After Action Reviews Explained for Organisations
An AAR (After Action Review) is a structured process used to evaluate what happened after an incident, emergency, project, or exercise.
It helps organisations answer four key questions:
- What was expected to happen?
- What actually happened?
- What worked well?
- What can be improved?
In simple terms, an AAR is used to learn from experience and improve future performance.
What Does AAR Mean?
AAR stands for After Action Review.
It is a formal review method originally developed by the military and now widely used in:
- Emergency management
- Government and public sector
- Corporate organisations
- Healthcare and critical infrastructure
The outcome of an AAR is usually documented in an After Action Report, which outlines findings and recommendations.
What Is the Purpose of an AAR?
The purpose of an AAR is to:
- Identify what worked well
- Highlight gaps or failures
- Improve plans, processes, and decision-making
- Strengthen future responses
Instead of assigning blame, an AAR focuses on continuous improvement and organisational learning.
What Are the 4 Steps of an AAR?
Most AARs follow a simple four-step structure:
1. What was expected to happen?
Defines objectives, roles, and planned actions.
2. What actually happened?
Reviews the timeline, decisions, and outcomes.
3. What worked well?
Identifies strengths and effective actions.
4. What can be improved?
Highlights gaps, issues, and lessons learned.
These steps form the foundation of any effective AAR.
When Should You Use an AAR?
An AAR should be conducted after:
- A crisis or emergency incident
- Business continuity activation
- Cyber or IT disruption
- Training exercises or simulations
- Major operational events
The goal is to capture insights while the information is still fresh.
AAR vs After Action Report
- AAR (After Action Review): The process of reviewing what happened
- After Action Report: The document summarising findings and recommendations
The review creates the insights — the report records them.
Why Are AARs Important?
Without an AAR, organisations risk repeating the same mistakes.
A well-run AAR helps:
- Improve crisis response capability
- Strengthen risk management
- Enhance communication and coordination
- Build long-term resilience
Every incident becomes a learning opportunity.
