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. That would be the number one thing. Our boss says all the time, "Well, you got to create them and add them to the group," but we can't exactly add them to a group because we're not on that team. We don't know if they should be on-call, and if they should, whether the shift they have installed is during the business day, after-hours, or a weekend. Everybody has got their own shift created, and we would not know what shift to put them in. We could start asking that on new user creations, but when we're doing new hires, it's more or less just common practice to create all their accounts. We can't create an X manager's account for a few things. That's not how we have it set up. We could change all of that, but that's where there is a gap. One of the shortcomings or room for improvement is that their mobile application seems subpar. They could really revamp it and make it function a lot better. There have been too many times when it timed out, and you don't even get to know it. You could go a month or two months without getting an on-call alert, and then, you get one, but it is never alerted in the application. So, if you don't have your cellphone number set up, you'll never get notified, and then you go back to the app to find out that it has automatically logged you out, and you can't get back in. The mobile applications, for both iOS and Android, should definitely be revamped.
