various sectors, including development, humanitarian aid, healthcare, education, and business, to improve performance and learn from experience.
The goal of an AAR is not to assign blame but to foster open discussion, shared learning, and continuous improvement. It typically takes place immediately after a project, event, or activity, especially one that is complex, fast-moving, or has unexpected outcomes.
Key Questions in an AAR #
An effective AAR is guided by four core questions:
- What was expected to happen?
- What actually happened?
- Why were there differences?
- What can we learn from this?
Key Features of an AAR: #
- Participatory: AAR involves everyone who participated in the activity.
- Timely: It is conducted soon after the event to capture fresh insights.
- Constructive: It focuses on learning and improvement, not criticism.
Benefits of AAR: #
- It encourages continuous learning.
- It improves team communication.
- It enhances decision-making and planning.
- It builds accountability and trust.
Limitations of AAR: #
- AAR requires a safe and honest environment.
- It may be less effective if not facilitated well.
- It needs commitment to apply lessons learned.
In essence, the After Action Review is a powerful yet simple tool that promotes a culture of reflection and learning, helping teams adapt and perform better over time.
