The ITIL practices are those practices that the ITIL framework recognizes as practices. The ITIL definitions may differ from the others. According to the ITIL Foundation 4e by Axelos,

A practice is a set of organizational resources designed for performing work or accomplishing an objective.

In the ITIL universe, each practice supports multiple activities of the ITIL service value chain and includes resources based on the four dimensions of service management.

+:An [[incident]] is an unplanned interruption to a service, or reduction in the quality of service. The purpose of the [[incident management]] is to minimize the negative impact of incidents by restoring normal service operation as quickly as possible.
- ▪ An incident is an unplanned interruption to a service, or reduction in the quality of service.
- ● Incidents should be logged.
- ● Incidents should be managed to meet agreed target resolution times.
- ● Incidents should be prioritized.
- o Design the incident management practice appropriately for different types of incidents
- ▪ Incidents based on different impact
- ▪ Major incidents
- ▪ Information security incidents
- o Prioritize incidents
- ▪ Based on agreed classification
- ▪ Ensure incidents with highest business impact are resolved first
- o Use a robust tool to log and manage incidents
- ▪ Link to configuration items, changes, problems, known errors and other knowledge
- ▪ Provide incident matching to other incidents, problems or known errors
- o Incidents may be escalated to a support team for resolution. The routing is typically based on the incident category. Anyone working on an incident should provide quality, timely updates. Incident management requires a high level of collaboration within and between teams.
- o Some organizations use a technique called swarming to help manage incidents. This involves many different stakeholders working together initially, until it becomes very clear which of them is best placed to continue and which can move on to other tasks.
- ▪ Collaboration can facilitate information sharing and learning as well as helping to solve the incident more efficiently and effectively.
 ===Problem Management===

- ▪ Workarounds are documented in problem records
- ▪ Workarounds can be done at any stage, it doesn't need to wait for analysis to be complete
- ▪ If a workaround has been documented early in problem control, then this should be reviewed and improved after problem analysis is complete
