It's on the checklist here at CPZ as well. I always felt that a 'debrief item' is as simple as saying 'great job', or 'thanks for all the help with that last minute runway change'. Or, as a more formal 'yeah, we'd better file a crew report/ASAP because xxxxx happened'. More of a memory jogging device on the checklist than anything else. But I don't want to wade into the deep waters of tooldom so I'll leave it at that.
