Should the results of an incident postmortem only be shared with the team(s) that participated in the incident response?

Sharing the results of an incident postmortem with a broader audience beyond just the immediate response team fosters transparency and encourages a culture of learning within the organization. By involving various teams and departments, the insights gained from the postmortem can be utilized to improve processes, prevent future incidents, and enhance overall organizational performance. This practice also promotes collaboration across teams, ensuring that everyone is aware of potential risks and lessons learned.

Additionally, including diverse perspectives can lead to more comprehensive and actionable outcomes, as others may identify additional risks or improvements that the initial responders may have overlooked. Therefore, the idea is to create an environment where knowledge is shared openly, leading to a more robust incident response strategy.

Limiting the sharing of postmortem results to only the teams involved or to upper management can lead to isolated learning experiences and may inhibit the collective growth of the organization.
