debrief

debrief — To have a meeting or discussion after an event to analyze what happened, what went well, and what could improve.

In simple English

In tech companies, debriefing is a critical practice after significant events like product launches, incidents, outages, or major milestones. During a debrief, team members discuss what occurred, why it happened, what worked, and what needs improvement. This is different from a briefing, which happens before an event. Debriefs can be formal or informal depending on the situation. For example, after a failed deployment, the team might debrief to understand the root cause. After a successful hackathon, teams might debrief to capture lessons learned. The goal is always to learn and improve future outcomes.

How to say it: Say dee-BREEF.
