The main problem I have with ticketing (and project management) systems is that I can't get the people asking me to do things to use the system. I'll set it up and show them how to use it, and then they tell me about issues via email or text message or voice call. I end up entering the tickets/tasks myself, at which point I might as well be using my own org-mode setup.
From all I've seen, heard, and read about that problem over the decades (yup, I think it's not mere years any more):
The only solution is to be rock-solid in refusing to do anything if there isn't a ticket for it. Your nine-thousand-percent-consistent reply to those emails, text messages, and voice calls needs to be "Yeah, make a ticket about it. I've shown you how, and that's the way we do it. No ticket, no action from me."
If you can't be that "mean" about it, you'll have to be a make-my-own-tickets doormat forever. In that perspective, doesn't feel all that "mean" any more, does it?
Where I'm at, we have a bot that automatically creates a ticket for IT any time someone posts a message to the #it-help channel on Slack. It even automatically routes the ticket based on the content of the message with decent accuracy.
Perhaps I've been spoiled having worked almost exclusively in organizations where it's completely acceptable to get a message on Slack, or Teams, or email, or whatever, with some bug or issue, and respond with "please create a ticket" and the person... creates a ticket.
Yeah if nobody uses the system, or if you have to expend organizational capital to get them to do it (they view it as doing something for you instead of just doing their job), the system will by definitely be worth less and be less helpful.
