We have used OpsGenie for a couple of years on a very limited basis. Mostly individual groups using it for their own things without a lot of centralized standards. We're now expanding the use to all of IT, integrating it with ServiceNow and in general using it more as intended.
One issue that we're we're trying to head off before it happens is that when users want to add another team as a responder, or create an alert for another team, they have the option to add teams, escalations, schedules or users. Which is great, but it also opens up the possibility that they could send it to the wrong place and either have the notification missed because no routing rule exists or it could just be handled incorrectly (too aggressive / or not of a escalation policy).
How is this usually handled? Naming standards for common cross-team communication along with documentation and standards? Simply relying on educating users? Other ideas?
