incident

In simple English

In tech companies, an incident refers to any unexpected event that negatively impacts your systems, services, or users. This could range from a server outage, database failure, security breach, or performance degradation to configuration errors. Incidents are tracked, prioritized, and managed through formal processes because they affect business operations and user experience. Incidents are different from bugs or feature requests because they demand urgent attention. When an incident occurs, teams typically enter an incident response mode, which includes notification, assessment, mitigation, and post-mortem analysis. The severity of an incident determines how quickly it needs to be resolved — a critical incident affecting all users gets different treatment than a minor incident affecting one customer. Understanding incident management is essential for engineers because it shows professional communication, prioritization skills, and system reliability thinking. You will hear terms like incident report, incident commander, incident severity, and incident response procedures in your daily work.

Say it like this

✓We have an active incident on the production database.
✓The incident is still ongoing; please stand by for updates.
✓This incident requires immediate escalation to senior engineering.

Real examples

in a standup

"We need to discuss the incident that happened last night with the API gateway."

in a slack message

"An incident has been declared — please join the war room bridge."

in an email

"The incident severity has been downgraded from critical to major as services are now recovering."

Don't say this

Handle with care. Do not confuse incident with accident — incident is broader and includes any unplanned event affecting systems, while accident implies unintentional harm. Also avoid treating incident as a verb; it is only a noun in tech contexts.

✕We had an incident happen to our server yesterday.
✓We had an incident with our server yesterday.— Use the preposition with, not to, when describing what system was affected by an incident.
✕The incident is incidenting our users.
✓The incident is affecting our users.— Incident is a noun only; do not try to use it as a verb. Use affecting, impacting, or disrupting instead.
✕We need to incident this bug before launch.
✓We need to resolve this bug before launch.— Incident describes a problem that has already happened, not an action you take. Use report, declare, or resolve instead.
