Use this skill when an incident or a serious near miss is closed and the team must learn from it, or an auditor asks for lessons learned, and someone says "run the post-mortem", "post-incident review", "lessons learned", "retro on the outage", "blameless review", "root cause of the incident" or "what do we change after this breach".
