The table below outlines the various event driven IT change freeze periods throughout the Academic year (September to August). A freeze on changes to the IT environment is imposed during critical events to minimise the risk system failures and downtime impacting critical and high profile events.

Change freeze exception process

During a change freeze the individual responsible for implementing a change will need to consider the effect of delaying implementation until after the change freeze (the Business Service Owner will need to be consulted).

i) The Change Creator must make an assessment and a recommendation. If the recommendation is that the change cannot wait until after the change freeze, they or their manager must email details of the change to their Head of Service (HoS) with the recommendation to proceed.

ii) If the Head of Service agrees that the change cannot wait, they must email details to their Assistant Director (AD) requesting approval to proceed. If the AD agrees, the change can be progressed as normal via technical approval, for assessment by the Change Manager. Evidence of HoS and AD approval must be included in the change request ticket.

iii) In addition to Change Manager or CAB approval, the Change Manager will seek approval from the Assistant Director IT Operations before finally approving the change. Where the AD IT Operations was the primary AD approver in step ii, no further AD approval is required

Glossary

'Targeted' or 'Soft' freeze or 'change frost' (heightened awareness): Some services, dependent on infrastructure and/or interfaces might be more critical during certain periods where the impact of a service interruption due to a change would be greater. Those services should be itemised where possible so it is clear which ones are 'frozen' and which services are excluded from the freeze. The list of frozen services should be added to the Change Schedule on the calendar in Office 365 for the period of the freeze (see calendar named ‘[Shared] ITS Change Schedule’). If changes are planned to happen during the freeze they will need to follow the Change Freeze Exceptions Process. Greater due diligence regarding the risk assessment should be given and assess the risks of delaying the implementation until after the 'soft freeze'. If in doubt, ask technical peer/teammate or line manager. If still unsure, ask the IT Change Manager.

Hard freeze: No non-standard changes to any IT service to be implemented during a hard freeze. Standard changes will normally be excluded from change freezes but this will be a conscious decision.
