Which of the following is considered a special type of incident?

In the context of ITIL and the management of incidents, the concept of a "special type of incident" typically refers to those incidents that significantly influence business operations or require unique handling based on their characteristics. The correct answer highlights that an incident with no business impact does not fall into the category of being special.

Incidents that do not affect business processes or services do not necessitate special attention or handling and, therefore, do not retain the same level of urgency or importance as those that pose a risk to service performance or business objectives. This aligns with the ITIL principle of prioritizing incidents based on their impact and urgency.

In contrast, an incident with significant business impact and those requiring immediate user notification are elements that would necessitate being treated as special incidents due to their potential to disrupt normal operations and the need for swift communication and resolution. Meanwhile, incidents of average severity, by definition, indicate a level of impact that does not classify them as special either.

Understanding the nuances of incident classification in this way helps to prioritize responses and resource allocation effectively in IT service management.
