What should be done with the written postmortem report before the postmortem meeting?

The written postmortem report should be completed and sent to attendees before the postmortem meeting to ensure that all participants have ample time to review the findings and insights. This preparation is crucial because it allows meeting attendees to come informed, facilitating a more productive discussion. The report typically includes details about the incident, what went wrong, what was done to mitigate the issue, and recommendations for future prevention. By reviewing the report in advance, participants can prepare questions, share insights, and contribute meaningfully to the meeting. This fosters a collaborative environment focused on learning and improvement.

The other options do not support the objective of a postmortem, which is to learn and improve future incident response. Destroying the report would eliminate any opportunity for analysis and learning, while discussing it during the meeting without prior distribution may lead to unprepared attendees, diminishing the overall effectiveness of the meeting. Keeping the report confidential contradicts the spirit of postmortems, which aim to promote transparency and shared knowledge among the team or organization.
