At the Navy SEALs, such uncomfortable, candor-filled moments happen in the After-Action Review, or AAR. The AAR is a gathering that takes place immediately after each mission or training session: Team members put down their weapons, grab a snack and water, and start talking. As in BrainTrusts, the team members name and analyze problems and face uncomfortable questions head-on: Where did we fail? What did each of us do, and why did we do it? What will we do differently next time? AARs can be raw, painful, and filled with pulses of emotion and uncertainty.
