Changes in the IT environment

Anything that affects the IT environment is defined as a change and must be handled by the change process. The decisions are made by the change councils called CAB and eCAB.

Examples of changes:

  • Replacement of central systems
  • Introduction of new central system
  • Abolition of a system
  • Open/close firewalls
  • Policy change
  • Various updates, such as a new version of something
  • Change of servers
  • Implementation/change of a routine in daily operation

There are two different types of changes:

  • Regular changes, handled by a CAB, (follows the standard procedure)
  • Urgent changes, handled by an eCAB, (changes that cannot be notified in time but must be handled separately)
