My team manages the xMatters platform for our company. We're not just end-users of the platform. We configure and manage the platform for our company.
So, I'm probably a superuser.
I wasn't around when they started the implementation process, but I know what they basically needed was real-time alerts. So, if somebody were to create a high-priority incident and we had something that was production-down, we needed to alert the appropriate people in order to get that resolved. If I remember correctly, they didn't have anything before xMatters, or the solution they did have was very flaky and didn't process as xMatters would. So, the use case for it was to get less downtime.
There is also the business continuity side, such as knowing what locations people are in, where xMatters is used a lot more than the IT side. For example, if there is an active shooter in a single location, you can use the business continuity side of xMatters to send out an alert to all of the employees asking them to take cover, get out, and do something, or if a building blows up or is on fire, you can send out a message through the business continuity to say that nobody comes to work.
