Post-mortem software features: Separating must-haves from nice-to-haves

Post-mortem software is essential for modern Site Reliability Engineering (SRE) teams, primarily because it automates the otherwise tedious and error-prone process of reconstructing incident timelines, which can take 60-90 minutes. By capturing every action during incidents in real-time and integrating seamlessly with tools like Slack, Datadog, and Jira, platforms like incident.io significantly reduce the time needed for post-mortem documentation from 90 minutes to just 15. Key features to prioritize include automated timeline capture, Slack-native workflow integration, bi-directional tool integrations, and AI-assisted drafting, which together shift engineers' focus from manual data reconstruction to high-value analysis and learning. While additional features like custom branding and complex approval workflows are often deemed unnecessary, the primary goal is to expedite the transition from incident resolution to published learning, enhancing the team's ability to prevent future incidents.
