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

- Automated stakeholder notifications at defined intervals during active incidents
- Post-incident review templates and problem management workflows to close the loop

## 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](https://jestor.com/?ref=blog.jestor.com) 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.
