This is basically every major enterprise ticketing system. They’re typically extremely customizable over-featured behemoths so that they can check all the buzzword boxes for the people that make purchasing decisions but will never actually use the system.

"It’s a fully integrated Agile ITIL DevOps CMDB that empowers your users while providing generative KPIs to guide business decisions!”

Then, on top of that, ownership of it is generally dropped on a team that is completely incapable of properly managing it from both a technical ability and sheer manpower availability standpoint. So each install ends up becoming an overly complex, confusing, terribly performing mess.

I think I’ve seen one reasonably well managed install in the couple decades I’ve been doing this, a couple of more that were mildly jank but usable, and then everything else has been a pit of despair largely driven by the above.
