Summary

An After Action Review (AAR) is a short, structured team debrief built around four questions — What did we expect? What actually happened? Why the difference? What do we do differently next time? — run after every milestone or action, not just at the campaign’s end.

Body

The AAR was developed by the U.S. Army and adopted across project-management and aid-evaluation practice. The campaign-adapted version is a 30–60 minute debrief the team runs after every milestone or named action. The four questions are:

  1. What did we expect to happen? What was the plan, the forecast, the assumption set?
  2. What actually happened? What did the data, the response, the outcome show?
  3. Why the difference? What in the assumption set was wrong, and what in the context shifted?
  4. What do we do differently next time? What concrete change enters the ToC, the risk register, the plan or the kanban?

The Commons Library’s Campaign Accelerator trains campaigners to run an AAR after each action and to file the lessons back into the theory-of-change and the risk register [source: commons-library]. The ALA Frontline Advocacy Toolkit’s evaluation chapter recommends the same discipline in library advocacy, with the explicit warning that skipping AAR when an advocacy project “appears to be finished” loses the lessons the next project depends on [source: ala-frontline]. The People Power Manual pairs the AAR with the Evaluation and success indicators chapter: AAR is the team’s internal learning mechanism; outcome evaluation is the external report [source: people-power-manual].

A useful AAR has five properties:

  • Blameless. The fourth question is forward-looking — what do we do differently? — not backward-looking — whose fault was it? Blame shuts down the information the AAR is designed to surface.
  • Time-bounded. 30–60 minutes. An AAR that runs for two hours has become a debate.
  • Owner of the lesson. Each AAR produces at least one named change to a specific document (ToC, risk register, plan) and a named owner.
  • Run even on a win. Wins hide mistakes — the why the difference? question is often most useful on a campaign that hit its goal through luck rather than the assumed mechanism.
  • Run at every milestone. Not just at the campaign’s end. The Commons Library treats the AAR as the rhythm that closes the campaign-cycle feedback loop [source: commons-library].

A common failure mode is to treat the AAR as a meeting rather than a discipline. The ALA Frontline Advocacy Toolkit warns that an AAR without a named owner of the change becomes a discussion without a result [source: ala-frontline]. The People Power Manual adds that an AAR that does not update a document is decorative: the lesson should enter the ToC, the risk register, the campaign plan or the kanban, and the document should change visibly [source: people-power-manual].

Closing the feedback loop at every milestone of the the-campaign-cycle; turning campaign experience into organisational learning; diagnosing why a tactic worked or did not; running a coalition debrief; producing the lessons the next campaign’s theory-of-change needs.
