A briefing or analysis following the completion of an activity to see whether anything could have or should have been done differently. A process developed by the US Army to help teams to learn quickly from their successes and failures and share their learning with other teams. Involves conducting a structured and facilitated discussion after a task or project has been completed to review what should have happened, what actually happened and why it happened; this allows participants to learn how to sustain strengths and improve on weaknesses in subsequent tasks or projects.
