How to Handle Major IT Incidents Through Your Service Desk
A major IT incident is any unplanned disruption that significantly impacts business operations—a system outage, a data breach, a critical application failure. Handling major incidents effectively requires a predefined response process that can be activated under pressure, with clear roles, escalation paths, and communication protocols already in place before the crisis happens.
Why Major Incident Response Fails Without a Process
When a major incident hits an unprepared service desk, the typical result is reactive chaos: multiple people trying to fix the problem simultaneously, inconsistent communication to affected users, and no clear owner coordinating the response.
A structured major incident process doesn't prevent outages—but it dramatically reduces their duration and business impact.
The Phases of Major Incident Management
A complete major incident response process covers five phases:
- Detection and classification: The incident is identified and classified as major based on predefined criteria (system scope, number of affected users, business impact threshold)
- Escalation and mobilization: The Major Incident Manager is activated; relevant technical teams are assembled; a bridge call or war room is opened
- Investigation and diagnosis: Technical teams work to identify root cause while the incident manager coordinates communication
- Resolution and recovery: The fix is applied, systems are restored, and the incident is confirmed as resolved
- Post-incident review: A structured retrospective documents root cause, timeline, and preventive actions within 48–72 hours
Key Roles in Major Incident Response
Every major incident response needs clearly defined roles:
- Major Incident Manager: Coordinates the response, owns communication, and drives the team toward resolution
- Technical Lead: Responsible for the diagnosis and fix within the affected system domain
- Communications Owner: Manages updates to business stakeholders and affected users throughout the incident
- Problem Manager: Takes over after resolution to lead the root cause investigation

FAQ
What qualifies as a major IT incident? Typically: a critical system down, multiple business users impacted, or a security breach. Define your threshold in advance—don't decide under pressure.
How long should a major incident review take? The post-incident review should happen within 48–72 hours of resolution while memory is fresh. Jestor provides templates to structure it.
Who is responsible for a major incident? A designated Major Incident Manager owns coordination. Without a single owner, response becomes fragmented and slower.
