Which process is focused on restoring service operation as quickly as possible following an incident?

The process focused on restoring service operation as quickly as possible following an incident is Incident Management. This process is critical in IT service management because it aims to minimize disruption to services and ensures that normal service operations are resumed as quickly as possible after an incident occurs. Incident Management involves logging, categorizing, prioritizing, diagnosing, and resolving incidents efficiently, ensuring that users can continue to work with minimal downtime.

Service Transition, while essential for managing changes to services, does not specifically target the immediate restoration of service operations after incidents. Service Level Management deals with ensuring that the agreed service levels are met, which is more about performance metrics than rapid incident resolution. Configuration Management maintains information about the components of the IT system but does not directly involve dealing with incidents or restoring services.
