In terms of intuitiveness and flexibility of xMatters when it comes to customizing on-call schedules, rotations, and escalations, for me, as an IT professional, setting it up isn't that big of a deal, but I understand that some people struggle with it because when you get wrapped up into it. You can get lost. It's not super complex, but it's complicated enough to the point where you can say that you should have done it another way. The shift part can be confusing for some people. In that respect, one of the shortcomings my team has found is when we have to add another person, such as a new hire, to xMatters, we can't add them to a group within xMatters without having to put them on a shift. If we put them in a group, they have to be on-call. We can create their account, and then they're just out there in limbo until their team says, "You have to be on this shift." One piece of feedback for xMatters is to figure out how to have manageable groups so that they're contactable from xMatters. They do not necessarily have to be on a shift right from the start or at all for that matter.
