Plant IT Outage Incident Report (Post-Incident Review) Template
When the ERP or plant network goes down, management wants a short, factual answer: what broke, how long, what it cost and what will stop it happening again. This template structures that answer.

Incident Report INC-0932
Site: Plant 2, Monterrey Severity: Sev 1 (plant stopped) Start: 2026-09-18 06:42 Restored: 2026-09-18 09:15 Systems affected: ERP application tier, MES terminals, label printing
Summary
The ERP application server stopped responding after the primary storage array switched controllers. Terminals on assembly lines 1 to 3 could not post production.
Impact
About 2.5 hours of lost transaction posting. Operators recorded output on paper; backflush was posted afterward. Two customer shipments left late.
Timeline
| Time | Event | Who |
|---|---|---|
| First alert or user report | ||
| Incident declared and bridge opened | ||
| Cause identified | ||
| Fix applied | ||
| Service verified and users notified |
Root Cause
Firmware bug on the array controller triggered a failover that did not complete cleanly. Monitoring alerted on CPU but not on datastore latency.

Summary of actions
Apply the vendor firmware fix, add datastore latency alerting, and rehearse the paper fallback procedure with shift leads.
Review and Sign-off
Keep reviews blameless: describe system and process failures, not individuals. Adapt severity names to your own incident policy. Starting point only.

How to use the report
Start the document while the incident is running, even if only the start time and systems affected are filled. Record the timeline from tickets, chat logs and monitoring rather than memory. After service is restored, run a review within a few days, complete root cause and actions, then export to PDF or Word for the plant manager and any customers who were affected.
Writing a useful root cause
A good root cause explains why the failure happened and why it was not caught earlier, not just the trigger. 'Storage failover' is a trigger. 'Failover bug combined with no latency alerting' is a cause you can act on. Use the five whys or a simple fishbone, and separate contributing factors such as missing monitoring, untested fallback or unclear escalation.
- State the trigger, the detection gap and the recovery delay
- Separate cause from the workaround used
- Link each cause to at least one action
- Avoid naming individuals
Quantifying production impact
Plants care about lost transactions, stopped lines and late shipments. Estimate impact with ranges and plain mechanisms: hours of downtime multiplied by affected lines, plus catch-up posting effort. Avoid precise cost claims unless finance has confirmed them. Note whether manual fallback worked, since that is often the largest lesson.
Common mistakes
Frequent errors include closing the report with no owners or dates on actions, blaming a vendor without checking the monitoring gap, and failing to test the corrective action. Also review whether the same failure mode exists at other plants. Track actions to completion in your ticketing system, not only in the report.
Frequently Asked Questions
When should I write a formal incident report?
Write one for any outage that stops production, affects customers or breaches an agreed service level. Many teams also review near misses. Smaller incidents can use a short ticket note instead of the full form.
What is the difference between an incident and a problem?
In ITIL terms an incident is the service interruption you restore quickly, while a problem is the underlying cause you investigate to prevent recurrence. This report covers both: the timeline for the incident and the root cause and actions for the problem.
Should the report go to customers?
Sometimes. If a late shipment resulted, a short customer-facing summary of cause and prevention is often appreciated. Strip internal system names and security details first, and have the plant manager approve what is shared.
How long should the review take?
Hold the review within a few working days while memory is fresh, and keep it to an hour. Bring the timeline, monitoring graphs and fallback evidence. Finish with owners and due dates for every action.
Netray can discuss how ERP-aware monitoring and natural-language questions over production data could shorten the impact assessment after an outage.
