I have been using JIRA and its different versions, distributions, add-ons for a time now.This is one of the best-known yet expensive solution for ticketing, and one of the best working one.You may check what points I have collected for pros and cons, yet if I could, I would use and recommend JIRA.The interface what most people "ragging" about JIRA, indeed needs to time to get familiar with, but Salesforce and its chatter, JIRA is still better.There are training material, some on-boarding also available in-built for JIRA and after a few ticket, you are ready to go on your own.In every sector you can find ticketing tools, JIRA is customizable according to your needs.If a lot of people are going to use it, I recommend to have an on-premise solution with a lot of power.There are rivals to JIRA, even in-house ticketing tools, in my company now we have 2 systems, yet an IT-provider can use a lot of them, causing a chaos.JIRA is continuously being developed, there are 3rd party extensions to it, quite stable.

Ottima, sicuramente il miglior strumento di supporto nei progetti Agile per tracciamento e gestione del product backlog.

Jira is a complete solution for tracking an historic even and related events as the tickets and sub tickets are linked under one roof.

Overall, I would highly recommend Jira to any business or organization looking for a powerful and flexible project management software. Whether you're a small team or a large enterprise, Jira offers the features and functionality you need to manage your projects effectively and efficiently.

Initial setup can be complex but it can also be super powerful if you are able to configure it properly. It's visual scripting and workflow tool is really capable and easy to learn
