Production Incidents
Overview
Production incidents are high-priority failures that affect users, systems, or business operations.
Why It Matters
Incident response protects users and keeps the team focused when pressure is high.
Core Concepts
- Stabilize first.
- Communicate clearly.
- Verify the system after the fix.
Mental Models
During an incident, the goal is to reduce harm and uncertainty, not to solve everything at once.
Best Practices
- Assign an owner.
- Track actions and timestamps.
- Prefer reversible fixes when possible.
Common Mistakes
- Jumping to permanent fixes before stabilizing.
- Losing track of what has been tried.
- Failing to communicate impact and ETA.
Trade-offs
Fast mitigation may not be the final fix, but it protects users while root cause analysis continues.

- Roll back a bad deploy before investigating the exact code path.
Checklists
- Is user impact understood?
- Has the team been informed?
- Is there a verified mitigation?
Senior Engineer Notes
Senior engineers stay calm, organized, and evidence-driven in incidents. The team remembers the quality of the response.
