Do Team and Individual Debriefs Enhance Performance? A Meta-Analysis

Debriefs (or "after-action reviews") are increasingly used in training and work environments as a means of learning from experience. We sought to unify a fragmented literature and assess the efficacy of debriefs with a quantitative review.

Used by the U.S. Army to improve performance for decades, and increasingly in medical, aviation, and other communities, debriefs systematize reflection, discussion, and goal setting to promote experiential learning. Unfortunately, research and theory on debriefing has been spread across diverse disciplines, so it has been difficult to definitively ascertain debriefing effectiveness and how to enhance its effectiveness. METHOD: We conducted an extensive quantitative meta-analysis across a diverse body of published and unpublished research on team- and individual-level debriefs.
