Communication: Always Include Incident Impact On Business

When an incident happens, most engineers rush to explain the technical details.

That is the trap.

The business first needs to understand impact: who is affected, what is unavailable, and how much risk this creates right now. If Redis is down, “Redis is down” is not enough. Say what this means for users, operations, and revenue.

The Trap Most Engineers Fall Into

Most incident updates start with implementation details: logs, stack traces, host-level behavior, and speculative root causes.

Those details are useful for engineers, but they are not the first thing the business needs. Impact-first communication builds trust because it answers the decision-making question immediately: “How bad is this, and what should we do now?”

First Response: What to Include in the First 5 Minutes

Your first message should be short and structured:

1. What happened (one sentence)
2. Current business impact
3. Scope (which users, regions, products)
4. Mitigation status (what is being done now)
5. Next update time

A good first response is not a full diagnosis. It is clear situational awareness.

Incident Report / Post-Mortem: What Must Be Included

For the written report, include the technical details, but keep them in the right order:

1. Impact summary (with time window and measurable effect)
2. Timeline (detection, escalation, mitigation, recovery)
3. Root cause analysis (technical and process causes)
4. Detection gap (why alerts/checks did not catch it earlier)
5. Corrective actions (owner and due date for each item)

Root cause without impact is incomplete. Impact without corrective actions is also incomplete.

Conclusion

During incidents, technical precision matters, but communication priority matters more.

Start with business impact, then add technical depth. Engineers who do this consistently become trusted much faster, especially as they grow into senior and leadership roles.
