Postmortem Builder allows users to learn from major incidents by providing a summary of events that transpired, how the response was handled, and what resolution steps were taken. It offers the ability to curate a timeline of activity in PagerDuty and Slack, allowing further analysis to determine follow-up actions for similar situations in the future and, ideally, help prevent them altogether.You must have an active PagerDuty account to install and use this app.
