After a service outage, what is an effective way to address concerns from another team regarding incident explanations?

Creating a detailed postmortem and sharing it on the engineering organization's document portal is an effective way to address concerns from another team regarding incident explanations because it fosters transparency and accountability. A thorough postmortem provides insights into what went wrong, the impact of the incident, the root cause analysis, and the steps taken to resolve the issue. By documenting this information comprehensively, it allows all stakeholders, including those from the requesting team, to understand the incident fully and learn from it.

Additionally, sharing the postmortem on a centralized document portal ensures that the information is accessible to everyone in the organization. This open approach not only promotes a culture of learning and improvement but also helps build trust between teams by demonstrating that issues are being addressed systematically and that there is a commitment to preventing similar incidents in the future.

In contrast, the other options do not effectively convey the seriousness of the incident or ensure that all relevant parties have the necessary information to learn from it. Limited sharing can lead to misunderstandings and the potential for repeated mistakes, as knowledge is not disseminated across the team.
