Glossary

Targeted or Soft freeze: Some services are more critical during certain periods such as clearing or enrolment, where the impact of a service interruption due to a change would be greater. A targeted freeze period will apply to such critical services.

Hard freeze: During a Hard freeze, no non-standard changes will be implemented to ANY IT service. 

Change Freeze Exception Process: If it is essential for a change to be made during a freeze, it will need to follow the Change Freeze Exception Process which requires assessment of the risk of delaying the implementation and Assistant Director approval.

Change Schedule: To check dates specific to a particular year please refer to the shared calendar in MS Outlook/Office 365 (from your Outlook calendar > click on Open Calendar (under the Home tab) >  click on From Address Book... > search for ‘[Shared] ITS Change Schedule’).
