Important ITIL processes and functions

Let’s explore basic ITIL processes and their functions.

ITIL processes and functions

Incident management

Any degradation of service in the IT department is an “incident”. Incident management is a quick restoration of service. But this should have little or no impact on business operations.

We have five types of incidents: P1, P2, P3, P4 and P5.

Priority = Impact + Urgency

The incident management process ensures that the expected quality of service is achieved and delivered.

Problem management

A problem is an unknown cause of one or more incidents. And preventing a problem or incident is problem management.

You will need to perform a root cause analysis (RCA) to understand the root cause of a problem before you can fix it.

This process improves the availability of services and the quality of IT services provided by ITIL users.

Change management

This process is used to improve or modify service operations. Changes are recorded, planned, designed, tested, and first implemented in the lower environment. And then, if they work as expected, the changes are moved to service operations.

However, it is recommended to ensure that before making any changes to service operations, there is a recovery plan.

Every change must be recorded and must be approved by authorized persons. These authorized persons would be one of these persons:

CAB – Advisory Committee on Change

ECAB – Emergency Change Advisory Committee

Version and deployment management

This process ensures that the required changes are first tested and deployed in a lower environment. And then if they work as expected, those changes are moved to service operations.

Access management

This process controls access to applications. Authorized users have access to applications and unauthorized users are denied access. This feature ensures that only authorized users can access the services.

Service level management

Service level management ensures the timely delivery of all IT services.

Availability management

Ensure service availability is provided in all departments according to the agreed schedule.

Service Desk: This team is responsible for restoring service to users as quickly as possible, in the event of a service failure.

IT Operations Management: This responds to day-to-day operational activities. Mainly the activities necessary to manage and maintain the IT infrastructure of an organization.
