Retrospect

One of the best ways to turn a bug fix into long-term engineering growth is to reflect on what happened and how to prevent it next time. Here are the core points from the lesson:

• After a fix, run a retrospective to figure out how to prevent or better handle similar issues in the future
• Writing a clean, detailed doc about the incident helps future engineers quickly learn without digging through scattered updates
• Big tech companies like Meta normalize failure and use formal SEV reviews to systematically improve after incidents
