Mirroring infrastructure's change management criticalities Support Ops defines changes on a C1 - C4 scale that helps determine appropriate planning horizons.
Criticalities can be estimated during a Requested Change and will be finalized once an issue is moved to the Support Ops project. The scheduling intervals indicate the delay between change announcement and change deployment.
When you first begin working an issue or MR, you should determine the change criticality of the task at hand. Once you have determined that, add the appropriate label to the issue:
Some issue and MR templates will automatically do this for you, but you should still review the task at hand to determine if the default value was accurate.
For guidance on determining the change criticality, see below.
Always use your best judgment on determining the criticality level. When in doubt, reach out to a Support Operations Manager for assistance.
These are changes with high impact or high risk that may significantly modify Support Engineer or Customer experience. If a change is going to cause downtime to the environment, it is always categorized a C1.
Some examples of Criticality 1 requests are:
These are changes that aren't expected to significantly impact Support Engineer or Customer experiences, but which still carry some risk of impact if something unexpected happens.
Some examples of Criticality 2 requests are:
These are changes with either no or very-low risk of negative impact, but where there is still some inherent complexity, or it is not fully automated and hands-off.
Some examples of Criticality 3 requests are:
These are changes that are exceedingly low risk and commonly executed, or which are fully automated. Often these will be changes that are mainly being recorded for visibility rather than as a substantial control measure.
Some examples of Criticality 4 requests are:
For every change criticality level, there are guidelines to utilize. This means that unless an exception is granted, nothing should be deployed before the required amount of time has passed. The guidelines are:
|Criticality||Timeframe||Who can approve exceptions|
|Criticality 1||4 weeks||VP of Customer Support|
|Criticality 2||3 weeks||Director of Support Readiness|
|Criticality 3||2 weeks||Support Operations Manager|
|Criticality 4||Can be done immediately||N/A|
If an exception is needed, ensure you ping your manager and the person(s) who can approve the exception. They must comment on the issue/MR granting the approval for the exception for it to be recognized.
Unless criticality 4, every change change should be communicated via:
Support Ops Announcementworkflow
Support Ops Announcementworkflow
All of the above should be done *every week leading up to the change occuring.
As an example, for a criticality 1 change occurring on 2022-12-30, you should be doing all of the above on the following dates at a minimum:
As another example, for a criticality 3 change occurring on 2022-12-30, you should be doing all of the above for the following dates at a minimum:
This is handled by the original requester of the issue/task. We handle the above communication, but the original requester should be encouraged to communicate to any other channels or teams they deem appropriate.
